HsGpsDll is a Windows Dynamic Link Library which provides access to any NMEA-183 compliant GPS receiver via a serial communications port. HsGpsDll is designed for use from Visual C, Visual Basic or other programming languages. HsGpsDll allows a user application to easily read from a GPS device the current GPS position fix and current velocity over ground (speed in kilometers per hour), decoding sentences $GPGGA and $GPVTG.
