Abstract:

The satellite RF system is an essential part of the control and management of a satellite from the ground station and provides a communication link during the entire satellite mission life. The RF system should be fully evaluated for reliability and stability on the ground, as defined by the requirements of the satellite mission. The evaluation of an RF system can be verified by measuring the RF link parameter and then comparing and analyzing the result with the RF system requirements. Since the system test for satellites requires advanced technology and has a high cost with limited time, however, it is difficult to access technically for many parts. This paper describes the design and verification of the RFTS (Radio Frequency Test Set) and the RTS (RFTS Test Software), which AITC developed in KARI to evaluate a satellite RF system. The developed test system was used to perform an RF functional test on an ETB (Engineering Test Bed), and the RFTS’s full functions were debugged to provide a reliable function for the KOMPSAT-2 Satellite Test. The RFTS showed a high degree of reliability, conformity and repeatability for each test case at any time. It is now being applied to the RF system evaluation test of KOMPSAT-2 FM during KOMPSAT-2’s integration and environment test phases. Hereinafter, this system can be applied to the next generation of satellites as well as to the RF payload system as a unique KOMPSAT series RF test system.
