With the increasing demand of data acquisition, the original telemetry channel tends to be saturated. A design scheme of small telemetry data acquisition and storage device is proposed. This device uses FPGA as the core control module and FLASH as the storage medium, and is used for signal acquired, framed and stored. Several reliability design measures such as location identification, paging storage and redundancy design are also adopted. The device solves the problem of insufficient residual amount of existing telemetry channel in a low-cost way. It has the characteristics of being easy-design, recyclable and small in volume, providing effective data support for the design and improvement of subsequent launch vehicles, and has high universality and reliability. 數據采集；存儲；FLASH data acquisition; storage; FPGA 劉倩,李雷,張永杰,李芳培 上海宇航系統工程研究所 jsjclykz/article/abstract/201906220628
