LN-270 Pointing Locating Navigating System (PLANS)™ Inertial Navigation System INS-GPS
Northrop Grumman's LN-270 Pointing Locating Navigating System (PLANS) is a complete, integrated land navigator and precision pointing system for ground-based military vehicles. The LN-270 combines a high accuracy, integrated fiber optic gyro (FOG), an inertial navigation system (INS), and a 12-channel P(Y) code GPS.
The LN-270 is the production system based on Northrop Grumman’s GPS Guidance Package (GGP) program. The GGP was a DARPA-sponsored program managed by the Aviation and Missile Command (AMCOM) to develop a technology core of low-cost, modular, fiber optic gyro, and miniature GPS-based guidance systems that can be easily configured to support a broad spectrum of DoD platforms. Successful Army land testing in Phase 1 and Phase II led to the production build of this system.
Applications
The LN-270 brings affordable pinpoint navigation and precision pointing to all classes of ground-based military vehicles.
Advantages
The fully integrated, tightly coupled LN-270 design provides superior positioning, quicker response time, and higher anti-jam performance than simple position navigation (POS NAV), Precision Lightweight GPS Receivers (PLGR), Position, Velocity and Time (PVT) or older embedded INS/GPS systems.
