Integrated Telemetry System for Small Space Vehicle

传统遥测系统存在组成设备多、重量重、安装空间大、接口和电缆网复杂等不足,无法满足小型空间飞行器对重量、尺寸、飞行时序的灵活设计、遥测数据的事后处理等新的需求。针对该问题,提出了一种小型空间飞行器集成化遥测系统设计方法。该方法采用综合电子集成技术、循环下传设计、混合编帧和事后数据拼接处理方法,设计并实现了一种小型集成化遥测系统。地面及飞行试验表明,该系统降低了重量、尺寸和功耗,极大地降低了数据丢帧率,提高了无线传输系统的可靠性。该技术对于体积和重量要求苛刻的小型空间飞行器,具有良好的应用前景和推广价值。

The traditional telemetry system has many shortcomings such as multiple components,heavy weight,large installation space,complicated interface and cable network,which can not meet the new requirements of small space vehicles for weight,size,the flexible design of flight sequence,and the post-processing of telemetry data.To solve these problems,a design method of integrated telemetry system for small space vehicles is proposed,which adopts integrated electronic integration technology,cyclic download design,hybrid framing and post data splicing processing methods to design and implement a small integrated telemetry system.Ground and flight tests show that the system reduces the weight,size and power consumption,and also greatly reduces the frame loss rate of data,and improves the reliability of wireless transmission system.This technology has a good application prospect and promotion value for small space vehicle with strict volume and weight requirements.
