en.Wedoany.com Reported - The Russian Satellite Communications Company (ГП КС), in collaboration with the St. Petersburg Special Technology Center LLC (ООО «СТЦ»), conducted a cross-orbit inter-satellite communication experiment. The experiment utilized the small spacecraft CSTP-2.11 in low Earth orbit (at an altitude not exceeding 1,500 km) to complete a communication session via the "Express" series satellites in geostationary orbit (at altitudes between 15,000 and 36,000 km).
Test results showed that the small spacecraft could transmit data back to the ground via large geostationary satellites at a speed of 0.5 Mbps. Alexey Volin, General Director of the Russian Satellite Communications Company, noted that organizing such communication channels using satellites in different orbits eliminates the need for deploying additional ground infrastructure on a global scale. The company stated that inter-satellite data transmission technology will open up new possibilities for small spacecraft operators.

Alexey Volin (General Director of the Russian Satellite Communications Company) stated that organizing communication channels using satellites in different orbits for relay does not require deploying additional ground infrastructure. He believes that the results of this experiment represent an important step in the joint development of services for operators of various spacecraft constellations.
