GPS data on M2M Modules

Device manufacturers implement proprietary AT coommand interfaces for GPS functions. General controls are enable/disable GPS, set GPS mode (standalone, MS-Assisted etc) and get GPS data.

GPS Testing for Huawei Modules
In the ‘GPS’ tab of AT Command Tester, the GPS feature of Huawei modules can be tested.
Huawei modules supports different kind of GPS modes such as standlone, MS-Assisted, MS-based and gpsOneXTRA. Use can set the specific mode. Once the ‘Start Positioning’ button is presssed, the module will acquire the GPS position. Based the the GPS mode configured, the acquisition could vary and could take up to a minute. Once the GPS position is available, GPS information (latitude, longitude, altitude) will be automatically populated in the corresponding fields. If the GPS information is available, the ‘Show Map’ button will open the Google maps in a browser with the avaialble GPS coordinates.
