Autonomous Navigation Technology (ANT) System.

Abstract

A laboratory evaluation of an Interferometric Landmark Tracker (ILT) for an autonomous spacecraft navigation system was conducted. The system processes ILT, inertial reference unit, and star sensor data in a Kalman filter to provide in-space navigation. Sighting accuracy measurements were made over a 120 degree field-of-view on a four-antenna interferometer in an anechoic chamber. Error data from the interferometer measurements were used as inputs to Monte Carlo simulations of the spacecraft and orbital dynamics to determine navigation accuracy for several orbital conditions. Navigation errors and interferometer sighting errors were analyzed in terms of order statistics and cumulative distributions.
