Research and Implementation of Ground Station Software System with Highly Automation

摘要

An experimental ground station (EGS) for the scientific experimental nano-satellite THNS-1 is developed. Great efforts are made to fulfill a highly automated, normally unmanned and low-cost EGS. The software system is designed with modularization, hierarchy and multi-mission concept. Monitor & control as well as scheduling of all resources have been centralized to track-management module and the remotely controlled ground station is normally unmanned. The azimuth/elevation (AZ/EL) parameters for antenna to track satellites are sent by computer after calculating in real time, which greatly reduces the cost of antenna system. Software control mode also solves the problem how the antenna tracks satellites continuously when a 2-axis antenna's elevation is near 90 degrees.
