The issues of processing telemetric information (TMI) of space rocket equipment transmitted over the communication channel in the presence of interfering factors are considered. The aim is to create an algorithm for combining TMIs from geographically distributed receiving stations with a given probability of false alarm in order to improve the quality of processing. Experimental studies were performed on full-scale TMI. The dependences to detect the probability of TMI bit on signal-tonoise ratio for different number of receiving stations are constructed. It is shown that the use of information from 2 of 5 receiving stations allows to increase the average probability of detecting TMI bit Pо by 3-5 % (from 0,959 up to 0,995 ) in comparison with the combining rule «1 of 5 » with different signalto-noise ratio and the probability of false alarm 3 Pлт = 10-3.
Key words: telemetry information, receiving stations, interfering factors, frame allocation, distortion of words, integration of telemetric information, processing quality improvement.
