Application and Development Trend of Solid State Recorder in Spacecrafts

星载固态存储器是各类航天器的基本配置设备,特别在遥感卫星领域,记录设备的成功运行是航天器完成任务的前提条件。星载记录设备已从模仿磁带机的简单工作模式发展为支持复杂文件系统、多用户、多维检索的智能工作模式,设备的存储容量、码率和工作寿命均有质的飞跃。对星载记录设备在各类航天器中的应用及技术发展情况进行总结,并对其发展趋势进行探讨。

On-board solid state recorder is the basic equipment for all kinds of spacecrafts, especially in the remote sensing satellite fields. The successful operation of the recorder is one of the preconditions for spacecrafts to finish the task. On-board solid state recorder has developed from the simple operation mode of simulating tape recorder to the intelligent operation mode which supports the complicated file system, multi-user and multi-dimensional retrieval. The data storage capacity, rate and operating life of the solid state recorder has obtained great achievements. In this paper the application status and technology development of on-board solid state recorder in all kinds of spacecrafts are summarized, and its development trend is discussed.
