  1. If Satellites in view < 3 then only Identifier 0x301 transmitted and bytes 2 to 8 are set to 0x00.
  2. Time since midnight. This is a count of 10ms intervals since midnight UTC. (5383690 = 53836.90 seconds since midnight or 14 hours, 57 minutes and 16.90 seconds).
  3. Position, Latitude * 100,000 (311924579 = 51 Degrees, 59.24579 Minutes North). This is a true 32bit signed integer, North being positive.
  4. Position, Longitude * 100,000 (11882246 = 0 Degrees, 58.82246 Minutes West). This is a true 32bit signed integer, West being positive.
  5. Velocity, 0.01 knots per bit.
  6. Heading, 0.01o per bit.
  7. Altitude, 0.01 meters per bit, signed.
  8. Vertical Velocity, 0.01 m/s per bit, signed.
  9. Status, unused.
  10. Status, unused.
  11. Longitudinal Acceleration, 0.01G per bit, signed.
  12. Lateral Acceleration, 0.01G per bit, signed.
  13. Distance travelled in meters since VBOX reset.
