Information support for upper stage missions to launch deep space spacecraft involving the use of a satellite data transmission circuit

The paper discusses implementation of information and telemetry support for missions of upper stages when they launch spacecraft into deep space. A key feature of an upper stage mission consists in relaying low-rate telemetry data via multifunctional space repeater system Luch using low data rate user relay equipment. The paper proposes an approach to processing and presenting telemetry data, which make it possible to determine g-loads acting on the upper stage and its attitude angles from measurement of the satellite navigation equipment during powered flight.
