In March 2018 Mostcom made a transition from the IT cluster of the Skolkovo Innovation Center to the Space & Telecommunications Cluster. Mostcom became a resident of Skolkovo back in 2011. The company entered IT cluster with the project “Creation of the Equipment for Atmospheric Optical Communication of the New Generation”, within the framework of which a line of models of wireless optical communication systems with capacity of 10, 20, 30, 40 Gbit/s was developed. At the present stage of the company’s activities another project is gaining momentum – “Development and Creation of Unified On-Board Equipment for Space Optical Communication Lines” – has come to the forefront. It was developed in cooperation with JSC Company “Russian Space Systems” – one of the leaders of the world space instrument manufacture. The project is aimed at the development of communication systems between the satellites of the low orbital grouping at distances of up to 5000 km at a speed of 10 Gbit/s with low power consumption and low weight of the terminal.
