JLR-21
GPS satellite compass JLR-21 is used to provide information about the course, as well as to ensure high accuracy of traffic information. JLR-21 supports the SOG (Speed over ground) and COG (Course over ground). The provisions of SOG and COG are updated every 200 milliseconds (which is 5 times faster than the previous model JLR-20), ensuring high accuracy. GPS satellite compass JLR-21 provides a course of up to 0,5 °.
Display JLR-21 has a compact design and can be installed almost anywhere. The system of three antennas represented JRC, making it much more reliable than the conventional antenna system. The system has a short start-up time (less than two minutes). Maintenance for satellite JLR-21 compass is not required, making it less expensive to maintain.
