DSC_0646Today the leading universities actively encourage students and young scientists to create nanosatellites – tiny CubeSat spacecrafts (weighing about 1 kg with dimensions 10×10×10 cm). Apart from meeting purely educational challenges, such spacecrafts are used for the implementation of a number of scientific, technological and social projects for different purposes. Some of the world’s leading companies have already been working on the issue of nanosatellite-based access to the Internet for users who are in hard-to-reach places of our planet.
The KPI design of the spacecraft PolyITAN-1 is based on using its own original results of scientific and technological achievements in different fields of science. In particular, the scientists of Heat-and-Power Engineering Faculty have used their honeycomb panel carbon composite structures, which the scientists from the Faculty of Electronics integrated with their photo-silicon converters with efficiency up to 20%. The experimental solar battery provides power supply for all electronic systems of the nanosatellite. Radio communication channels and radio control links were created by the experts of the Radio Engineering Department. At the heart of their development there are the original antenna and digital programmable circuit technology solutions. Together with the scientists from the Radio Engineering Department a ground station was created with the participation of the specialists of the Educational and Research Institute of Telecommunication Systems.

The purpose of launching the satellite is scientific: studying the solar sensors for small spacecrafts, testing the power engineering of the solar power supply, designed at the University, adapting to the conditions of space and improving the digital radio transmission channels, studying the influence of space on the functioning of electronic subsystems, studying the GPS operation of the original design.
For tracking the flight of the spacecraft and conducting the planned research there was established a center with the necessary test equipment at the University. And the young researchers will also use the results obtained during the flight while designing the new constructions of small satellites, the creation of which is specified in the agreements NTUU “KPI” has concluded with other universities.

Nanosatellite was launched into orbit in Holland on June 19, 2014. The Associate Professor, Candidate of Technical Sciences Antypenko Ruslan Volodymyrovych (now Head of RSP department) was directly participating in the launch.
In the framework of the international launch project there were 33 spacecrafts, 21 of which were nanosatellites, created in different countries. The launch was performed by Ukrainian carrier rocket “Dnepr” of Ukrainian origin, as its basis was the conversion ballistic missile RS-20, produced at the Dnepropetrovsk plant “Pivdenmash”.DSC_0648

Immediately after the launch of the satellite radio beacon of PolyITAN-1 EM0UKRI was heard not only in the university center. It was also detected by radio amateurs in Kyiv, Slavutych, Kharkiv, and in other countries of the world. Today nanosatellite successfully operates in Earth orbit at about 700 km from the Earth, having the rotation period of 97.8 minutes. In five out of 16 daily revolutions around the Earth there is a short time (from 2 to 9 minutes) possibility of the communication between device and ground station installed at the KPI. Within these minutes developers are getting the telemetric information on the functioning of individual nanosatellite subsystems, which is required for future operation.

Today the scholars of the Radio Engineering Department are already working on radio systems for the next international project QB50. Within the framework of the project a cluster launch of 50 nanosatellites of the leading universities is to be made for the purpose of study in the upper layers of Earth’s atmosphere.
The lecturer of the Department of the Radioreception and Signal Processing Pershyn Mykola Oleksiyovych made the international frequency assignment authority (frequency allocation) at the International Amateur Radio Union for the nanosatellite Polyitan-1 operation. (03/22/2014).
And also he made the international frequency assignment authority (frequency allocation) at the International Amateur Radio Union for the nanosatellite KPI-SAU-1 to apply for QB50. (06/10/2015).
