The evolution of rocket and spacecraft is characterized by an increase in flight speeds up to hypersonic and the dynamics of flight trajectories. In these conditions, to transmit information from on board flying machinery, it is necessary to develop digital telemetry systems that are optimal in terms of the required throughput, accuracy of reception and digital processing of information in conditions of dynamic trajectory, short communication session time, a wide range of flight altitudes, and the multi-path nature of radio wave propagation. This article provides an overview of the author's works on the created simulation model of a digital radio telemetry system (RTS), algorithms for selecting the parameters of the RTS radio channel, algorithms for the optimal location of RTS receiving points, methods for combining signals received by several receiving points, providing a throughput of up to 8 Mbit/s, a bit error probability of 10–5– 10–4, a radio channel reliability equal to one throughout the entire flight path of an flying machinery based on the provisions of the complex signals theory and the transmitting discrete messages theory.

The features of several developed telemetry systems, which are currently widely used in flight testing practice, have been presented.
