In modern conditions, the requirements for ensuring the completeness and quality of registration of telemetry information during testing and operation of aircraft have become much stricter, since it is based on the results of the analysis of this information that it is possible to assess the current technical condition of both the aircraft itself and its onboard systems. Analysis of the development of approaches and methods for recording and processing telemetric information has shown that a promising direction is to use the functions of pre-detection recording of a group telemetric signal and subsequent post-session processing of the registered data volume using complex methods and algorithms.

One of these approaches is the application of a fairly new and increasingly widespread approach, which consists in the use of singular-spectrum analysis. The article describes in detail the developed algorithm for the recovery of telemetric information, expressed in the consideration of individual information-significant telemetric parameters, based on the application of the method of singular spectral analysis of the pre-detector signal recording, as well as the results of modeling the use of this algorithm for recovery.

The results of simulation of the developed algorithm showed that its use, depending on the conditions for receiving a group telemetric signal, in particular the signal-to-noise ratio at the input of the receiving and recording equipment, allows increasing the reliability of the representation of information-significant for assessing the technical condition of the telemetric parameters by 8…85 percent compared to the existing technology for recording telemetric information.

Thus, the proposed algorithm for restoring telemetric information, based on the use of the method of singular-spectral analysis of the pre-detector signal recording, allows providing a more reliable assessment of the technical condition of the aircraft under difficult conditions of signal reception, when the telemetric information is registered in real time by ground equipment. The field of application of the developed algorithm is complexes of post-session processing of telemetric information.
