星上业务综合与地面综合基带一体化设计的思路

Integrated design of service integration and baseband synthesis

为满足在航天器与地面站之间传输各类数据的要求 ,航天器和地面设备都有相应的措施与之适应。星上数据的业务综合将航天器上的各类数据合并成一路数据流 ,经物理信道统一传输。地面设备则将遥测、遥控、测距和数传等功能在基带集成 ,形成综合基带设备。业务综合与综合基带都曾推动了航天任务中数据传输系统的发展 ,但二者都是从自身的角度考虑 ,并没有作为一个系统综合设计。本文对业务综合与综合基带进行一体化设计 ,使天地系统相互协调 ,最大限度地提高星地数据传输的可靠性和有效性。

To satisfy the requirement of transferring data between aircraft and ground station,some means are provided on aircraft and ground equipments respectively.Service integration on board mixes the data into a data stream and transmitted by physical channel.Synthetical baseband equipments integrate the functions of TT&C and data transmission on the baseband.Both service integration and synthetical baseband has advanced the development of data transmission system in space mission,but they both consider from their own point of view and are not designed on the whole.In this paper,service integration and baseband synthesis integrated design harmonizes the aircraft system and ground system,and improve the performance of data transferring system as much as possible.The idea of integrated design is demostrated by a data system of remote sensing satellites.
