Abstract:

The Completely Integrated Reference Instrumentation System CIRIS is operated by the Central Inertial Guidance Test Facility CIGTF, at Holloman AFB, New Mexico. CIRIS functions as a reference navigation system used for evaluating the accuracy of other types of navigations systems. As a reference standard, the root-mean-square errors in CIRIS estimates of aircraft trajectory variables must be maintained an order of magnitude smaller that the corresponding errors of the navigation system under test. The primary hardware components of CIRIS are a reference inertial navigation system INS, a baro- altimeter, an array of ground-based transponders, a transponder interrogator, and data recording equipment. The transponder equipment provides transponder-to- aircraft range and range-rate measurements during test flights. The primary software component of CIRIS is a Kalman filter program which processes the recorded measurements and estimates the true position and velocity of the aircraft throughout the test flight. The estimation accuracy of CIRIS must be increased so that CIRIS can serve as a benchmark for measuring the accuracy of Global Positioning System GPS aided inertial navigation systems. This thesis documents the continuation of research to develop completely new Kalman filter software for CIRIS.
