基于分包体制的卫星遥测信息流设计

Design of information flow in satellite based on packet telemetry

随着FPGA、ASIC技术在卫星遥控遥测领域的广泛应用,使得地面对卫星遥测的动态性能得到很大改善的同时,地面接收到的遥测数据量也急剧增加,目前基于PCM的遥测信息流体制已经逐渐不能满足现行卫星遥测的需求,提出了基于CCSDS标准下的分包体制的遥测信息流设计思想,在详细分析分包遥测特点的基础上,结合卫星动态管理实现的要求,给出了分包遥测的具体设计方案及应用方法。

With the FPGA and ASIC technology widely used in the TY＆C field of satellite, making the dynamic performance of the ground station receiving the satellite telemetry has been greatly improved, but it also leads to a sharp increase in the telemetry and tele-control data, so based on the traditional PCM system can not meet the demand for current satellite of telemetry. This article proposed a design thought of packet telemetry based on the CCSDS standards, after analyzing the features of packet telemetry thought deeply and combining the demand of dynamic management in satellite, it presents a detailed program and application method.
