Abstract

Testing of an inertial navigation system (INS) aimed to verify its compliance with the requirements for the accuracy of its heading channel by comparing it with a reference INS with known accuracy parameters is discussed. It is shown that the main conditions for successful testing are the following two factors: the proportion (ratio) of the errors of the heading channel being tested and those of the reference channel, and the estimation accuracy of the reference channel errors. Formulas are obtained for the case of a zero systematic error of the reference heading channel, which provide reliable estimation of the comparison results.
