Remote Dynamic Reconfigurable Telemetry Encryption Transmitter Design and Implementation

近年来,随着我国航天器新型号的发展及国产化进程的推进,综合考虑高度集成化、远程动态可重构的遥测设备需求,研制兼容多调制体制的远程动态可重构遥测加密发射机是研制遥测传输设备的必然趋势。区别于传统发射机基带软件架构的FPGA+DA+信道方式,该发射机架构由异构多核FMQL(可编程芯片)嵌入式系统+射频集成芯片B9361组成发射机基带组成,结合软件实现远程动态可重构、上电自检、工作状态巡检、工作状态实时上报功能,提高了测量系统集成度,最大程度地实现软硬件资源的重构和共享,也大幅度缩减了系统体积、重量、功耗和成本。本方案基于通用化、系列化、组合化的设计思想,使发射机产品具备高度集成化、元器件自主可控、通用化平台、软件灵活配置等优点,为新一代遥测发射机向通用化、高性能、动态可重构方向发展提供有力的技术支撑。

In recent years,with the development of new models of China's spacecraft and the advancement of the localisation process,considering the demand for highly integrated and remotely dynamically reconfigurable telemetry equipment,the development of remotely dynamically reconfigurable telemetry encrypted transmitters compatible with multiple modulation regimes is an inevitable trend in the development of telemetry transmission equipment.Differing from the traditional transmitter baseband software architecture of FPGA+DA+channel approach,the transmitter architecture consists of a heterogeneous multi-core FMQL embedded system+RF integrated chip B9361 to form the transmitter baseband.This is combined with the software to achieve the functions of remote dynamically reconfigurable,power-on self-test,working status patrol,and real-time reporting of the working status.This improves the degree of integration of the measurement system and realizes the reconfiguration and sharing of the software and hardware resources to the maximum extent.It also significantly reduces the system volume,weight,power consumption,and cost.This scheme is based on the design ideas of generalization,serialization,and combination,so that the transmitter product has the advantages of high integration,serialization,and controllable components,generalized platform,flexible software configuration,etc.This provides strong technical support for the development of the new generation of telemetry transmitters in the direction of generalization,high performance,and dynamic reconfigurability.
