Procedure of accomodation of earth remote sansing satellite external devices with regard for the satellite target operation

Abstract


The paper dials with the problem of accommodation of external devices of the Earth remote sensing satellite (ERSS). It is shown that it has a significant influence on the ERSS conceptual design and target characteristics of a space system as well as partial efficiency indices of the support systems.  Models and algorithms have been developed which allow estimating partial efficiency indices used for choosing the sites and angles of installing the devices. Among these devices are solar cell battery panels, radiators, star trackers, laser intersatellite link devices, satellite navigation system antennas, etc.  Partial efficiency indices used for the appropriate accommodation of the external devices are assessed with the help of the software based on the simulation of the satellite orbital motion, conditions of its operation, target turns, and interaction with other objects of the orbital constellation. Some results of testing the proposed procedure are given. As an example, it is shown that for ERSS with sun synchronous orbits the average cosine of the angle between the Sun line and normal to the plane of the solar cell battery depends upon the longitude of ascending node to a great extent.
