The GPS-1200 is a miniature GPS receiver module, suitable for a direct connection to a computer (for example a laptop), to provide fast and cost-efficient GPS implementation.

The receiver comes in two versions, a USB interface version (GPS-1200-U) and a serial interface version (GPS-1200-S). The tiny receiver contains its own antenna, and derives its power from the host computer interface. A CD ROM with drivers for Windows 95, 98, ME, 2000 and XP is supplied for the USB version. The serial interface version does not require any drivers. The output format complies with the NMEA0183 standard, making it compatible with most popular mapping software, for example Microsoft Streets and Trips as well as with field strength measurement applications, such as WiNRADiO Field Strength Logger.

GPS-1200 for vehicle navigation

The GPS-1200 waterproof package has a strong non-slip magnetic base,
and is ideally suited for placement on the roof of a vehicle.
