The invention provides a passive vibration isolation layout method for micro-vibration suppression of an optical remote sensing satellite and the satellite, and the method comprises the steps: carrying out the layout of an on-satellite micro-vibration source according to the micro-vibration spectrum and magnitude, and transmitting the micro-vibration magnitude of a bottom plate of a satellite to a layer plate, a side plate and a top plate from the bottom to the top, the transmission attenuation characteristic that the attenuation degree is increased in sequence isolates the influence of micro-vibration of on-satellite moving parts on micro-vibration of remote sensing loads. According to the passive vibration isolation layout method, vibration isolation is achieved through the star structure, a vibration isolation device does not need to be added, interference of micro-vibration of the satellite can be effectively weakened, the vibration reduction effect is remarkable, and technical support is provided for high-precision and high-stability work of the optical remote sensing satellite.
