In this article the development task of algorithmic and simulator complex software allowing to form the plan of information transfer from the space vehicles tandem onto the receiving information points is considered.
Analysis is carried out for two variants of the plan transmission informations obtained as a result of fulfillment supporting observation plan: in the first case the information from tandem goes to the receiving information points; in the second case the information from tandem goes directly to the receiving information points as well as through relay satellite onto the receiving information points.
The simulated results can help to choose a data transferring plan when the volume of transmitted information will be maximum (maximized).
The present study provides a starting-point for the further research in the international aerospace industry.
Necessity for the practical solution to such kind of tasks arises because of the radar interferometric survey of earth surface now is in use on the basis of space vehicles tandem, which gives a chance to create the digital models of relief and earth locations with high precision, allows to carry out all-weather monitoring of natural and man-made disasters consequences, makes possible to solve the problems of ensuring defense and safety.
