The INS solution is available in the INS specific logs with either a standard or short header. Other parameters are available in the logs shown in Table 6, Solution Parameters:

Table 6: Solution Parameters

	Parameter		Log
Position		INSPOS or INSPOSS		INSPOSX or INSPVAXa
		INSPVA or INSPVAS
Velocity		INSVEL or INSVELS		INSVELX or INSPVAXa
		INSSPD or INSSPDS
		INSPVA or INSPVAS
Attitude		INSATT or INSATTS		INSATTX or INSPVAXa
		INSPVA or INSPVAS
Solution Uncertainty		INSCOV or INSCOVS

a.These logs contain variance information and are therefore large logs. Use a low logging rate (<20 Hz) only.

The position, velocity and attitude are available together in the INSPVA and INSPVAS logs.

The inertial solution is available up to a rate of 100 Hz. Data can be requested at a specific rate up to the maximum IMU output rate or can be triggered by the mark input trigger at rates up to 20 Hz.

The GNSS-only solution is still available through the GNSS-only logs such as RTKPOS and PSRPOS. When running SPAN-CPT, rates of non-INS logs should be limited to a maximum rate of 5 Hz. Refer to the OEM6 Family Firmware Reference Manual (OM-20000129) for more details on these logs. INS-only data logging and output can be at rates of up to the rate of the IMU data.

The highest rate to request GNSS logs (RANGE, BESTPOS, RTKPOS, PSRPOS and so on) while in INS operation is 5 Hz. If the receiver is not running INS, GNSS logs can be requested at rates up to 20 Hz.

the SAVECONFIG command to save settings in NVM. Otherwise, unnecessary data logging occurs and may overload the system.Ensure all windows, other than the Console, are closed in NovAtel Connect before using

Specific logs need to be collected for post-processing (see Data Collection for Post-Processingon page 33).
