Sommario/riassunto |
|
This book presents selected research papers from China Satellite Navigation Conference (CSNC) 2024, held in Jinan, China, on 22–24 May 2024. These papers discuss the technologies and applications of the Global Navigation Satellite System (GNSS) and in particular the latest advances in the China BeiDou System (BDS). They are divided into 8 topics to match the corresponding sessions at CSNC 2024, which broadly covered key topics in GNSS. Readers learn about the BDS and keep abreast of the latest advances in GNSS technologies and applications. |
