Littons LN-1006: A Small Embedded GPS Inertial Navigation Unit

William M. Johnnie

Abstract:	To meet the demand, for an embedded GPS/INS navigation system, Litton put in place an internally-funded phased development program. This system is based on the proven Rockwell Collins GPS atchitechue and the Litton Advanced Technology LN-100 product line currently selected for the Longbow Apache INU, the Comanche Navigation Quality Inertial Sensor, the F-22 Inertial Refer- ence System and the Multi-Service Launch System navi- gator. The combination of these two technologies will result in a navigation system that is small at 7x7~11 inches, light at 22 pounds, and low power at 32 watts. This paper describes the equipment architecture and performance goals from both a hardware and software standpoint of the preproduction systems as well as some of the enhancements planned for in the production system. Additionally, some of the problems that occur with respect to the validation of the performance of these systems will be discussed.
