Design and Development of Ground Station Network for CubeSats Constellation, Joint Global Multi-Nation Birds

摘要

BIRDS project ground station network is designed to support the communication systems of four BIRDS CubeSats by connecting the seven ground stations of each member countries by internet to increase the communication time between ground station and satellite. The network operation can increase the downlink data throughput. Moreover, the ground station network is able to facilitate the determination of precise satellite location, analyzing time of arrival of satellite signal among multiple ground stations. During the operation time, each ground station shall access the operation plan preprogramed in the central server, and uplink a set of command to CubeSats, as well as receive mission data from CubeSats by using the satellites tracking system. Afterwards, the received mission data will be stored in the central database.
