JRC JLR-7600 / JLR-7900

The JRC JLR-7600 and JLR-7900 global navigation satellite receiver (GNSS) receivers are designed for use on ships with a maximum speed not exceeding 70 knots.

The receiver consists of a GPS antenna and a control unit. Depending on the modification, the antenna JLR-4340 (GPS) or JLR-4341 (DGPS) is supplied. As a control unit in both cases, the NWZ-4610 is supplied, which has a 4.5-inch display, a modern stylish design, and is an excellent addition to the ship's navigation system.

The JLR-4340 (GPS) receiver provides high accuracy in determining ship coordinates using up to 12 satellite signals. The JRC GPS receiver combines the DGPS measurement with the correction data transmitted from the SBAS satellites (WAAS, EGNOS, MSAS), resulting in a higher accuracy of the current position.

The NMEA0183 output can be configured as version 1.5.2.1 or 2.3, which allows data to be transferred to ship equipment of various types, including radar, fishing and plotters.
