Abstract
In order to maintain international competitiveness while meeting the growing demand for PNT services on a global scale,the United States continues to upgrade and transform its modern Global Positioning System(GPS).One of the key improvements is to launch and broadcast a new civilian signal L1C in 2020.In response to the increasingly fierce competition for spectrum resources in the new situation,based on the basic characteristics of the four civilian GPS signals,this paper elaborates on the background and sig-nificance of selecting L1C frequency point signals,analyzes the basic structure of the signal,focuses on the specific modulation meth-ods and important features of L1C signals,and finally conducts a detailed analysis of pseudocodes.Through in-depth analysis of the L1C signal system,it has reference value for the design and engineering implementation of other GNSS future new system signals.关键词
