The INS does not output a solution despite the GNSS having a fix, it says the INS is disabled, but I dont know how to enable it. Page 12 in the ICD might be a clue (Set Initial Heading)?

The GNSS was also unable to get a fix during WDR

This has been resolved. Turns out you have to run the VN300 with both antennas for the INS to function at all. Testing with both antennas yielded success, INS starts up in about 15 minutes.
