Overview of Spectrum Characterization / Radio Quietness Profile at CBSS Observatory, Ebirimirin – Agu, Nsukka, Nigeria in June, 2025.
Abstract
This project seeks to characterize Radio Frequency Interference (RFI) around Centre for Basic Space Science and Astronomy (CBSS) premises where a 3.7m Radio Telescope was newly installed in addition to a range of smaller radio astronomy telescopes, radio antennas and RF devices that operate within the premises. The experiment was carried out over a range of frequency bands spanning VHF (35MHz) through C – Band (up to 6.2GHz) to determine achievable science goals, band utilization, system usefulness and performance requirements of any radio astronomy equipment to be operated within the premises. Measurements were taken at specific bands covering VHF (36MHz – 300MHz), UHF (300MHz – 1GHz), L – Band (1GHz – 2GHz), S – Band (2GHz – 4GHz) and C – Band (4GHz – 6.2GHz). The results present the RFI profile of the premises, giving an indication of its radio quietness profile. Thus, the results serve as important guide on astronomy band utilization, equipment performance requirements and achievable science goals within the premises while highlighting attendant effects of urbanization on astronomy studies.
