The results of flight tests of various types of aircraft have shown that an increase in their flight speed, as well as a decrease in flight altitude above the earth's surface, increases the amount of loss and distortion of telemetric information that makes it possible to assess the technical condition of the aircraft.

An analysis of the directions of development of the information and telemetry support system has shown that one of the promising areas for improving technologies for receiving and processing telemetric information is the use of iterative post-session processing methods for pre-detector recording of a group telemetry signal.

In the course of the research, a method was developed for sequentially reconstructing the bit stream of telemetric information based on the singular spectral decomposition of the pre-detector recording of a group telemetric signal, taking into account the procedures for searching for optimal parameters of the singular spectral decomposition, detecting bit boundaries and identifying their information value, and reducing the likelihood of bit error.

The simulation results of the developed method have shown that its application allows for an energy gain of 2-4 dB compared to existing technologies for receiving, registering and processing telemetric information.

Thus, the developed method will make it possible, by reducing the probability of bit error, to increase the reliability of the data obtained on the behavior of various aircraft in flight.
