B. Operational characteristics

B.1 Initialization

After you place the battery into the housing, and put the switch at ON or AUTO, then the BT-Q880 is ready to

work for you. When you activate the Bluetooth function in your machine (PDA or PC) and get pairing with

BT-Q880, you may start GPS function. As soon as the initial self-test is complete, the BT-Q880 begins the

process of satellite acquisition and tracking automatically. Under normal circumstances, it takes approximately

30 seconds to achieve a position fix at the first time, 30 seconds if ephemeris data is known. After a position fix

has been calculated, information about valid position, velocity and time is transmitted over the output channel.

The BT-Q880 utilizes initial data, such as 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 If significant inaccuracy exists in the initial data, or the orbital data is obsolete, it may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. The BT-Q880 Auto-locate feature is capable of automatically

determining a navigation solution without intervention from the host system.

B.2 Navigation

After the acquisition process is complete, the BT-Q880 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
