This article considers multi-satellite Earth remote sensing space systems that provide global coverage. The aim of the study is to provide a comprehensive model for assessing the effectiveness of multi-satellite Earth remote sensing space systems. Firstly, the structure of the Planet multi-satellite system was analysed by considering the design issues of modern multi-satellite Earth remote sensing space systems. Secondly, models for estimating coverage, models for assessing operability and periodicity were considered and a number of constraints for performing simulations were proposed. Using such constraints in the process of simulation modelling makes it possible to adapt the system and simulate different scenarios of operating the on-board equipment, which in turn makes it possible to obtain results close to the real ones. Finally, a comprehensive model for assessing the performance of multi-satellite Earth remote sensing space systems has been proposed. As a result, modelling and performance assessment of three space systems providing a global view of the Earth’s surface with a revisit time for each point at least once per day was carried out.
Keywords: small spacecraft, remote sensing space system, multi-satellite system
