- Abstract
Same event is happened each time during satellite launch – mechanical separation of the satellite from the launch-vehicle. Exactly from this moment satellite begins its operations as a single physical body. On the other hand, there is another operating object on orbit close by the satellite, namely, last stage of the launch-vehicle. At the same time, telemetry data acquisition system and reserve of onboard telemetry system are presented to provide an operation of launcher last stage. Finally, after completion of main launcher task, telemetry information content is steeply reduced. Moreover, most of scientific and technological experiments do not require long time of orbital operation of the equipment; there are no any strong requirements to housekeeping subsystems, so it could be realized using resource remnants of last launcher stage. Considering fact that mass of the satellite or cluster satellite launch is always less than potentialities of launcher for power generation, then last stage has a reserve for installation of the experiments. This paper contains an assessment of making scientific and technological experiments on-board the last stage of launch-vehicle, analysis of common technical problems emerging during realization of such kind of problems and methods of their elimination. For conversion Dnepr launch-vehicle designed by Yuzhnoye SDO, the limiting parameters of experimental equipment are calculated; example of realization
