Program a Windows Mobile GPS Device using the Intermediate Driver

A couple weeks back I was highly influenced by a small-map-based GPS (Global Positioning System) application, developed using C#, targeting windows mobile devices. Embedded GPS receivers are becoming a standard for mobile devices, and all recent Windows Mobile devices feature GPS receivers. Windows mobile users can also add third-party GPS receivers to their devices if needed.

These GPS receivers collect data from satellites, specifically latitude, longitude, altitude, speed, and direction data from four different satellites. Mobile GPS receivers refresh collected data every second and display your present location on the Microsoft MapPoint, a powerful data-mapping tool. Your location is calculated using a mathematical formula called three-dimensional trilateration, which uses the positions of the satellites and their distance from Earth. Read the full article.

Windows Mobile: Working with FakeGPS

Microsoft has introduced a new tool named FakeGPS for Windows Mobile application developers and testers. Testing GPS application was difficult in earlier mobile SDK versions as a GPS receiver doesn't work within closed walls, also the Emulators didn't have any GPS simulated testing tool built in. Using FakeGPS, developers and testers can now easily simulate satellite based global positioning system data and use that for testing their GPS applications. FakeGPS comes with Microsoft Windows Mobile SDK v6.0 and DTK version 6.3.5; after the SDK installation FakeGPS.cab is copied into C:\Program Files\Windows Mobile 6.5.3 DTK\Tools\GPS folder.
