INERTIAL NAVIGATION SYSTEM PROVIDES POSITIONING TO GPS-DEPRIVED AREAS

摘要

For military units on the network edge, GPS satellite guidance isn't always readily available. With Honeywell's Tactical Advanced Land Inertial Navigator (TALIN), however, vehicles and artillery can navigate such areas more precisely to increase troop safety and maximize mission success. Honeywell recently signed a licensing agreement with Tata Power's Strategic Engineering Division (SED) to produce TALIN in India. Incorporating ring laser gyroscopes (RLGs) and quartz accelerometers (QAs), TALIN is a high-accuracy, shock-stabilized position and pointing inertial navigation system for military and commercial platforms. The digital RLG, an inertial sensor, measures the difference of frequencies between counter-propagating laser beams to provide the rotation angle or rotation rate about the RLG's sensitive axis. That data then helps determine the orientation of a system in inertial space.
