One of the main requirements coming from different clients is to add an "anti-theft alarm" function to our gps trackers, which will trigger the loud BEEP BEEP alarm whenever the motorcyc...
The principle of base station based positioning: Since each base station has its unique CID, the information in the engineering mode is stored in a specific area of the phone's memory each tim...
The mobile engineering mode, as the name suggests, refers to the mode of the mobile phone in the engineering testing state. It is designed for the engineering personnel or mobile engineers respons...
24 GPS satellites orbit the Earth at an altitude of 12000 kilometers above the ground in a 12 hour cycle, allowing for simultaneous observation of more than 4 satellites at any point on the ground...
The basic principle of GPS positioning is to use the instantaneous position of high-speed moving satellites as known starting data, and use the method of spatial distance resection to determine th...
Mobile phone positioning, hence its name meaning, is to determine the approximate target location of the holder by reflecting the base station code returned by the base station through the mobile ...
GPS (Global Positioning System) is the second generation Satellite navigation of the United States, which is a new generation of satellite navigation and positioning system with the capability of ...
For navigation and positioning, GPS satellites are dynamic known points. The position of the satellite is calculated based on the ephemeris (parameters that describe the satellite's motion and...
So it is necessary to check whether the GPS antenna is placed in an open environment and whether the GPS data output by the GPS module can be read? Can the GPS satellite signal status be observed ...
The GPS module is an integrated circuit that integrates RF RF chips, baseband chips, core CPUs, and related peripheral circuits. At present, the majority of GPS chips in GPS modules are mainly ba...
