With the rapid development of satellite navigation technology, the application fields of GNSS receivers are also extending. In various military and civil application scenarios, the complex electromagnetic environment will affect the performance of the GNSS receivers, and even make receivers work improperly. Therefore, it is important to test the performance of the GNSS receivers in the complex electromagnetic environment by adaptability test, and it is also a research hotspot in recent years. Based on the analysis of the concept of complex electromagnetic environment, this paper discusses key issues in complex electromagnetic environment adaptability test of GNSS receivers, such as the construction and evaluation of complex electromagnetic environment, adaptability test procedures, test evaluation method, and so on. The research achievements may provide technique reference for the further research on the adaptability test of GNSS receiver in complex electromagnetic environment.
