GPS Engine
A NEW 12 channel GPS Engine combining designed to provide OEM customers with high accuracy positional and tracking data. The GPS Engine interprets signals received from the GPS network of satellites that circle the earth to provide data on position, direction, altitude and speed.
The receiver interfaces via a RS232 interface or Uart. Data transfers across the interface to the application software by emulating a serial communication port on the SatNav GPS Receiver.
The SatNav Receiver is designed to be integrated with many end-product solutions, including personal applications, transportation, marine, aviation and industrial markets, although it is not limited to these markets. A sample of relevant applications are:-
Transportation - A GPS receiver can help drivers know exactly where they are and, with the right application software, where they are going.
Emergency - Special service markets such as border patrols and law enforcement agencies require pinpoint accuracy for added security and safety for individuals in a wide variety of remote areas. The GPS Engine, with the appropriate mapping application, will provide the tools need to respond quickly.
