LTN-2012 Global Navigation Satellite System (GNSS)
Designed for the commercial aviation industry, Northrop Grumman’s LTN-2012 Global Navigation Sensor System (GNSS) is a twelve channel, L1 CA Code, continuously tracking ARINC 743 GNSS sensor. The LTN-2012’s intelligently designed growth path will help operators reduce installation and certification costs. Future applications include curved path approaches, CAT 1 approaches, and reduced minimums for non-precision approaches.
The LTN-2012 has been developed to meet RTCA 178B Level B, RTCA DO-208, and RTCA DO-217 (SCAT-1) requirements to allow for FAA certification by OEM integrators. The LTN-2012 operates in automonous and differential modes, making it useful for all phases of flight, including precision approach. It also features RF interference resistance.
The LTN-2012 is integrated with various airborne navigation equipment and has demonstrated excellent performance in flight tests conducted by ground reference station manufacturers.
