R4 NAVIGATION SYSTEM

Computer Engineering electronics Engineering Civil Engineering

The R4 Navigation System is available in two configurations: GPS and DGPS. Both configurations feature an R4 Display. The GPS configuration also features an R4 GPS Navigation Sensor and an MGA-2 GPS antenna, while the DGPS configuration features an R4 DGPS Navigation Sensor and an MGL-4 combined GPS/Beacon antenna. The R4 Display provides a graphical interface to the system. Via the display it is possible to create, edit and modify routes and waypoints, navigate following a route, plot the route, view sensor data, perform setup as well as supervise the systems status. The R4 GPS Navigation Sensor features a high-precision GPS receiver, capable of receiving WAAS, EGNOS and MSAS differential corrections. The R4 DGPS Navigation Sensor has all the features of the GPS Sensor, as well as a dual channel beacon receiver for reception of IALA radio beacon DGPS corrections. The R4 Navigation Sensor is connected to the antenna, either an MGA-2 GPS antenna or an MGL-4 combined GPS/Beacon antenna. The MGL-4 antenna is capable of receiving and interpreting both radio beacon and satellite signals. Together the R4 Display and the R4 Navigation Sensor provides three configurable serial user ports, of which two are bidirectional and one used only for output of data. There are also a binary Speed Log and an Alarm Output port, as well as an Alarm Acknowledge input port. 1.2 Main Features loading..
