[0032]Example
[0033]Such asfigure 1 The low power GPS positioning method, including the following steps:
[0034]S1: The GPS module of the base station gateway acquires local location information and local time information;
[0035]S2: The base station gateway interacts with the A-GNSS server to interact with the A-GNSS server, and the acquired real-time epicard information is about 6.3KB, which contains the GPS module and the BD epicardial data. The base station gateway is 1-2 hours. The AGPS server interacts.
[0036]S3: The wireless communication module of the base station gateway uses the FSK modulation method real-time broadcast overrides the achieved real-time epicardial and local location information, and local time information; because of the large amount of transmission data, the FSK modulation method is used, and the rate is up to 300kbit. It sends in the form of broadcast, uninterrupted polling transmission. The broadcast coverage area is up to 10 kilometers.
[0037]S4: The MCU of th...
