Luch is the brainchild of the Information Satellite Systems Company named after Academician M.F. Reshetnev “(ISS). A number of innovative technical solutions were used to create the satellite. In particular, the device was equipped with a multi-band repeater and three large-size umbrella-shaped antennas with a diameter of 1.5 m, 3 m and 4.5 m. For their compact folding under the fairing of the launch vehicle, the reflector was made of a special metal mesh cloth.

After launching into orbit, Luch provided two-way communication between cosmonauts at the Mir station and specialists from the Mission Control Center, receiving information from low-flying spacecraft, etc.

In 1995, the Luch-2 satellite was launched. At present, the orbital constellation of the system consists of three geostationary spacecraft: these are the Luch-5A, Luch-5B and Luch-5V satellites, which were launched into orbit in 2011, 2012 and 2014, respectively. They provide retransmission of data from the International Space Station (ISS), transmission of GLONASS and COSPAS-SARSAT signals, retransmission of information from launch vehicles, upper stages, Earth remote sensing devices, etc.

In the future, it is planned to upgrade the platform, providing for the launch of two Luch-5VM vehicles with an additional load for special consumers.
