Increasing efficiency of getting results of satellite remote sensing for smart cities

Satellite Earth remote sensing data are widely used in Smart Cities in various areas, such as energy industry, transportation area, or disaster monitoring. Real time remote sensing data from some region could help to parry various extraordinary (emergency) situations (forest fires, floods, emergency situations on roads, etc.). It could be used in control centers to support decision making able to promptly inform citizens about current situation. In order to have the actual data, it is necessary to perform Earth observations as soon as possible after an emergency situation arises. But before the data from a satellite can be provided for its processing, a number of tasks must be solved. One of such tasks is changing a schedule of tracking, telemetry and command (TT&C) ground stations to carry out a communication session with remote sensing satellite for sending on it program of target equipment work (to observe the region and downlink sensing data to receiving ground stations). In this paper, the authors propose approaches to increase the efficiency of changing a schedule of TT&C ground station in order to increase the efficiency of getting satellite remote sensing data. Such issues as organization information exchanges between subscribers, prompt notification of planning department specialist about changing the current situation, increase efficiency of including in schedule additional communication sessions, the informative representation of data about current situation are discussed. The proposed approaches can increase the efficiency and reasonableness of the decision making in control centers to parry various extraordinary (emergency) situations. In turn, it can make cities more sustainable and safe, in other words smart.
