Page 10: Function
SG-288 Manual V1.1 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. -
