The present invention relates to a passive microwave sounder for a satellite, having a fixed reflection plate. The passive microwave sounder for a satellite, having a fixed reflection plate includes: a motorincluding a first rotary shaftformed to extend in a progressing direction of a satellite; a first rotating reflection plateforming a predetermined angle with respect to the ground surface of a nadir direction and having a first one-side surfaceand a first other-side surface, the center of the first one-side surfacebeing coupled to and rotating with the first rotary shaft, such that the first one-side surfaceand the first other-side surfacealternately face the ground surface, and the second other-side surfacereflecting incident electromagnetic waves; an auxiliary reflection partreflecting the electromagnetic waves incident from the first other-side surfaceto a predetermined position; a reception partreceiving the electromagnetic waves reflected from the auxiliary reflection part; and a fixed reflection platefixed above the first rotating reflection plateat a predetermined angle with the ground surface and reflecting the electromagnetic waves to the first one-side surfaceor the first other-side surface
