Negotiations are underway to launch the first round of satellites from the International Space Station (ISS) in 2021 as part of an interdisciplinary project called “Small Spacecraft Group”, Tomsk University of Technology (TPU) in Russia Engineers of at least five 3D printed CubeSat satellites into orbit. The main purpose of the experiment is to test the possibility of automatic interaction with space objects, especially in navigation and communication tasks. The TPU’s Student Mission Control Center (MCC) will use a satellite control system to track and supervise equipment on Earth and ensure that the micro-spacecraft can respond to all their requirements.
Andrey Kolomeitsev, Assistant of the Department of Electrical Engineering at TPU, said: “Satellites will have to be built according to instructions, move in orbit, maintain formations, interact with the Earth and each other, and change and coordinate their positions based on the received data. At MCC, we It will ensure that the satellite performs its functions, track trajectories, receive telemetry information, monitor engine conditions, and send commands to the vehicle when necessary to ensure realignment.” MCC was created by students and lecturers and is the TPU Space Engineering Virtual Design Center (VDC) It also trains students on the flight control of small spacecraft in orbit, which arouses people’s interest in the rocket and space industry and helps them realize innovative technical solutions.
The mission control center (MCC) students monitor the launch of the Tomsk-TPU-120 satellite. In order to control the CubeSat group, the team will need an antenna that can provide reception services anytime and anywhere; automation system; capable of receiving and processing information from all spacecraft at the same time Equipment; and an experienced team. Alexey Yakovlev, Dean of TPU’s School of Advanced Manufacturing Technology, said that TPU students and graduate students already have extensive experience in handling satellite transmission and operation. In 2017, the five-kilogram nanosatellite 3D Tomsk-TPU-120, printed by TPU students and faculty using dynamic models, was manually deployed into orbit during the Russian spacewalk on the International Space Station. At that time, astronauts Fyodor Yurchikhin and Sergei Ryazansky just opened the exit of a docking module, turned on its power system, and then released it into space.
TPU has the technical capabilities and expertise to receive and process information and manage satellite constellations. At MCC, students were trained to receive signals from satellites flying over the city of Tomsk, Russia. Whether it’s a Chinese satellite that uses Morse code to send call signs, or the institute’s own 3D printed Tomsk-TPU-120 satellite telemetry transmission technology, next year, when multiple satellites begin to operate in space, these routine tasks will be dispatched. Useful. Moreover, they are ready to deal with CubeSat failures and know how to solve any spacecraft problems caused by space dust, collisions, space weather and internal failures.
The students and staff of TPU participated in the project at the invitation of Alexander Chernyavsky, the main developer and contractor of the Russian space shuttle program, and the consultant to the general manager of the rocket and space company Energia (RSC Energia). According to China 3D Printing Network, 15 Russian organizations and universities will participate in space experiments, including the development of CubeSats and launch platform equipment located on the International Space Station.
With the help of TPU, other well-known participants in the project include Skolkovo Institute of Science and Technology, RSC Energia and Samara developers. Their task is to create special software to control the CubeSats group, which will improve the ability to receive and send. “In the future, space traffic will become more active, and multi-agent interaction will be very important, so today the control technology must be tested. That’s why this is a very important experiment.” Kolomeitsev said.
Comment on China 3D Printing Network: The use of 3D printing technology to design CubeSat bodies for cheaper and faster tasks is nothing new, because many agencies, startups and universities have been doing this for several years. Microsatellites are very suitable for encouraging students to send projects to orbit, and even space agencies encourage students to develop their own CubeSats, such as the CubeSat launch program of the National Aeronautics and Space Administration (NASA), which is suitable for high schools, universities and non-profit organizations, or European aerospace The CubeSat Educational Program of the Agency (ESA) is called “Flying Satellites!”
Which provides college students with the opportunity to develop their own space missions. For TPU Russian engineers, manufacturing small multi-purpose satellites has always been one of their priorities, especially because having the CubeSat satellite group in orbit will help them deal with agriculture, forest fires, climate change and the natural environment. Many urgent issues. Resources and help test new technologies in space materials science. As space exploration advances, we will continue to discover projects that combine technology and innovation to allow more satellites to be deployed into orbit than ever before.
