In the second part of the series of articles, the issues of the systemic organization of mathematical models for solving the problem of controlling the flows of target information in the Earth remote sensing space system are considered. A description of the interrelated mathematical models of the orbital constellation as components of the information system, the main task of which is to survey ground objects and the formation of the initial volume of information for its further processing, is presented. To calculate the time of servicing the request by the space segment, the following methods of formation are proposed: a model of the evolution of the Earth remote sensing spacecraft orbit; model for forecasting possible spacecraft correction intervals to maintain nominal orbital parameters; model for forecasting possible time intervals for on / off cycles of observation equipment; model for forecasting possible time intervals for dumping the received information to the information reception points. When calculating the cost of servicing a single request from the orbital complex, both the cost of servicing one spacecraft per unit of time and the cost of processing a single request from the ground complex were taken into account. In conclusion, a generalized form of representation of the target information flow model of the Earth remote sensing space system is proposed as an interconnected sequence of functions for changing the amount of information when an appropriate processing process (traffic change functions) is applied to it. General approaches to solving the optimization problem are considered.

The article is devoted to the formalization of the problem of distribution of target information flows during the operation of the ERS space system. It is proposed to consider the system as a complex, geographically-distributed information system, the main task of which is to implement a full service cycle, starting with the formation of an application and ending with the provision of a finished thematic product. The decomposition of the ERS space system as a complex information organizational and technical system was carried out, the system and consumer characteristics of its elements were determined. The possibility is substantiated to carry out an objective curtailment of system performance indicators and go to two particular ones that characterize the effectiveness of the target functioning of the system as a whole: the promptness (time) of fulfilling consumer requests for a finished thematic product and the cost of the finished thematic product. A general methodological approach to solving the technical problem is proposed. The result is a formal presentation of the task of distributing the streams of target information during the operation of the ERS space system as a sequence of the following operations: formation of an application; determination of the list of requests to the system required to complete the application; determining the processes and the sequence of their execution that will process the corresponding requests; optimization of the time distribution of processes among the elements of the system, taking into account the selected performance indicators and existing limitations.

The paper presents basic results of exploratory design studies into a space system for real-time monitoring of the Earth surface based on small spacecraft* for Earth remote sensing, which provides acquisition in real time of highly detailed Earth surface images with resolution of 0.7–1.0 m, a swath of 20 km and 15m in-plane georeferencing accuracy from a ~300 km orbit with a mass of spacecraft ~200 kgf repeating with high frequency (at least every 1.0–1.5h). The said parameters are in line with the current state of the art and are quite feasible for our country’s industry. _________________________________________ * — for the purposes of this paper ‘small spacecraft’ is a 150-220 kg spacecraft.

In the paper is considered a possibility of remote sensing application on the basis of pilotless aviation systems for management and monitoring needs and the substantiation of costeffectiveness of these measures. The investigation is based on the own long-term skill of practical operation of Supercam pilotless air-survey complexes and also on the analysis of mar-ket and cases with the successful use of results of the Earth pilotless remote sensing for town needs. A current market of the Earth pilotless remote sensing in Russia, suppliers and consumers of this service are analyzed. Besides, in this paper are considered kinds of payload specified for a pilotless vehicle (PV) for the Earth remote sensing, potentialities of modern systems. There is carried a computation of costs for the formation of a data support department of remote sensing with PV and assurance of its functioning in the course of a year for needs of a municipal district. An example of the successful use of pilotless aerial photography for the needs of the Zvenigorod municipal formation. The cost-effectiveness of new technology introduction is proved. The data advantages of the Earth remote sensing with high resolution for effective management so-lution-making in municipal formations are shown.

The article deals with the issues related to the problem of ballistic design of the space system of remote sensing of the Earth on stable near-circular solar-synchronous orbits with long-term existence of spacecraft. We propose a rational method of maintaining a solar-synchronous orbit in given light conditions with prolonged active lifetime of space systems. In solving this problem, the total time of normal operation of the system for a given period of operation, during which the most favorable conditions for the use of spacecraft are provided on the main parts of orbits, is taken as a target function.
