GPRS Tracking Report Syntax :
Real time GPS Data Report format:
$RGTK,[UnitID],[UTCTime],[A|V],[Longitude],[E|W],[Latitude],[N|S],[Satellite
Numbers],[GSM Signal],[Angle],[Speed],[Mileage],[AI1],[AI2],[DI],[DO],[RTCTime]&
Resent format: (When the GPRS is recovered, the tracker will resend all GPS data logs
to the Gateway Server automatically.)

Field
Description
Event Type
Event Type
UnitID
UnitID
UTC Time
GPS Date and Time.
The format is DDMMYYHHmmss
A|V
GPS Data is Valid or Invalid. “A” = valid, “V” = invalid.
Longitude
GPS Longitude
E/W
“E”= East, “W” = West.
Latitude
GPS Latitude
N/S
“N” = North, “S” =South
Satellite Numbers Satellite Numbers acquired. The maximum satellite number is 12.
Normally the SiRF Star III can receive about 6~8 satellites if the
GPS antenna is in the open sky.
GSM Signal
GSM Signal strength, From 0 to 31, Unknown: 99 or other numbers
The maximum GSM signal is 31. Normally it should be more than
20. If it is less than 20, it means poor GSM reception of OBDtrac in
that particular area. Try to adjust the location of GSM Antenna for a
stronger GSM signal
Angle
GPS Angle, unit = degree
Speed
GPS Speed, unit = knot
Mileage
Accumulated Mileage of the tracker. It is calculated by GPS data.
Unit = ‘mile’. Maximum value: 999999.99
