A new unified satellite platform has been developed at JSC "RESHETNEV", which will be useful for implementing the project to launch the "Marathon IoT" satellite constellation.
The platform consists of cellular panels with a set of service system equipment. These include an onboard control complex, orientation and stabilization systems, correction, thermal control and power supply.
The spacecraft has one solar panel wing. It is equipped with silicon-based photoconverters. Industrial batteries and a passive thermal control system based on screen-vacuum thermal insulation and optical solar reflectors are also used. Such technical solutions will help assemble this and other series of satellites faster and cheaper.
It is assumed that on the basis of this platform it will be possible to create other microclass satellites weighing up to 100 kg for various purposes.
Prior to this, "RESHETNEV" had already created a new unified domestic platform for large spacecraft weighing up to a ton. In one launch, the platform will be able to put up to four satellites into low circular orbits.
