为解决卫星电子系统小型化的问题,本研究介绍了一种应用于卫星遥测遥控通道的FPGA设计和实现。与传统设计采用LSI、MSI电路比较,新的设计借助FPGA的大容量、低功耗、高速度等特性,使用了多冗余、纠检错等方法,实现了适应性更强、可灵活配置的更健壮的遥测遥控子系统,并得到试验验证。说明通过电子集成技术应用,系统的性能大为提高,特别在体积、重量、功耗、可靠性、空间适应性等方面有显著的优势。研究表明了FPGA应用于星载计算机,具有现实意义。

For the miniaturization of satellite electronic system, the paper introduces design and implementation of satellite telemetry and telecontrol channel based on FPGA . In general, the conventional hardware circuit design of the sub - system uses the LSI or MSI technology. Along with the rapid development of VLSI technology, the FPGA is applied to the design with the high integration and performance, i.e. high logic capacity, high speed and low power consumption. By the method of redundancy and Error Correction Control, we implement flexible and configurable design that meets the requirements of different applications. Applications of FPGA have the advantages of the volume, weight, power consumption, radiation-hardened and reliability. It is proved that applications of FPGA in on-board computer are important.
