6 Steering systems. A standard feature from CLAAS for many years. Electronic systems are fast becoming a standard feature. Since the introduction of satellite-based steering systems to agriculture, more and more farms have been reaping the benefits of this technology. They are upgrading their tractors and harvesters and enjoying the daily advantages of highprecision parallel steering systems in the field. The existing interface between GPS PILOT and AGROCOM NET and AGROCOM MAP CLAAS farm management software allows tramlines, reference lines, and job-specific information to be easily exported to the farm s PC by way of simple transfer via a USB stick. Steering systems are indispensable. Our CLAAS GPS PILOT supports your work in the field or pasture. Precision to the nearest centimetre is now made easy. Make every track exactly the same as the previous one Make full use of the working width Reduce overlapping Save valuable operational time, or extend it into the nighttime hours Optimise the cost-efficiency of all your working processes Forward planning for the next job enables all field-related and job-related data to be used without having to repeat the data gathering process. 6

Benefits 7

8 The ideal introductory system. The GPS COPILOT manual steering system.

9 GPS COPILOT GPS COPILOT TS Satellite-based steering systems

10 GPS COPILOT. Optimise resources. Cut costs. Making it easy to get started. The GPS COPILOT is the ideal CLAAS entry model for satellite-based steering systems and offers a rich range of functions. The driver guided by the EGNOS satellite signal (with no licence fee) can steer the machine safely and securely in parallel lines or along variable contours with a GPS accuracy of +/ 15 to 30 cm. The system enables the operator to utilise the machine s full working width and reduces overlapping. This boosts the quality of work while reducing the work time especially in difficult light and weather conditions. 10

11 The GPS COPILOT can mainly be used for the following job types: Tillage Fertiliser application Slurry application Manure application Lime application It can also be used for other jobs falling within the given accuracy range where there are no points of orientation such as tramlines on the field. Features that professionals value highly. Automatic reference track offset Integrated area calculation Headland alarm Can be used flexibly on any machine Short set-up times RS-232 interface for outputting correction data GPS COPILOT 11

12 Easier steering. The GPS COPILOT TS is suited to all operations and is very user-friendly, thanks to its touchscreen display with graphical user interface and zoom function. The terminal uses the EGNOS correction signal (with no licence fee) as standard, and can be expanded at any time to include features ranging from parallel guidance to the GPS PILOT automated steering system. In addition to integrated job management, the COPILOT TS provides an interface to the CLAAS AGROCOM NET and AGROCOM MAP farm management software. This allows recorded data such as tramlines, reference lines and job-related information to be transferred to a PC, making it permanently available for every kind of documentation for many years. 12

13 GPS COPILOT TS. Accurate steering. Benefits.

15 GPS PILOT S3 GPS PILOT FLEX GPS PILOT CEBIS MOBILE Satellite-based steering systems

16 GPS PILOT with S3 Terminal. The GPS PILOT S3 for automatic steering has an 8.4" colour display and touchscreen user interface. Four different views guarantee a perfect overview and facilitate the job in hand. Speed and position data via RS 232 connection, and data exchange and program updates via USB ensure maximum performance and convenience. The interface between GPS PILOT and AGROCOM NET and AGROCOM MAP the CLAAS farm management software ensures recorded tramlines, reference lines and job-related information can be used and managed. This allows ongoing use and management of all gathered data for many years. The 1 GB internal memory is sufficiently large for the applications at hand, and allows jobs to be sorted by field, farm, driver, and machine within the integrated job management. 16

17 GPS PILOT S3. Precision all along the line. Convincing arguments 1 High-resolution touchscreen display: the large colour display is very user-friendly and provides a whole range of functions. 2 USB-2.0 port: the USB interface can be used to transfer jobs/reference lines stored in the internal memory. 3 View mode: you can simply switch between machine view and field view. You have the best overview at all times and can maximise your efficiency. 4 Settings menu: provides simple access to basic settings (working width, overlapping, job creation and job management). 5 Zoom function: user-specific adjustment of the driving view. 6 Working menu: no need to scroll through the menu. Direct access to start/stop function, drop markers when working the field, change driving mode. 7 AUTO TURN: automatic turning at the headland makes it easy to line up with the selected track with maximum accuracy. GPS PILOT S3 17

18 GPS PILOT S3. Better than ever. AUTO TURN. With AUTO TURN, accurate parallel tracking after automatic turning at the headland is no problem at all. This optional function prevents the inaccuracies (overlapping, untreated areas, large curves) which occur when manually lining up the machine with the next parallel track. Precision from the very first metre ensures that crooked crop rows postemergence are a thing of the past. AUTO TURN also enables the operator to concentrate on controlling and monitoring the attached implement and to establish blocks automatically. Just set the number of tracks to be skipped and the machine lines up perfectly. Turning becomes significantly easier even in difficult conditions such as working at night or in fog or dust. 18

19 SECTION VIEW. No more unwanted overlapping when spraying or applying fertiliser. SECTION VIEW displays the sections that need to be switched off. The width of up to 10 sections can be freely defined, depending on your implement. The degree of overlap can also be adjusted when the display is operating. Benefits: Sections to be deactivated are displayed No unnecessary overlapping Cost savings GPS PILOT S3 19

20 The right speed for every application. With the CLAAS GPS PILOT S3 you can access a range of speeds which meets every field work requirement (25 km/h to 400 m/h). Benefits: High accuracy at all times and at all speeds 400 m/h to 25 km/h Ideal for farms growing specialised crops Ideal for all types of work, from rotary cultivation tasks which move a lot of soil to planting, the GPS PILOT S3 provides a virtual string which ensures that your rows are completely straight. When working with modern seed drills, speeds of up to 20 km/h are the norm. Even at these speeds, the GPS PILOT S3 guides the tractor and implement across the field in a perfectly straight line while maintaining the required accuracy. 20

21 GPS PILOT S3. Even greater accuracy, even easier to use. Data transfer between machine and office. The amount of documentation required is making the paperwork more and more time-consuming. With the CLAAS GPS PILOT S3 and the AGROCOM NET and AGROCOM MAP farm management software you can reduce this work to a few mouse clicks. The data recorded in the field (field boundary, reference track, time, return points, job information: field name, driver, machine, implement) can be exported from the terminal onto a USB stick and then imported into the software. It is just as easy to prepare the work to be done in the software then export it to the GPS PILOT S3 terminal. Would you like to inform other machines about a reference line for parallel tracking in a particular field? You can do this easily by exporting and importing the data using a USB stick. GPS PILOT S3 21

22 GPS PILOT S3. Components. Description of the components. 1 GPS PILOT receiver: this high-precision receiver transfers the GPS position data to the terminal. 2 GPS PILOT terminal: the GPS PILOT terminal calculates the exact passes from the DGPS position data received, taking account of working width. 3 Navigation computer: the navigation computer with its 6-axis gyro provides maximum compensation for sideto-side movements, pitch and yaw. 4 Steering technology: the proportional steering valve and wheel angle sensor are responsible for making accurate steering movements. 22

23 Universal use. The GPS PILOT S3 is a steering system for all makes of machine and can be used with all machine types, including tractors, combine harvesters and forage harvesters. Depending on the application or machine, you can decide whether to use hydraulic steering or an electrically powered steering wheel. With GPS PILOT S3 you can equip your entire machinery fleet with an automatic steering system, regardless of manufacturer. GPS PILOT S3 23

24 Highly versatile. In addition to hydraulic steering, the GPS PILOT S3 can also be used with an automatic steering wheel, the GPS PILOT FLEX. This steering wheel gives highly accurate steering performance. The great advantage of the GPS PILOT FLEX is its versatility. It is easily transfered between machines which are only used on a seasonal basis such as combine harvesters and forage harvesters; as a result, RTK accuracy can be available on the tractor for drilling. It is also designed to allow the steering wheel solution to be installed on older CLAAS machines or machines from other manufacturers. A number of options are available. You can use existing GPS PILOT S3 equipment on the individual machines and just change the steering wheel, or you can move the whole system between machines. Naturally, all the well-known features of the GPS PILOT S3 such as AUTO TURN, SECTION VIEW, job management, etc. are still available, as are the different driving and steering modes. Multiple selling points: No need to touch the hydraulics Steering system can easily be moved between different machines Accuracy is comparable with that of hydraulically steered machines All the functions of the GPS PILOT S3 24

25 GPS PILOT FLEX. Description of the components. 1 GPS PILOT receiver: this high-precision receiver transfers the GPS position data to the terminal. 2 GPS PILOT terminal: the GPS PILOT terminal converts the GPS position data received into steering signals. 3 Navigation controller: the navigation conroller with its 6-axis gyro provides maximum compensation for longitudinal and lateral movements. 4 Steering technology: the electric steering wheel transfers steering commands from the terminal and navigation controller to the steering axle in order to steer the machine. GPS PILOT FLEX 25

26 GPS PILOT CEBIS MOBILE. Unrivalled convenience. GPS PILOT with CEBIS MOBILE terminal. GPS PILOT uses the multifunctional colour CEBIS MOBILE display. The terminal has a 6.4" colour display, the same operating structure as the well-known CEBIS on board, and serves as an additional terminal for process optimisation. CEBIS MOBILE is not only deployable on the LEXION at harvest time, but can of course also be subsequently used for GPS steering on the tractor. The fully ISOBUS-compatible terminal can additionally be used for controlling attached implements and for displaying other functions such as variable application (VA). GPS PILOT and, for example, CEMOS, can run simultaneously on the CEBIS MOBILE terminal, and the desired application can be displayed at any time. 26

27 Convincing arguments 1 High-resolution display: the 6.4" colour display is very user-friendly and provides a whole range of functions. 2 The main menu bar: provides easy access to basic settings (general settings, machine and system configurations, field administration, calibration, and diagnostics). 3 Driving mode menu: direct access to the desired driving mode setting, such as A-B straight and A-B contour. 5 View mode: you can simply switch between navigation view and field view. 6 Status display: all key information such as satellite reception, active alarms and selected driving mode. 7 Implement deviation monitoring: bar-graph display for visual monitoring of implement deviation from the desired track. 8 Display for menu-dependent functions: direct centring and adjustment of reference lines. 4 Reference line management: direct access to stored reference lines. GPS PILOT CEBIS MOBILE 27

28 One terminal, many uses. Whether you use the CEBIS MOBILE for the GPS PILOT on a CLAAS harvester or a CLAAS tractor, you can always choose from a broad range of additional applications. If you use the CEBIS MOBILE on a tractor, you can connect an ISOBUS-compatible implement to the terminal and control it from the same terminal that you use for GPS control. Utilise your full yield potential by employing the CROP SENSOR to optimise N fertiliser application. You can also combine it directly with variable rate application (VRA) for precision farming work. If you don't need the terminal on the tractor at harvest time, you can transfer the GPS components to your LEXION or JAGUAR, enabling you to continue using the GPS PILOT. On the LEXION you can also make use of the CEMOS and optional CEMOS AUTOMATIC functions. CEMOS AUTOMATIC continuously adjusts residual grain separation and cleaning and thereby permanently optimises the machine for the prevailing harvesting conditions. As a result, the machine is able to automatically deliver maximum throughput while maintaining the highest standards of grain and sample quality and keeping fuel consumption to a minimum. 28

29 GPS PILOT CEBIS MOBILE. With ISOBUS. Description of the components. 1 GPS PILOT receiver: this high-precision receiver transfers the GPS position data to the terminal. 2 GPS PILOT terminal: the GPS PILOT terminal, working with the VDPM module, converts the GPS position data received into steering signals. 3 Gyro and steering valves: the gyro provides maximum compensation for longitudinal and lateral movements and relays the steering signals to the steering valves. GPS PILOT CEBIS MOBILE 29

30 The various driving modes automatic steering at a glance. A-B mode. The first pass is defined by setting the points A + B. All other passes are made at a constant distance defined by the set working width from the first pass. This means the field can be divided into blocks and worked through block by block. Contour mode. 1 The contour guidance function is normally used for headland turning or for tracking slightly curved field boundaries. 30

31 A-B contour mode. The A-B contour driving mode can be used, for example, to log a reference line on a slightly curved field boundary. The other passes are calculated by the parallel shifting of the reference line as defined by the set working width. This means the field can be divided into blocks and worked through in any order of preference. Circle mode. 2 The circular tracking mode is used for working in a circular pattern. You can set the first circular track and then work either side of it. All other passes are made at a constant distance defined by the set working width from the first track. A+ angle mode (reference track transfer). This driving mode allows tracking adjustment of several machines working in parallel. After the A point has been set, the B point is determined by the position angle of another machine and the reference track is correspondingly aligned. 1 Accuracy and speed are restricted with CEBIS MOBILE 2 Only available with GPS PILOT S3 Driving modes 31

32 A range of correction signals see page 51 EGNOS / E-DIF OMNISTAR XP / HP / G2 +/ cm 1 No licence fee Basic accuracy +/ 5 12 cm 1 Satellite-based correction signal Dual-frequency signal Subject to licence

34 EGNOS. Licence-free correction signal. EGNOS (European Geostationary Navigation Overlay Service) is available to users free of licence fees in many parts of Europe. It supplements GPS and uses 34 ground stations to generate the correction signal. EGNOS is available for all machines. With an accuracy of +/ 15 to 30 cm 1, it is ideal for many crop spraying, fertilising and soil cultivation applications see page 51

35 E-DIF. Available worldwide. E-DIF is an algorithmic calculation of the correction signals using only the GPS data. During the ten-minute initialisation period it calculates how the current satellite constellation will change over the next few hours. The signal is available worldwide. It must be receiving at least 4 satellites in order to work. This signal then provides the same accuracy as EGNOS (+/ 15 to 30 cm 1 ) and is therefore ideal for crop spraying, fertiliser spreading and tillage applications. When working in the field, it is only possible to drive from pass to pass; E-DIF cannot be used to establish blocks. If you have opted for the GPS PILOT with S3 or CEBIS MOBILE terminal with EGNOS, for example, you can upgrade your system at any time to a higher level of accuracy such as BASELINE HD. You then have a mobile reference station which can supply your machine fleet with the licence-free correction signal within a radius of up to 5 km. See page 37 for more details. 1 see page 51 EGNOS E-DIF 35

36 OMNISTAR HP / XP / G2. Unlimited working radius. OMNISTAR HP / XP / G2 operates in much the same way as EGNOS. However, this system is equipped with a dualfrequency GPS receiver, enabling it to achieve a far higher level of GPS accuracy. With 70 reference stations, it provides a continuously available correction signal service, subject to a subscription. The correction signal receiver is particularly quick to respond and achieves an accuracy of +/ 5 12 cm 1. 1 The machine receives signals transmitted by GPS satellites. 2 The machine additionally receives a high-precision correction signal (D-GPS) transmitted by a geostationary satellite. 3 The GPS PILOT converts both signals into steering signals. Tractors from CLAAS and other manufacturers can easily be retrofitted with OMNISTAR. The system is suitable for a wide range of agricultural applications. OMNISTAR HP can easily be extended to include, for example, RTK (Real Time Kinematic). RTK gives you dualfrequency receiver technology and high-precision performance with an accuracy of +/ 2 to 3 cm. See page 38 for more details. 1 see page OMNISTAR is installed on the machine only. There is no need for a reference station.

37 BASELINE HD. 1 The machine and BASELINE HD receive signals transmitted by GPS satellites. 2 The machine additionally receives a high-precision correction signal (D-GPS) transmitted by the mobile reference station via a radio signal. 3 The GPS PILOT converts both signals into steering signals. Mobile reference station. BASELINE HD is a reference station designed for mobile use. The system is unique on the GPS market and works to an accuracy of within 4 to 6 cm 1. BASELINE HD provides a proprietary correction signal at no extra cost. Another benefit is the fast start-up time. The signal can be used by numerous other machines. The integrated rechargeable battery lasts a full working day and is designed for long hours of work. BASELINE HD components. The mobile reference station comprises: GPS receiver and GPS antenna Radio and radio antenna Battery All components are integrated in the device. 1 see page 51 OMNISTAR HP / XP / G2 BASELINE HD 37

38 RTK. Stationary reference station. RTK is the right technology when every centimetre counts, e.g. for sowing or harvesting. The reference station is stationary and comes equipped with dual-frequency reception technology. It sends the correction signal to any number of machines operating with fully automated GPS steering systems within a radius of up to 15 km. All these machines then simultaneously achieve a high level of working precision. 1 The machine and the stationary reference station receive signals transmitted by GPS satellites. 2 The machine additionally receives a high-precision correction signal (D-GPS) transmitted by the reference station via radio signal. 3 The GPS PILOT converts both signals into steering signals. Best-in-class system providing many benefits. 1 Highest possible repeatable accuracy Fastest signal availability Maximum efficiency Superior operating comfort and convenience Lower operating costs in the long term Perfect for entire fleets Accuracy of 2 to 3 cm 1 see page The stationary RTK system comprises a control cabinet with receiver, power supply unit and radio. A GPS and a radio antenna are located in an elevated position, e.g. on a silo.

39 RTK NET. 1 The machine and the RTK network receive signals transmitted by GPS satellites. 2 The central server calculates a correction signal from networked reference stations. 3 The machine receives the high-precision RTK correction signal via the mobile phone network. 4 The GPS PILOT converts both signals into steering signals. Working independently. RTK NET extends the product range for regions where there is no access to a base station. The correction signals are sent via the mobile phone network. RTK NET is not constrained by a specific radius and is therefore the ideal solution for contractors and farms seeking to work with the highest repeatable precision. Like RTK, RTK NET uses dualfrequency technology 2-Frequenz-Technologie. The system features a very quick signal availability (initialisation) and a highest repeatable accuracy of +/- 2 3 cm 1. Working benefits. Correction signal via mobile phone network Access to existing RTK networks Unrestricted working radius Individual machine operation Highest possible repeatable accuracy Very quick signal availability 1 see page 51 RTK RTK NET 39

41 CAM PILOT LASER PILOT Optical steering systems

42 Advantages at a glance: Low purchase cost and accuracy of +/ 2 3 cm Low incidence of faults because the CAM PILOT does not need an external signal source Functionality of the CAM PILOT is guaranteed from a speed of 50 m/h Greater efficiency due to higher area output Capacity for higher working speeds 42

43 CAM PILOT. Looking ahead. The CLAAS CAM PILOT helps you harvest with fewer losses. The CLAAS CAM PILOT assumes the task of steering the new JAGUAR when the PICK UP is fitted, which means that working speeds of up to 15 km/h can be achieved without fatigue. What's more, the operator can focus more fully on filling up the trailer without crop losses. The CAM PILOT detects the swaths in three dimensions and this is automatically translated into the appropriate steering input. The CAM PILOT is also activated in the usual way by using the speed control lever, and is deactivated again whenever the steering wheel is turned. CAM PILOT 43

44 LASER PILOT. Don t waste a single centimetre. More performance and less strain. Automatic steering in grain crops significantly reduces the strain on the driver. This is especially true when using large cutterbars and operating at high speeds or in poor visibility. A maintenance-free sensor continuously transmits invisible light signals and moves horizontally at an angle of 6. The standing crop and the stubble reflect the light beam. A second sensor measures the travel time of the reflected light signals and thereby determines the exact position of the edge between the cut and uncut crop. The machine is automatically guided along this crop edge with a precision of 10 to 20 cm. LASER PILOT also achieves a high functional reliability in the case of laid grain and when working on slopes. 44

45 Your benefits at a glance. High functional reliability and safety regardless of visibility conditions Full utilisation of the cutterbar width at all times Reduced fuel consumption Increased seasonal performance Significant reduction in workload for the operator, enabling him to concentrate fully on the combining process LASER PILOT 45

47 AUTO PILOT Mechanical steering systems

48 Maintaining the optimum position. The AUTO PILOT system for combine harvesters and forage harvesters was the first steering system CLAAS launched on the market in The system has proven its effectiveness thousands of times over. The AUTO PILOT technology has undergone a continuous process of development and refinement throughout which numerous patents have been filed. Two mechanical touch sensors determine the position of the machine, send signals to the steering unit and automatically steer the machine through the crop. Maintaining the optimum position in all working conditions is the key to enhanced performance and higher efficiency. 48

51 Liability disclaimers, correction signals Please note that some variants are not available in every country. Please contact your distributor for further information. EGNOS is a service available free of charge in Europe. WAAS is a comparable service for North America. Please note that both systems may produce a shift in passes over time (satellite drift). These systems are not suitable for use in machine fleets (e.g. combine harvesting), or drilling operations. The accuracy data given relates to the accuracy of the GPS receiver on the machine under perfect conditions. All data is given as maximum values. A distinction is made between pass-to-pass accuracy and absolute accuracy. Pass-to-pass accuracy defines the accuracy of the subsequent pass in 95% of cases within 15 min of the reference track. Absolute accuracy defines at what level of accuracy a certain position can be found at a later time. The actual accuracy of the overall system can deviate from the abovementioned accuracy data. It depends on various influential factors such as vehicle factors (wheelbase, ballasting, calibration, etc.), attached implements (drift, configuration, attached front implements, etc.), and field and soil conditions. CLAAS assumes no liability for circumstances or events beyond its control. These may include, for example, disturbances in the atmosphere/ troposphere/ionosphere, breakdowns/disruptions or insufficient availability and shutdowns of satellites within global navigation satellite systems (GPS, GLONASS, GALILEO) and their ground reference stations as well as satellites belonging to correction service providers (EGNOS, OMNISTAR, etc.). E-DIF is patented correction algorithm which uses only standard GPS satellites to calculate a correction factor. E-DIF is therefore available worldwide as an alternative correction system in the basic accuracy segment and, within a few minutes, its accuracy is comparable with that of SBAS services (EGNOS, WAAS, etc.) for pass-to-pass applications. Therefore E-DIF should only be used for pass-to-pass tracking. E-DIF is completely unsuitable for driving in blocks or for use in controlled traffic applications or machine fleets (e.g. combine harvesting). It is also impossible to record points for absolute positioning. Shifts in tracks (satellite drift) due to long interruptions in work can be corrected using an update function (setting a reference point). The pricing of the respective services depends upon region and the respective provider. In the case of correction data services transmitted via mobile phone networks, use is dependent on the coverage of the respectively used network provider. Overview of steering systems 51
