3.3 Function
As soon as the power on, the SG-288 Bluetooth GPS receiver begins the process of satellite acquisition,
tracking, and Bluetooth radio connection.
Under normal circumstances, it takes around 42 seconds
(average) to achieve a position fix at the first time.
After a position fix has been calculated,
information about valid position, velocity, and time is transmitted over the output channel.
The SG-
288 Bluetooth GPS receiver utilizes initial data, such as last stored position, date, time and satellite
orbital data, to achieve maximum acquisition performance.
If significant inaccuracy exists in the
initial data or the orbital data is obsolete, it may take more time to achieve a navigation solution.
3.4 Navigation
After the acquisition process is complete, the SG-288 Bluetooth GPS receiver sends valid navigation
information over output channels.
These data include:
1) Latitude/longitude/altitude
2) Velocity
3) Date/time
4) Error estimates
5) Satellite and receiver status
