| Abstract(in English) | The earth observation missions have been improved its sensor performance, it results in a huge amount of data to be stored in remote sensing satellite and transmitted to a ground station. Although, satellite to ground transmitter had been usually used X band, several mitigation techniques for rain attenuation have been studied in recent years to migrate to Ka band for broadband transmission. Furthermore, Q band is expected to achieve higher data rate because of its broader bandwidth. However, Q band is shared with terrestrial networks, remote sensing satellite has to take into account potential constrains to them. Therefore, this paper addresses remote sensing satellite network and proposes novel beam control technique to coexist with the terrestrial networks in Q band. The proposed method controls satellite’s transmitting antenna boresight adaptively to maximize signal to noise power ratio of satellite ground station and minimize interference to terrestrial networks. The effectiveness of our proposal is verified through simulation results. |
