Abstract
The bit error ratio (BER) and power are very hard to calculate in space optical communications, having lots of effect factors, so need compromise to consider the complex factors. Analysis the influence to the BER such as beam drift, beam divergence angle, communication distance, link loss, detector sensitivity etc. Propose the view of ellipse gauss beam can inhibit beam drift by the random shock and relative motion of the optical platform and reduce the BER, and further propose the method of calculate the transmit power using the BER. Experiments showed that it is security to use the calculation methods of BER and power.
