  • VELOCITY_VALUES: bool bool bool bool bool bool bool …

    list of 11 boolean flags separated by whitespace for STR1 STR2 STR3 GPSR-A GPSR-B VCU-A VCU-B IMU-1 IMU-2 IMU-3 IMU-4

  • GPS_TIME: int

  • ORBIT_ANGLE: float

    orbit angle with respect to WGS-84

  • INNOVATION_STR1: float float float

    difference between GSE filter estimate and second in-use STR measurement

  • INNOVATION_STR2: float float float
