Brian Fly, Steven Kim, Joe Franiak, and Darryl Larson, Northrop Grumman
Location: Ballroom E
Date/Time: Wednesday, Jun. 4, 5:05 p.m.

Based on the Fiber Optic Gyro (FOG) Family of Products, the LN-270MSR is the smallest, lightest, lowest power and most reliable Pointing, Locating, Navigation and Stabilization system in its class, with unsurpassed geo-location and velocity accuracy. It is a highly adaptable non-dithered solution with the lowest Angle Random Walk (ARW) of any land navigation system. The non-dithered, low noise FOG technology eliminates self-induced acceleration and velocity noise in the inertial sensor, creating exceptional pointing performance and increasing sensor accuracy over current dithered navigation devices.
Now, Northrop Grumman is proud to introduce the LN-270MSR, which is an improved inertial land navigation system that incorporates M-Code GPS, the new SuperFOGTM technology, our newly developed continuous rotation software, and a resilient time A-PNT feature.
These features and capabilities provide the host platform with:
1) M-Code GPS which provides enhanced jamming immunity and a tightly coupled inertial/ GPS solution for even better immunity
2) The newly developed SuperFOGTM technology providing pointing accuracy to <0.4 mils rms in dynamic environments and <0.001 mils rms in “staring” or long-term stationary emplacements.
3) Maintains attitude accuracies while operating on continuously rotating platforms such as radars or other scanning implementations.
4) Resilient time of <500 nanoseconds up to 2 hours after loss of GPS.
This paper will describe the LN-270MSR in detail and provide real world testing results.
