42 Notes: If set to, GLONASS measurements are processed in the navigation filter for SPP and RTK send heading Description: Enables SBP heading output. Heading is calculated from base station to rover and represents the inverse tangent of the north and east components of the baseline solution send heading boolean, Table : send heading Notes: No smoothing or additional processing is provided to improve heading output. The heading feature requires the following additional settings Time Matched Mode Equal Observation rate between both base and rover The observation rate will also determine the heading output rate and is defined as soln freq / output every n obs output every n obs Description: Integer divisor of solution frequency for which the observations will be output solution output every n obs 2 integer None Table : output every n obs Notes: For instance, if the solution frequency (soln freq) is 10 Hz, and the output every n obs setting is 10, it means that the observation output will occur at a rate of 1 Hz. Since the observations are the information used by the Piksi receiving corrections from the connected Piksi, this determines the rate of information sharing for RTK solution output. This parameter is designed to tune the rate at which correction information is passed from one Piksi to the other as to efficiently use radio modem bandwidth and fit with user applications. Version v1.2.14, October 25,

43 disable raim Description: Receiver Autonomous Integrity Monitoring solution disable raim None boolean, Table : disable raim Notes: If, RAIM checks will not be performed heading offset Description: Rotate the heading output solution heading offset degrees None double Table : heading offset Notes: Adds an offset to the heading output to rotate the heading vector to align the baseline heading with a desired 0 heading. Valid values are to degrees elevation mask Description: SPP / RTK solution elevation mask Version v1.2.14, October 25,

44 solution elevation mask degrees 10 float None Table : elevation mask Notes: Satellites must be above the horizon by at least this angle before they will be used in a solution dgnss solution mode Description: Selects the of RTK solution to output solution dgnss solution mode Low Latency enum Low Latency, Time Matched, No DGNSS Table : dgnss solution mode Notes: A Low Latency solution uses an internal model of anticipated satellite observations to provide RTK output with minimal latency but slightly reduced accuracy. Low Latency mode assumes that the base station is stationary. For applications where accuracy is desired over timeliness or when both Piksi s are moving, Time Matched mode can be chosen. This means that the RTK output will require a corresponding set of correction observations for each timestamp. When No DGNSS is chosen, no differential output will be attempted by Piksi soln freq Description: The frequency at which a position solution is computed Version v1.2.14, October 25,

45 solution soln freq Hz 1 integer None Table : soln freq Notes: None correction age max Description: The maximum age of corrections for which an RTK solution will be generated solution correction age max seconds 30 float None Notes: None 3.22 standalone logging file duration Description: Duration of each logfile Table : correction age max standalone logging file duration minutes 10 int Table : file duration Version v1.2.14, October 25,

If this setting is changed while logging is enabled, it will go into effect immediately which will close the current file if its length exceeds the new duration max fill Description: Maximum storage device usage standalone logging max fill percent 95 int Table : max fill Notes: Sets a limit on how full the storage device can be before logging is stopped. If the drive is more than this percent full, no new log files will be created and a warning will be logged every 30 seconds. If this setting is changed while logging is enabled, it will go into effect on the next file that is created enable Description: Standalone logging enabled standalone logging enable boolean Table : enable Notes: Setting this to true triggers the logger to start trying to write logs to the output directory. Setting this to false will immediately close the current file and stop logging. Reenabling logging will increment the session counter which is reflected in the log file s (see USB Logging File Output section) output directory Description: Standalone logging path Version v1.2.14, October 25,

47 standalone logging output directory /media/sda1/ string Table : output directory Notes: Sets the paths in which to write logs. A warning will be logged every 30 seconds if this path is invalid or unavailable. The system will not create a folder that does not exist. If this setting is changed while logging is enabled, it will go into effect on the next file that is created surveyed position broadcast Description: Broadcast surveyed base station position surveyed position broadcast None boolean, Table : broadcast Notes: This flag ultimately determines whether the SBP message with identifier MSG BASE POS ECEF will be calculated and sent. Logically, setting this attribute to true sets the Local Piksi as a base station and configures the unit to send its surveyed position coordinates to the other Piksi(s) with which the base station is communicating. If true, the remote Piksi that receives the surveyed position will calculate and communicate a pseudo absolute RTK position based upon the received position surveyed alt Description: Surveyed altitude of the Piksi s antenna Version v1.2.14, October 25,

48 surveyed position surveyed alt meters 0 Double None Table : surveyed alt Notes: This setting represents the altitude of the Piksi s antenna above the WGS84 ellipsoid, in meters. If surveyed position broadcast is set to true, this coordinate will be communicated to remote Piksis for use in calculating their pseudo-absolute position. This value should be precise to 1 cm. Any errors in the surveyed position will directly affect the pseudo-absolute RTK position measurement reported by the Rover surveyed lat Description: Surveyed latitude of the Piksi s antenna surveyed position surveyed lat degrees 0 Double None Table : surveyed lat Notes: This setting represents the latitude of the local Piksi s antenna, expressed in decimal degrees relative to the equator (north = positive, south = negative). If surveyed position broadcast is set to true, the coordinate will be communicated to remote Piksis for use in calculating their pseudo-absolute RTK position. The value should be as accurate as possible and should have precision to at least 7 digits following the decimal point. For reference, 1e-7 degrees of latitude is about 1.1 cm on the surface of the earth. Any errors in the surveyed position will directly affect the pseudo-absolute RTK position measurement reported by the remote Piksi surveyed lon Description: Surveyed longitude of the Piksi s antenna Version v1.2.14, October 25,

49 surveyed position surveyed lon degrees 0 Double None Table : surveyed lon Notes: This setting represents the longitude of the local Piksi s antenna, expressed in decimal degrees relative to the Prime Meridian (east = positive, west = negative). If surveyed position broadcast is set to true, the coordinate will be communicated to remote Piksis for use in calculating their pseudo-absolute RTK position. The value should be as accurate as possible and should have precision to at least 7 digits following the decimal point. For reference, 1e-7 degrees of longitude at 35 degree latitude is about 1 cm.
