Results of orientation definition precision research of a satellite due to TRIAD algorithm are described in this article.Investigation was conducted at referenced maximal admissible meanings of measurement unit errors and also elucidated vectors coordinate displacement in dependence of microsatellite orientation angles initial values at which the greatest errors of determining orientation angles could have place.Findings of performed researches will give an opportunity of orientation angles definition accuracy increasing of a spacecraft.Investigation of orientation accuracy is considered to be a quite cumbersome and time consuming challenge so as a consequence for resolving this problem interactive computer model of microsatellite orientation system was developed and created including a special tab for orientation angles accuracy studying of microsatellite by means of TRIAD algorithm.Interactive computer model allows in dialog mode to consider measurement unit instrumental errors effect on orientation system accuracy of microsatellite. Satellite dynamic features also are built into this model which makes possible to analyze precision of satellite orientation system in whole.It is easy to change algorithm of orientation determining, for instance, to QUEST algorithm. In its turn it helps estimate one more important task – to compare different algorithm efficiency of satellite orientation.
