摘要
分析了伽利略系统的频率结构和信号设计、性能及干扰,阐明了伽利略系统的频率和信号设计比GPS更具优势。伽利略系统在E5a/L5和E2-L1-E1载波上,使用与GPS相同的中央频率,可提高GNSS接收机用户的互用性,因此具有更广阔的发展前景。
Analyzing the Galileo frequency structure and signal design,performance and interference,this article demonstrates the presented Galileo frequency and signal plan is superior to GPS.Using common centre frequencies with GPS on E5a/L5 and E2-L1-E1 will enhance interoperability for the future user of an integrated GNSS.So it will promote the development of Galileo applications.
