**Default Identifiers. The identifier values can be changed using the configuration software.
- If <3 satellites in view, 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.
- Speed, 0.01 kts per bit.
- Heading, 0.01° per bit.
- Altitude above mean sea level based on the WGS 84 model of the earth, 0.01 m per bit, signed.
- Vertical Velocity, 0.01 m/s per bit, signed.
- Longitudinal Acceleration, 0.01 g per bit, signed.
- Lateral Acceleration, 0.01 g per bit, signed.
- Position, latitude 48 bit signed integer, latitude * 10,000,000 (min). North being positive.
- Solution Type, 8 bit unsigned integer, 0=No solution,1= Stand alone, 2= Code differential, 3=RTK Float, 4=RTK Fixed.
- Position, longitude 48 bit signed integer, longitude * 10,000,000 (min). East being positive.
- GPSDayH, unsigned char, most sig byte day number since 6th Jan 1980.
- GPSDayL, unsigned char, least sig byte day number since 6th Jan 1980.
- Diff Age, unsigned char, (s) differential age (0xFF = invalid).
- Serial Number, 20 bit, VBOX serial number.
