This article discusses the temporary accumulation algorithm applied to problems of monitoring and quality control off the navigation satellites GLONASS signals. The proposed algorithm allows to work by increasing the signal/noise ratio in the counting exercise recovery waveform elements or code sequence off the navigation satellites GLONASS signals. Method temporary storage based on a combination of the same signal elements (elements of the same shape) transmitted at different instants and based on the fact that the time waveform at different time intervals repeats. The corresponding energy gain (increase in signal / noise ratio) at the same time is proportional to the accumulation. The proposed algorithm in the article has been approved temporary storage when receiving navigation satellites GLONASS signals from large aperture reflector antenna with a gain in the frequency range 35 dB L1 and omnidirectional antenna with a gain of 3 dB. The results of shape recovery and elements of the code sequence of navigation satellites GLONASS signals.
