Error Analysis and Performance Data from an Automated Azimuth Measuring System,

Abstract

The determination of precise time-dependent azimuths is an important requirements ofr evaluation and maintenance of inertial navigation instruments. Improved technology now demands a test and evaluation accuracy of less than one arc second, which means that geophysical and environmental effects on the time-stability of azimuth references are now quite significant. Similarly, azimuthal motions of the test equipment, which are inherent in the tests themselves, must also be evaluated. This paper discusses an automated inertial azimuth measuring system which was used to track the azimuthal motion of test references at Holloman AFB, NM. A detailed error analysis fo the system and methods to improve performance and accuracy are presented. Discussion includes selected alternatives for improving state-of-the-art azimuth measurement.
