*Update rate depends on GPS update rate. 10ms Update rate shown corresponds to 100Hz GPS setting.
**Default Identifiers. The identifier values can be changed using the configuration software.
(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 = 1 Degrees, 58.82246 Minutes West). This is a true 32bit signed integer, West being positive.
(5) Velocity, 0.01 knots per bit.
(6) Heading, 0.01

per bit.
(7) Altitude, 0.01 meters per bit, signed.
(8) Vertical Velocity, 0.01 m/s per bit, signed.
(9) Status. 8 bit unsigned char. Bit 0=VBOX Lite, Bit 1=Open or Closed CAN Bus (1=open), 2=VBOX3
(10) Status is an 8 bit unsigned char. Bit 0 is always set, Bit 3=brake test started, Bit 4 = Brake trigger active, Bit 5 = DGPS active
(11) Distance, 0.000078125 meters per bit, unsigned. Corrected to trigger point.
(12) Longitudinal Acceleration, 0.01G per bit, signed.
(13) Lateral Acceleration, 0.01G per bit, signed.
(14) Distance travelled in meters since VBOX reset.
(15) Time from last brake trigger event. 0.01 Seconds per bit.
(16) Velocity at brake trigger point in Knots.
(17) Velocity Quality, 0.01 km/h per bit
