According to Korea's mid-and long-term plan, launch vehicle technology is rapidly developing for the launch space powers starting with NARO in 2009 through Nuri in 2020. and LEO satellite technology is rapidly developing for the space powers starting with KITSAT-1 in 1992 and starting with Arirang 1 through Arirang 3 A.
As Korea's science and technology develops, it has been utilized in various fields, such as satellite launches and payloads for performing imaging missions. Telemetry Ground station performance verification is very important. To this end, it is necessary to automate equipment for monitoring, control, and performance verification tests.
Therefore, in this study, remote data receiving equipment is monitored and controlled in real time, and information on the ground station is managed. It analyzes the equipment status and outputs it to the screen when a problem occurs, and implements the performance verification test function for measuring the bit error rate, link budget, servo test, and antenna gain. Using satellite orbit information, a low-orbit satellite tracking function and an automated function for performing projectile missions were implemented, and a system was constructed to enable comparative analysis by recording surveillance control information.
In this study, a system was constructed to manage a total of five ground stations, the Goheung Naro Space Center, two Jeju tracking stations and two Palau Republics. At this time, remote monitoring and control functions, authority functions, and key parameter functions were implemented to enable operators to use multiple ground stations.
In this study, the implementation items and equipment communication interfaces were analyzed to develop an automated system for the performance verification test of the space station, and based on this, the system was designed with design modeling definition, use case modeling, and component modeling. After the implementation of the function with the design details, the development was completed by performing equipment monitoring control test, performance verification test, remote authority setting and monitoring control test, and ground station interlocking test for each local ground station.
The system of this study will be used to carry out the mission of the Korean projectile and the projectile project of the National Space Research Center in France. When evaluating performance verification for communication between a space-ground station system and a projectile or low-orbit satellite, it can be applied in consideration of the operating concept and is expected to be applicable to various fields.
