Abstract

With the growing maturity of millimeter wave technology and high-throughput satellite communication technology

as well as the urgent need for global broadband communication services

the construction of LEO giant communication constellation has attracted great attention

and up to thousands of satellites have been deployed.A large number of LEO communication satellites have realized multiple and repeated coverage of high-frequency radio frequency signals on the ground.At the same time

ground communication resources provide a hardware platform for signal reception and create conditions for the development of integrated communication and navigation.The status quo

opportunities and challenges of the integrated LEO navigation constellation were discussed

and the differences of resources required by the integrated LEO navigation constellation and the global navigation satellite system were emphatically expounded.In terms of space segment

ground segment and user segment

the conclusions and prospects for future research were presented.
