HsGpsDll
Library (NMEA 183)
Windows Dynamic Link Library which
provides access to a NMEA-183 compliant GPS
receiver via a COM port. Designed
for use from Visual C, 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 in degrees, minutes, seconds and direction (South / North)
* Longitude 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
To obtain the above information, HsGpsDll decodes the following
sentences of NMEA-183 (National Marine Electronics Association,
Interface Standard 0183:
* $GPGGA - geographical position fix data
* $GPRMC - minimum recommended fix data
* $GPVTG - velocity over ground
The demo application shows current GPS location on a map provided over
internet connection (if available) from Google Maps map server. The map
zoom level is adjustable from 16 to 0. The map is updated every 10
seconds if the coordinates of GPS receiver change.

* COM port to TCP/IP (TCP server mode)
* COM port to UDP
* TCP/IP client to UDP
* TCP/IP server to UDP
* TCP/IP server to TCP/IP client
* UDP to UDP
* Up to 32 links each interconnecting 2 ports in any combination shown
above are able to operate concurrently

* Forward instantly on data receive
* Forward on buffer full
* Forward on inter-character timeout
* Forward on frame end character
Diagnostic and Statistics Functions:
* Port status display
* Port receive and transmit byte counters
* Event log displayed on screen and saved to disk file
* Data traffic trace in ASCII or HEX format displayed and saved to disk
file
* Data traffic echo function (port loopback)
