- If Satellites in view < 3 then only Identifier 0x301 transmitted and bytes 2 to 8 are set to 0x00.
- Time since midnight. This is a count of 10 ms intervals since midnight UTC. (5383690 = 53836.90 seconds since midnight or 14 hours, 57 minutes and 16.90 seconds).
- Position, Latitude * 100_000 (311924579 = 51 Degrees, 59.24579 Minutes North). This is a true 32 bit signed integer, North being positive.
- Position, Longitude * 100_000 (11882246 = 0 Degrees, 58.82246 Minutes West). This is a true 32 bit signed integer, West being positive.
- Velocity, 0.01 kts per bit.
- Heading, 0.01o per bit.
- Altitude, 0.01 meters per bit, signed.
- Vertical Velocity, 0.01 m/s per bit, signed.
- Status, unused.
- Status, unused.
- Longitudinal Acceleration, 0.01 g per bit, signed.
- Lateral Acceleration, 0.01 g per bit, signed.
- Distance travelled in meters since VBOX reset, 0.000078125 m per bit, unsigned.
