JRC JLR-7700MKII (DGPS)

DGPS navigator JRC The JLR-7700MKII is a navigation receiver receiving information from satellites and issuing accurate coordinates of the ship's position on the basis of this data. 

The receiver can store in-memory detailed navigation information about 499 waypoints, as well as up to 100 event markers, which, if necessary, assigns eight-digit names. The device is equipped with built-in alarm, which will alert the user with a sound signal about arrival to the specified waypoint, drift, crossing the border or deviating from the paved course.

The receiver  JLR-7700MKII  provides several options for correction of coordinates: manual or by the standards of 46 available geodetic systems. The accuracy of determining the coordinates is: for the GPS system - 15 meters, for the DGPS - 5 meters.

The navigator is equipped with two RS-422 ports for connection to other devices and sensors. For the power supply of the device, an on-board network with a voltage of at least 10 volts is used.
