INSPVA

INS Position, Velocity and Attitude

Platform: 

OEM719, OEM729, OEM7500, OEM7600, OEM7700, OEM7720, PwrPak7, SPAN CPT7, SMART7-S, SMART7-SI

Firmware Stream:     

This log allows INS position, velocity and attitude, with respect to the SPAN frame, to be collected in one log, instead of using three separate logs. Refer to the INSATT log for an explanation of how the SPAN frame may differ from the IMU enclosure frame.

This log provides the position information in WGS84.

Message ID: 507

Log Type: Synch

Recommended Input:

log inspvaa ontime 1
