Leica Geosystems has added a new product to its line - a "smart" DGPS antenna - providing accurate position and velocity inputs to a laptop, or other system.
A single integrated unit, apMK31 is comprised of a 12-channel GPS receiver and two-channel beacon DGPS receiver - all sealed in low profile weatherproof fiberglass radome. Automatically receiving signals from GPS satellites and differential error correction data from marine radiobeacon broadcasts, apMK31 calculates the vessel's position within 3- 10 ft. (1-3 m) and outputs data once per second in the standard NMEA-0183 format.
