Satellite builders from "RESHETNEV" spoke about one of the new developments. An innovative method of spacecraft orientation has already been successfully tested on the first device of the federal project "Sphere", the demonstration satellite "Skif-D" . It has been in space since autumn 2022, provides high-quality live video communication and other tasks.
A distinctive feature of the orientation method developed at the enterprise is the exclusion of the solar sensor and angular velocity meter from the standard instrument set, which was previously used on low-orbit satellites. On the "SKIF-D" demonstration spacecraft, their functions were performed by a magnetometer and a star sensor. Reshetnev employees also created new algorithms for performing the modes of calming the spacecraft and its orientation to the Sun. This approach made it possible to reduce the cost of manufacturing the "Skif-D" satellite and reduce the amount of testing. Testing in space conditions confirmed the correctness of the technical solutions proposed by the company's specialists.
The new orientation method will be used on spacecraft for the multi-satellite data transmission system "Marathon IoT", the first satellites of which will be launched into orbit by the end of the year. Work is underway to adapt this method for the "Gonets-M1" and "SKIF" devices.
Also, to optimize and speed up production, "RESHETNEV" this year began to create its own section for assembling and testing payload modules for the Express-AMU4, Express-RV, Yamal-501, Luch-5VM and other communication spacecraft. For the same purpose, satellite builders are opening their own production of waveguides.
