- The Earth Station in Motion (ESIM) system is one of the most modern satellite systems, providing high-speed and high-capacity communication with mobility. To operate the ESIM in the Ka-band, a compatibility study with incumbent services should be considered for the protection of existing services. This paper provides a methodology to assess the interference from ESIM to an FS in the same Ka-band, taking into account the antenna pointing errors occurred inevitably by the tracking antenna system of the ESIM. Based on a point-to-point interference scenario, the simulation results show the interference distributions according to the elevation angles of the ESIM and the distances between the ESIM and FS. In addition, a separation distance of up to 38 km should be guaranteed for protecting a victim FS receiver taking the results of simulation into consideration.
