摘要
GPS现代化的一个重要内容就是增设第三民用频率L5，它采用一个全新的功能更强的信号结构．本文主要研究了L5导航电文的编码及其纠错技术，并根据现有的资料，对L5导航电文进行了编码仿真．
One of the most important contents in GPS modernization is adding the third civil signal L5. In this thesis, we focus our attention on the encoding of L5 data structure. One of the important parts is the realization of CRC algorithm, which is presented in detail in the paper. What＇s more, we used the L1 and L2 navigation message available to simulate a message frame of L5.
