LN-120G Stellar-Inertial Navigation System
The LN-120G provides two critical inputs for modern weapons systems: Precision True Heading anywhere anytime and accurate position, navigation, and time during GPS-denied operations.
The LN-120G is a Stellar-Inertial-GPS navigation system. This system integrates stellar tracking and SAASM (Selective Availability Anti-Spoofing Module)-based GPS with a Zero-lock(TM) 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 when GPS is not available.
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.
