%X With the developments of satellite,radio communication,and computer technology,autonomous operation of satellite navigation system becomes more and more important.Inter-satellite Link(ISL) is a key technology.The Walker constellation structure,and its categories,frequencies and rules of inter-satellite links are introduced.Besides,the construction method and visibility of inter-satellite links of Walker constellation are analyzed and then,the azimuth,elevation,and range are computed as well.Study shows that multiple ISLs can be built in Walker constellation.
