We consider the problem to increase the accuracy of determining spacecraft orientation using information obtained from two jointly processed star trackers. One of the trackers is the main one. Its information is specified by the second tracker. A mathematical model of the main star tracker error is constructed and an error correction algorithm of using second star tracker is proposed. We present some results of numerical simulation of the algorithms
