Maximum likelihood attitude determination on the basis of navigation satellites signals is discussed. Direct maximum likelihood estimation is connected with high DSP computational cost. On the other hand, search of likelihood function maximum can be done under reference phase differences method. Earth’s atmosphere irregularities can lead to rapid fading in received signal power levels. Relations between attitude determination accuracy and a number of satellites is analyzed for different receiving conditions. It has been demonstrated that it is impossible to achieve the same attitude determination accuracy and abnormal error probability range for a low signal to noise ratio as for a high one even thanks to growth in the number of satellites.
