INSPVAS	INS solution	position, velocity (NEU), attitude (RPY), ins_status
INSCOVS	INS covariances	pos_cov[9], att_cov[9], vel_cov[9]
RAWIMUS	Raw IMU data	accel_x/y/z, gyro_x/y/z (raw counts)
MARKPOS	Position at mark event	Same fields as BESTPOS
MARKTIME	Time at mark 1 event	week, week_seconds, clock_offset
MARK2TIME	Time at mark 2 event	week, week_seconds, clock_offset
IONUTC	Ionosphere/UTC params	alpha/beta coefficients, leap seconds
RAWEPHEM	Raw GPS ephemeris	subframe1[30], subframe2[30], subframe3[30]
RXSTATUS	Receiver status	error codes, status words
