Aerospace Instrument-Making Annotation << Back SEPARATION OF SIGNALS OF TELEMETRY AND TELEVISION IMAGES OF SPACECRAFTS Yu.S. Sagdullaev, A.I. Smirnov, V.Yu. Sagdullaev During the dynamic modes of manned spacecraft «Soyuz» cargo spacecraft «Progress » and the Russian segment of the International Space Station (ISS) information on the traffic management system of transport and cargo spacecraft (SC) is transmitted as on a separate telemetry (TM), as well as TV channels communication. Onboard information TM spacecraft transmitted by television (TV) channel in co-operation with the TV image of the spacecraft formed by the outer board TV camera. In this case the TM information about dynamic parameters of spacecraft motion is displayed as a symbol on a background of TV satellites images. Change event is characterized by a change in the relevant letter messages. This article discusses issues related to the selection, recognition and recovery of lost messages partly symbolic TM information. Shows the possible options for changing the character TM contrast information on the background of TV satellites images. We consider some approaches to the selection and recognition of TM data signals, signal processing, and signal separation joint telemetry and television images. Block diagrams of devices designed selection and fixation of current changes in the character of TM data signals, the formation of TV satellites images without symbolic information TM, TM data selection in the TV images of the spacecraft with restoring messages while partially lost alphabetic characters of information. It provides a general block diagram of the device separation telemetry signals and TV satellites images. Implementation of operations commit the changes and restore the symbolic message TM information will lead to increased effi ciency and quality performance of dynamic spacecraft control regimes, including the process of rapprochement. In general, considered algorithms and signal processing circuit TV images provide separation between themselves on the receiving side of the TM and TV information in their implementation will contribute to the improvement of information support specialists MCC, control of the spacecraft flying in their approach mode. Key words: spacecraft, convergence, television images, telemetry information processing and signal separation, selection and recognition of telemetry signals.
