This program is a demo application for BitLevelGPS software library that provides a PC-based user application with access to a NMEA-183 compliant GPS receiver via a serial communications port. It provides navigational data update once per second, decoding NMEA sentences: $GPGGA (Global Positioning System Fix Data), $GPGSA (DOP and Active Satellites), $GPGSV (Satellites in View), $GPGLL (Geographic position), $GPRMC (Recommended Minimum Specific GNSS Data) and $GPVTG (Course over Ground and Ground Speed). Decoded parameters include: UTC time, date, position (lattitude, longitude), altitude, speed, course, heading and information about visible satellites. Applications include Navigation, Security, Telematics, Fleet Tracking and Asset Tracking. The library provides an interface over serial ports COM1 - COM8.
