The GPS 112W now combines standard GPS positioning with the increased accuracy of WAAS. When the WAAS signal is used, accuracy is as low as 3 meters. Regular GPS accuracy is typically 5 meters. The GPS 112W is designed to plug directly into JRC radar and chart plotters for easy integration. The GPS 112W also has the ability to interface with any device that accepts NMEA data. Since it is a self contained sensor you can wire the GPS 112W directly to a computer, where it can drive your chart plotting programs. All you need to do is supply power to the sensor, so there is no need for an extra display.
