摘要:

针对传统遥测系统多设备、复杂电缆连接架构无法满足小型空间飞行器对小体积、轻重量、自主化程度高的遥测系统需求的问题，提出了一种小型空间飞行器通用化遥测系统设计方法。该方法引入集成化、模块化设计理念，采用混合编帧、双时序设计和故障自检测等方法，设计形成了一种通用化架构，包含了多种硬件模块和软件单元，集成于遥测综合装置，满足了空间飞行器小型化轻量化要求，系统时序灵活，自主化程度高。地面和飞行试验表明，该方法可快速适配小型空间飞行器需求，体积小、重量轻，具有良好的应用前景和推广价值。

Abstract:

With the development of space vehicle, telemetry system becomes dimension limited, while the design period of system has been shortened obviously and traditional telemetry system can hardly meet the demand. In order to solve these problems, a miniaturized and modularized telemetry system is designed and implemented. Based on the analysis of telemetry system, most of the telemetry functions have been realized in several modules. With these modules, one device called telemetry kernal device is implemented that makes telemetry system very small and light. In addition, high integration and adaption design makes telemetry system applied to other space vehicle easily. Recent tests show that this telemetry system is well applied to new space vehicle to acquire the flight test data. The prospect of this telemetry system can be attractive both in application and promotion.
