ISS-Reshetnev Company currently works on the multifunctional space-based data-relay system Loutch operating in the geostationary orbit, and builds satellites intended for this system.
Data-relay satellites of the Loutch series enable data retransmission from the Russian segment of the International Space Station, manned and unmanned low-orbiting satellites to the ground control centers and ground receiving stations. Apart from that, these satellites also enable data exchange between ground infrastructure units and users. Additionally, data-relay satellites of the Loutch series are used to retransmit hydrometeorological data from the Russian Hydrometeorology and Environmental Monitoring Agency, signals of the International Satellite-Aided Search and Rescue System COSPAS-SARSAT as well as those of the Differential Correction and Monitoring System for GLONASS users.
One of the main characteristics of the Loutch system is that it provides full global coverage: data-relay satellites that are part of the system receive data from low-orbiting space technology objects (such as launch vehicles and their upper stages) on powered and unpowered sections of the trajectory when these objects are not visible from the territory of the Russian Federation and then further relay information to ground receiving stations located in Russia in a real-time mode.
The multifunctional space-based data-relaying system Loutch is being built up as part of Russia’s Federal Space Program.
