SharpGPS - GPS library for .NET
SharpGPS is a GPS library for .NET 2.0 and .NET 2.0 Compact Framework. It supports parsing of NMEA, relaying raw RTCM data either through custom protocol, or via NTRIP for enhanced accuracy. There is no depencency on Windows Mobile’s GpsApi, so this framework supports any device that runs either the full .NET Framework 2.0 or the .NET Compact Framework 2.0. This makes it easy to reuse your code across all platforms.
