Design of telemetry acquisition and monitoring system for the transponder of communication & broadcasting satellite (CBS) payload system

摘要

KAI has been participated in ETRI program of EQM (Electrical Qualification Model) development in the communication and broadcasting satellite Ku and Ka bands payload systems. This paper describes the design overview of the telemetry acquisition and monitoring system for the transponder of Communication & Broadcasting Satellite (CBS) Payload System at the ground test period. Also, the telemetry acquisition hardware, telemetry formatting and decoding techniques are specified in the paper. The system is divided into two parts that are the Bus Controller (BC) Station for monitoring control and display of telemetry data, and the Remote Terminal (RT) Unit for telemetry raw data acquisition. And, the system adapts the MILSTD-1553B interface for telemetry data transfer between BC Station and RT Unit. Both parts are designed appropriately to meet the functional and interface requirements, which is to avoid damaging the EQM equipment during test.
