description The invention relates to a sky area fixed star simulator with a high-precision inter-satellite angular distance and a calibration method thereof, and aims to solve the technical problems of high difficulty in assembling and adjusting a single-satellite simulation component, low working efficiency and poor star point angular distance stability of the conventional sky area fixed star simulator. The sky area fixed star simulator comprises a control system, a mounting base, a two-dimensional adjusting mechanism, a supporting structure, a plurality of single star simulation assemblies and an alignment assembly, the working face of the supporting structure is of a spherical structure, and the single-star simulation assemblies are fixed to the working face of the supporting structure. Each single-star simulation assembly comprises a lens cone, a mounting flange, an object lens frame, a double-optical-wedge lens frame, a double-optical-wedge optical element, a star point plate structure and a rear cover.
