Microsatellites in Low Earth Orbits (LEO) have been in use for the past two decades. Low Earth Orbit satellites are used for public communication and also for scientific purposes. Thus, it may be expected that such missions will be further developed in the near future especially in fields where similar experiments by purely Earth-based means are impracticable. Ground stations have to be established in order to communicate with such satellites, and the quality of communication depends on the performance of the satellite ground station, in addition to that of the satellite. Usually these scientific satellites communicate with ground stations at S-band. The performance of the ground station could be disturbed by intermodulation interference because of permanent presence of uplink signal. Intermodulation products caused by GSM signals and uplink satellite signal are potential to disturb, especially in urban areas. Thus, within these papers the interference of intermodulation products caused by uplink signal and any other radiofrequency signal present in the front end of the ground stationīs receiving system is analyzed and then modelled. Based on the modelling concept, the intermodulation interference calculator is introduced as a main application point of these papers.
