ROVERPOS

Position using ALIGN

Platform:

OEM719, OEM729, OEM7500, OEM7600, OEM7700, OEM7720, PwrPak7, CPT7, CPT7700, SMART7

ALIGN generates distance and bearing information between a base and rover receiver. This log outputs the position information of the rover when using the ALIGN feature. This log can only be output from a Y ALIGN model and can be output at both Base and Rover ends.

You must have an ALIGN capable receiver to use this log.

 

  • ALIGN is useful for obtaining the relative directional heading of a vessel/body, separation heading between two vessels/bodies, or heading information with moving base and pointing applications.

  • The log can be output at the Y model Rover only if it is receiving the RTCAREFEXT message from the Base. The log can be output at any Base if the Base is receiving HEADINGEXTB from the Rover.

  • ROVERPOS is dependent on the output frequency of the RTCAREFEXT message from the base to the rover.

  • On dual antenna receivers, the ROVERPOS log outputs the position for the secondary antenna input.

ASCII Example:

#ROVERPOSA,COM1,0,21.5,FINESTEERING,1544,340322.000,02000008,7453,4655;SOL_COMPUTED,NARROW_INT,51.11605565964,-114.03854655975,1055.8559,-16.9000,WGS84,0.0130,0.0122,0.0206,"RRRR",0.0,0.0,13,12,12,11,0,0,0,0*635b3a1c

Asynchronous logs, such as ROVERPOS, should only be logged ONCHANGED or ONNEW, otherwise the most current data is not output when it is available. This is especially true of the ONTIME trigger, which may cause inaccurate time tags to result.
