³Ô¹Ï¹ÙÍø has been engaged in the creation of unique equipment for domestic cosmonautics for a long time. A recent development, commissioned by RESHETNEV JSC, is an experimental dose control complex (EDCC). The device is successfully completing flight tests on the Skif-D spacecraft.
Vitaly Prokopyev, NSU Aerospace Research Department Head, explained,
With the help of this device, a unique experiment is being carried out to study the radiation situation in a medium circular orbit - 8070 km with a polar inclination of 90 °. This is a little-studied and practically unexplored orbit to date.
Scientists note that examining this orbit also opens up great prospects for the development of broadband Internet services in Russia, which cannot be implemented in traditional geostationary and low Earth orbits. This is the best height to place equipment for providing stable Internet communications to remote and sparsely populated regions of Russia, including the regions of the Far North, the Arctic, the Northern Sea Route, and cross-polar air routes. A wide viewing angle will allow this task to be implemented by a relatively small group of devices.
To work out a number of technical solutions related to solving this problem, the Skif-D apparatus was launched last autumn. Along with other equipment, an EDCC was installed to study the level of radiation that affects the satellite and its subsystems. This is done using a matrix of nine sensitive elements, IADRM (integral accumulated dose registration module). Each of them is isolated from the others and has its own unique radiation protection system. After long-term observation of the individual module readings dynamics, it is possible to obtain qualitative data on the composition of ionizing radiation from outer space at a given orbit. An analysis of this information will make it possible to determine the limiting values of radiation at a given altitude and draw conclusions about the degree of its impact on the spacecraft and the possibilities for protecting the satellite subsystems.
Vitaly Prokopyev summarized,
Our device has been working properly on board the Skif-D for eight months, so we can say with confidence that we have successfully passed the flight test stage. We plan to continue conducting orbital experiments. An experimental version of the device under the CubeSat form factor for installation on small spacecraft is already ready.
