2 Relay RTK Module GPS 6500 RTK Relay 400/900 AutoBase with Saved Locations GPS 6500 RTK Relay v6.7 - AutoBase Autobase will allow users to save up to 32 positions in memory. The positions can be automatically saved after a self-survey or entered manually one-by-one and saved until all 32 locations are filled. The user will not be able to individually delete specific positions, but will be able to clear all positions from memory. There is no way to recover previously saved coordinates once all positions have been cleared from memory. Users should always record base positions for safe keeping after completing a 24hr survey. The positions will be sorted in order of use with the last active position at the top of the list. This will effectively order the positions by age. Once all 32 positions are filled, any further save of a new position either in MANUAL or AUTO mode will overwrite the oldest position. The "AutoSave the position to Memory" button on the AUTO tab have been added to prevent accidental overwriting of any saved positions in the case where all 32 positions used. If the user saves a new position in the MANUAL tab, the oldest position will be overwritten with the new one. After an initial auto survey is performed (first time out of the box), the unit will always perform an Auto Survey after each subsequent power up. It is no longer required to leave the Position menu set to the AUTO tab before shutting down. Jump to a section below: Automatic Survey With Auto Position Save Setting a Fixed Position Saving Fixed Positions Use Case 1: Self-Survey With Auto Position Save The user will go into the Position menu and select the AUTO tab.

3 Users can now select a survey time and accuracy level to be reached for the auto survey. When the Start button is pressed one of two things will happen:. 1. If the current location is within the tolerance of any location saved in memory, it will use that saved position as the reference location and stop the auto survey. 2. If the location is new and is not within the 4 meter tolerance of any previously saved location, it will complete the auto survey and then use that position as its reference location. The location will not be saved to one of the 32 available memory spaces unless the "AutoSave the position to memory" option was selected. The default tolerance for an Auto Survey position is fixed at 4m. When the user powers up the unit again, the receiver will perform an Auto Survey and if the current position is within the tolerance of any saved position, the co-ordinates of the saved position will be used as the base station co-ordinates. If the current position is outside the 4 meter tolerance any saved position, the Auto Survey will complete and the new position will be used as the base station co-ordinates. Use Case 2: Setting a Fixed Position The user selects the MANUAL tab and manually enters the position of the reference station in the latitude, longitude and altitude fields. The user also selects the checkbox "Use this as fixed position" and presses SAVE. Checking the box will immediately fix the position in the base station and save it. If this check box is not selected the position will only be saved into the next free memory location but this position will not be used as the reference location. If the check box is on and the current position is outside of the tolerance of the position entered, an INVALID FIX message will be displayed after the save.

4 Alternatively, if the user forgets to check the box and saves the position, then select the AUTO tab and press the START button. If the current position is within the tolerance specified of any position saved in memory, the auto survey will terminate quickly and use the saved position. If the current position is outside of the tolerance of any saved position, the Auto Survey will complete and the new position will be used as the base station co-ordinates. When the user powers up the unit again, the receiver will perform an Auto Survey. If the current position is within the tolerance of any saved position, the co-ordinates of the saved position will be used as the base station co-ordinates. If the current position is outside of any saved position, the Auto Survey will complete and the new position will be used as the base station co-ordinates. Use Case 3: Saving Fixed Positions The user selects the MANUAL tab and enters co-ordinates and a tolerance for each known base station and presses SAVE. The tolerance value defines a horizontal radius for which the receiver can be located away from the specified co-ordinate. If the current position at startup is within that radius of the saved position, the saved position will be used as the base station co-ordinate. Up to 32 positions can be pre-saved. The number of positions saved/total is displayed so the user can keep count. GPS 6500 RTK Relay 400/900 AutoBase with Saved Locations 3

5 The user cannot edit or delete individually saved positions, he can only BULK delete them using the CLEAR ALL POSITIONS button. A second prompt will be generated to confirm the deletion. Note: There is no way to recover previously saved coordinates once CLEAR ALL POSITIONS had been performed. Users should record all base positions for safe keeping after completing a 24hr survey. At startup, the receiver will always perform an Auto Survey. If the current position is within the tolerance of any saved position, the co-ordinates of the saved position will be used as the base station co-ordinates. If the current position is outside of any saved position, the Auto Survey will complete and the new position will be used as the base station co-ordinates.

The GPS 6500 is the only receiver that will work with the Relay. Q: Is the GPS 6000 compatible with the RTK Relay Module? 5

7 What is GLIDE? GLIDE is a positioning algorithm that provides superior pass to pass accuracy (over 15 minute durations) in environments where a differential signal is not available. GLIDE works globally, independent of correction signals such as WAAS or EGNOS, so it provides a stable signal for customers in Eastern Europe, Australia and South America. Additionally, GLIDE is focused on providing excellent service in areas of high ionospheric disturbance. On the scale of correction source accuracy, GLIDE is positioned above Autonomous pass to pass but below differential solutions such as WAAS and EGNOS. GLIDE absolute accuracy with the GPS 6500 is improved over the GPS 6000's GLIDE operation because the GPS 6500 has dual frequency capabilities. What is GLIDE? 6

19 What does "Received Release from BS" mean? GPS 6500 with CDMA RTK Relay Received release from BS message will appear on Ag Leader displays after unsuccessfully attempting to activate the GPS 6500 RTK Relay Cell modem. What this means: 1. CDMA RTK Relay is not accessing a Verizon tower. User will need to move closer to or locate a Verizon tower in order to activate CDMA Relay. When activating a CDMA Relay, it must be communicating with a Verizon tower. If communicating with a non-verizon tower, the plan will not initialize. Once the plan is active, the CDMA Relay will connect to any non-verizon towers that Verizon has roaming agreements with. Verify Verizon coverage for your area by visiting Search for Coverage Locator Select the "Data Coverage" button and refresh the map Confirm you are inside the 3G or 1x Data Coverage area To review the complete CDMA Relay activation guide, click here.

22 How to improve RTK Radio Signal reception with 400MHz relay and GPS The 400MHz relay for the GPS6500 is shipped with a wideband Radio antenna MHz, this antenna can be used in area's which uses a frequency within the 4xx MHz range. Advantage of this wideband antenna is it's combining good signal reception on a wide range of MHz frequencies and it's small length. Were used: PN ROVER BUNDLE - RELAY 400 MHZ & RTK UNLOCK Optimize for specific Frequencies: In areas where signal reception is more difficult, more specific MHz range antennas can increase signal reception in combination with the 400MHz relay. Ag Leader can offer the following specific range antenna's in the 400MHz range: PN ANTENNA MHZ 5DB NGP PN ANTENNA MHz 5DB NGP PN ANTENNA MHz Or you can source your frequency specific antenna locally. Fine Tuning antenna If using a MHz whip antenna, the antenna must be cut to the proper length to fine tune the frequency the radio will be using. 1. Refer to one of the tables 1, 2 or 3 to ascertain the proper length for the antenna and frequency being used. 2. Loosen the two set screws at the base of the antenna using a 3/32" Allen wrench, and then remove the antenna from the base. 3. Measure the antenna and mark the proper length using the diagram next to the table as a guide. 4. Cut the end of the whip with a hacksaw.

23 Reinstall the whip on the antenna base and tighten the two set screws. Ensure that the whip fits all the way into the base before tightening. Content last reviewed on: 6/1/18 Reviewed by: LM How to improve RTK Radio Signal reception with 400MHz relay and GPS

24 What is StableLocâ? StableLocâ is a feature that allows for increased run-time by utilizing all available correction sources for seamless machine guidance operation. As an example, if the RTK signal is lost, StableLoc will transition to the next highest accuracy correction source for the best pass to pass performance. When RTK correction is regained, StableLoc will smoothly transition back to the RTK guidance line. StableLoc will transition down to the next highest GPS correction source available - from RTK to WAAS down to GLIDE and seamlessly back for continuous operation and best pass to pass accuracy. Through testing, running with StableLoc enabled has shown enormous promise keeping differential correction in areas with compromised satellite constellation view (e.g. trees, buildings and other vertical obstructions) and has also shown improved pass to pass accuracy (vs. StableLoc disabled) while running on WAAS/EGNOS corrections. Users are encouraged to have StableLoc enabled when using WAAS/EGNOS. As stated above, through testing, having StableLoc enabled has shown promise to reduce the amount of WAAS/EGNOS drift and position jumps seen in field. In a WAAS/EGNOS scenario StableLoc helps to lock the signal using the GLIDE algorithm. It does not fallback to a GLIDE or Autonomous signal but rather GLIDE is used in conjunction with WAAS/EGNOS to prevent jumping when there is increased interference. To enable StableLoc, see display operator's manual. Content last reviewed on: 7/2/2018 Reviewed by: CG What is StableLocâ? 23
