PC Clock synchronization using GPS. It can be used as NMEA and COM port tester. The program synchronizes a PC Clock to the right time using artificial satellites.

GPS component VB library toolkit reads and decodes standard GPS NMEA 183 sentences from the RS232 serial port, as well as computes great circle distances and bearings. Runs as a background thread unattended. Works with Visual Basic and VB.NET.

ZylGPSReceiverAX is an ActiveX control that communicates with a serial GPS receiver. This control works with any NMEA compatible receiver connected to one of the serial ports. You can use it also with USB devices.

ZylGPSReceiver is a Delphi/CBuilder component that communicates with a serial GPS receiver. This component works with any NMEA compatible receiver connected to one of the serial ports. You can use it also with USB and Bloototh devices.

HS GPS is a software library (with full C source code) which provides access to a NMEA-183 compliant GPS receiver via a serial communications port, decoding NMEA sentences: $GPGGA, $GPGSA, $GPGSV, $GPGLL, $GPRMC and $GPVTG.

GPS component C/C++ library toolkit reads and decodes standard GPS NMEA 183 sentences from the RS232 serial port, and computes great circle distances and bearings. Runs as a background thread unattended. Works with C++,VC.NET,C#,MFC,C++ Builder.

TimeTools GPS Clock Software is a freeware utility that runs on any Windows NT/2000/XP/2003 workstation or server. The software polls time from a standard NMEA GPS time receiver connected to the host PC''s serial port to sync PC time.

Use GPS without GPS receiver! This is software GPS device simulator (virtual GPS receiver). Generates NMEA messages from different data inputs (map or file). It can be used for development purposes or for testing GPS software and hardware.

ZylGPSSimulator is a Delphi GPS receiver simulator component. It creates a virtual serial port, converts the position parameters in NMEA format and writes them to the virtual port. The user can set parameters like latitude, longitude, altitude...

ZylNMEAGenerator is a Delphi component that transforms position data in NMEA format. You can generate complex NMEA sentences from simple data inputs. The sentences are recognized by any NMEA compatible mapping software.

Win/CE GPS client library component reads and decodes standard GPS NMEA 183 sentences from the RS232 serial port as well as compute great circle distances and bearings. Registration is $105 ($195 with source) for email delivery.

GPS Express provides a feature rich interface to serial NMEA-0183 protocol data and works with most NMEA-0183 devices, including GPS Receivers. GPS Express is available in three versions (Standard, Professional, Graphical)...
