HsGpsDll is designed for use from Visual C, C++, Visual C Sharp .NET, Visual Basic or other programming languages, capable of calling DLL functions.

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).

GPS position fix obtained via HsGpsDll contains:

* Latitude coordinate in degrees, minutes, seconds and direction (South / North)
* Longitude coordinate in degrees, minutes, seconds and direction (East / West)
* Coordinates in decimal degree format
* Fix quality - valid or invalid
* Number of satellites in view
* Speed in kilometers per hour
* Altitude (Mean Sea Level)
* UTC date and time

The use of HsGpsDl Library is Royalty Free.

Features

* Interfaces a GPS receiver over COM ports COM1 - COMn (any port number can be used)
* To obtain GPS information, HsGpsDll decodes the following sentences of NMEA-183 (National Marine
Electronics Association, Interface Standard 0183:
- $GPGGA - geographical position fix data
- $GPRMC - Recommended minimum specific GPS data
- $GPVTG - velocity over ground"; function tShowHide(id, show) { var s = document.getElementById("desc"); if ((s.innerHTML.length<=212 || show==1) && show!=2) { s.innerHTML = fDesc[id]; if (document.getElementById('m1')) document.getElementById('m1').style.display='none'; if (document.getElementById('m2')) document.getElementById('m2').style.display='none'; if (document.getElementById('more_txt')) document.getElementById('more_txt').style.display='inline'; } else { s.innerHTML = ''; } }
