Analysis of GNSS IDM Situation and Its Revelation to Us

摘要

In this paper, cases of GPS and Galileo interference are introduced, and situation of IDM in America and Europe is studied. As a widely used system, GPS is often reported to be interfered in the world. Many researches on interference and countermeasures have been implemented in different departments of US. Now a collaborative IDM plan which integrated all related department is being developed and implemented. Europe has not only developed such kind of IDM plan for GPS but paid much attention to IDM during each step of Galileo's development. Similarly, Beidou is also easily affected by RF interference. So it is necessary to start the research of IDM in China for GNSS including Beidou, and planning from all aspects such as policy, management, institution setting etc. as soon.
