The LN-120G is a Stellar-Inertial-GPS navigation system that provides precise navigation and sensor pointing with or without GPS. This system integrates stellar tracking and SAASM (Selective Availability Anti-Spoofing Module)-based GPS with a Zero-Lock™ Gyro (ZLGTM) inertial system to provide a highly accurate airborne true heading source. For critical reconnaissance missions, the LN-120G uniquely provides the precision heading and superior navigation performance necessary for modern weapons systems in GPS-denied environments. The LN-120G heading output is accurate to less than 20 arc seconds providing a greatly reduced TLE available 24/7 anywhere in the world. The overall precision navigation capability serves as an ideal solution for Intelligence, Surveillance and Reconnaissance (ISR) applications, particularly those involving long distance pointing applications. Other mission requirements are satisfied by the highly accurate velocity and attitude outputs. For repairs, spares, or other life cycle support for this product please contact us.
