      Support Thread: Time Offset Between GPS Data and INS Data

      Customer:

      I have found one issue that I am currently confused with. The timestamp recorded from COM1 of the INS is consistently 17-20 seconds fast. If I start recording at 00 seconds, the first timestamp is equal to 17+ seconds, however the location data that comes from the GPS receiver is correct for 00 seconds and not 17+ seconds. Any insights into this issue?
