Development of the Extended Kalman Filter for the Advanced Completely Integrated Reference Instrumentation System (CIRIS)
Abstract
The Completely Integrated Reference Instrumentation System (CIRIS) was developed by the Central Inertial Guidance Test Facility (CIGTF) at Holloman AFB, NM. The CIRIS system is an inertial navigation system (INS) aided with line-of-sight range and range-rate measurements from surveyed ground transponders. The information from the measurement and INS data is combined using an extended Kalman filter to produce an accurate estimate of the INS position and velocity errors. The accurate CIRIS aircraft position and velocity data is used as a baseline reference to determine the performance capabilities of proposed aircraft navigation systems. The new aircraft navigation systems projected in the next five years will attain accuracies approaching the level of the current CIRIS system. In order to test these systems, the accuracy of CIRIS will be increased through the addition of aiding measurements from the Global Positioning System (GPS).
