摘要
针对微小卫星对星载通讯分系统高数据量,高速率和高可靠的要求,本文根据设计指标,采用以arm为内核的STM32F4芯片为主控制器,以及高输入范围,低辐射的转压稳压芯片和满足性能要求射频模块,在查阅大量文献资料之后,设计了一款基于arm内核的UV通信机。经过仿真和调试,上下行通信链路通畅,指令响应良好,容错性能较好,没有出现死机状况,通信机基本满足指标要求。该通信机已经具备基本功能且已通过合作方初样验收,效果良好。
The communication subsystem for small satellite of high data volume,high speed and high reliability arerequired.this paper uses ARM core＇s product STM32 as the main controller,high input range,low radiation voltage regulator chip and RF modules that meet performance requirements.A UV communication device is designed after reviewing a large amount of literature. After simulation and debugging,the uplink and downlink communication link is still very smooth and the command response is good with no crash situation and good fault tolerance. Communication device met the basic requirements of indicators.The communication device already has the basic functions and has passed the acceptance of the partners. The effect is acceptable.
