Performance of the proto-flight model of the onboard packet switch for the engineering test satellite VIII

摘要

An onboard switch enables satellite communications systems with a multi-beam structure to operate more efficiently. A proto-flight model of the onboard packet switch with the function as bridges has already been developed. The adoption of the function as bridges for the onboard switch make it possible that the highly flexible network is constructed. The performance test results show that the onboard packet switch is sufficient to meet the requirements for the mobile satellite communications system. This onboard packet switch will be installed in the Engineering Test Satellite Eight (ETS-VIII) which is planned to be launched in 2004.
