Abstract
As more and more spacecraft launched into the space, the probability of radiofrequency (RF) interference raises and the burden of RF spectrum management increases as well. The monitoring of global RF beam information and identifying of spot beam emitters location can effectively obtain space data resources, which will do great help for mitigating global RF interference and optimising space spectrum resources. This study proposes a novel location awareness method for spot beam emitters based on the nanosatellite platform. The proposed method identifies the position of spot beam emitters on a global scale by flying a low earth orbit CubeSat constellation through the coverage of the spot beams. The properties such as geometry, the target motion equation, the measurement process, and the Particle Filter equations are all addressed with respect to the location methods. The authors illustrate a realistic scenario simulated within the Systems Tool Kit, in which CubeSats receive signals from the spot beam emitters. The scenario shows that their location awareness method proposed in this study is available and efficient.
