November 2023—April 2024At the end of November, 2023, despite the unfavourable weather and with some delay, our first satellite antenna was finally installed in Kąkolewo campus. Engineers from ORBIT company, the antenna manufacturer, together with collegues from TESPOL company, the system supplier, implemented this complicated operation smoothly and without any disturbances.It took two days to assemble the radome and the antenna reflector on the ground, while on the third day the components were moved to the top of the tower using a crane and fastened safely. During day 4 the antenna system was calibrated and tested, and finally we were trained by the specialist from ORBIT in system maintenance. The installation and testing of a secondary satellite antenna system took place in Kąkolewo campus at the beginning of April, 2024. Engineers from SpaceComm company, the main system supplier, installed the set of VHF/UHF YAGI antennas as well as C-band, 4.5m diameter parabolic antenna at the top of the tower. All antennas use a single rotator which enables tracking low earth orbit satellites fast and efficiently. The YAGI antennas may be remotely configured to operate in HOR/VERT/RHCP/LHCP modes, independently for transmission and reception of satellite signals. All RF and control cables were installed as well, together with transmitters and receivers (SDR based) and control equipment inside the technical container. The system was calibrated and some initial tests were performed successfully.
