3.3 Function
As soon as the power on, the T-368 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 T-368 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 If significant inaccuracy exists in the initial data or the orbital data is
obsolete, it may take more time to achieve a navigation solution.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 T-368 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
4. Warranty
The GPS smart receiver is warranted to be free from defects in material and functions for one year from the
date of purchase. Any failure of this product within this period under normal conditions will be replaced at
no charge to the customers.
