Russian micro-satellite TNS-0 No. 2 has exceeded a period of more than 2 times
The so-called "nanosatellite" domestic production TNS-0 No. 2 working in orbit since August of 2017, when it's launched directly from the ISS for our astronauts. The unit has established not only a record of the work, but also allowed to perform the many necessary experiments for the needs of Russian cosmonautics.
TNS-0 No. 2 was originally built for a simple and inexpensive scheme: this "companion device" (the concept implies an approach to the development, testing and operation of spacecraft as a finished device). If necessary, it is possible to install any payload, to extend the functionality through additional modules, engines, solar panels or the receiving-transmitting devices, as reported by its developers.
The weight of the unit with all service systems is just 4 kg, while it can take on Board up to 6 kg payload. Unlike the TNS-0 No. 2 from the so-called student nanosatellites is that when creating and testing were fulfilled all the requirements for "large" spacecraft. The same applies to installed on Board the spacecraft instruments.
Every day the satellite is at least 10 times sending back data about its status and about the work equipment. Now the number of communication sessions already close to 4000. That gave the work a small Russian spacecraft for its creators from RKS, Institute of applied mathematics im. M. V. Keldysh and RSC "Energia"?
On the TNS-0 No. 2 was successfully tested by the Russian Autonomous navigation system. Its data enabled high precision direct VHF antenna MCC to establish a connection with the device. In the experiment, it was proved that the accuracy of the device provides independent control of the orbit of TNS-0 No. 2 of foreign ground systems like NORAD, which is often used by the creators of the satellites nanoglass.
Was successfully tested as the control channel and data exchange satellite communication system "Globalstar". The modem of this system mounted on Board of TNS-0 No. 2, provided a reliable channel for bilateral data transmission. The use of satellite communications allows you to connect to the satellite from any place on Earth or in space, where there is access to the Internet. To maintain backup communication channel was used installed on Board the satellite VHF radio.
On the basis of the current state of the satellite engineers concluded that its resources could last another almost 2 years. All this time it is planned to carry out additional experiments to determine the extreme deadlines of the various devices of the apparatus in space. These data will allow at minimum cost significantly increase the active lifetime of the spacecraft built on the basis of promising Russian nanoparticulas platform. In the course of further work planned correction software that provides extended time of Autonomous flight up to 30 days. An important step will be the study of the behavior of the TNS-0 No. 2 at the time of entry into the dense layers of the atmosphere. Now experts of the RCC are preparing to launch TNS-0 No. 3 — another apparatus on the basis of a unified nanoparticulas platform that is now used for ground tests conducted on-orbit experiments.
