The positional deviation of the Automatic Emergency Call System (AECS) under collision conditions brings difficulties for post-rescue operations. Currently, there is a lack analysis on system operating during collisions in reliability assessment methods Global Navigation Satellite (GNSS) deployed AECS. Therefore, this paper establishes an in-vehicle environment simulation model emergency calls to explore influence parameters such as temperature and vibration data simulated GNSS system. We also propose environmental limits applicable comprehensive AECS tests, which can objec-tively evaluate provide support bench test. Through satellite signal-based semi-physical simulation, subjected test different conditions. findings study demonstrate that occurrence random vibra-tion impact stress, induced by vibration, exerts considerable disruptive effects signal collisions. Consequently, it leads substantial interference with accurate detection post-collision positioning information. When operates 2.4gRMS condition, maximum phase noise error 8.95%, does not meet accuracy requirements. On other hand, semi-simulation less affected changes, at allowable dif-ference equipment, 2.12%. based variation nec-essary are obtained, including consistent vector generator Power Spectral Density (PSD) lower than 1.2gRMS.
