Abstract: The vibration signal collection system based on FPGA+1553B can realize the high-precision measurement of the satellite chatter,which is directly related to the chatter measurement and vibration compensation caused by the vibration of the actuating mechanism impacted by dust when the satellite is working in the satellite space,and is of great significance for improving the ground resolution image correction of remote sensing satellite.In this paper,based on the architecture of FPGA and 1553B bus,a data acquisition system for in-orbit satellite flutter measurement is designed.The key problems of the system,such as multi-channel synchronous acquisition,storage and transmission as well as anti-radiation reliability,are analyzed and designed in detail.The function of the system is verified by hardware design and experiment.The test results show that the prototype of the data acquisition system involved meets the requirements of the spaceborne test.

Key words: Spaceborne, Synchronous data acquisition, 1553B, Radiation resistance, Triple module redundancy
