多线程技术在GNSS数据并行解码中的应用

摘要

With the application of GNSS technology in people’s daily life and engineering construction is becoming more and more extensive ,efficiency and accuracy requirements for data processing are also increasing .This paper introduces the data format of RINEX and ZHD Q5 ,then analysis of the algorithm flow about original data and observations navigation message converted to RINEX standard format by decoding ,multithreading technology is introduced to realize real‐time parallel decoding of observation data in multi stations .T hrough programming and actual testing ,the feasibility of the algorithm is verified in engineering application .%随着GNSS技术在日常生活以及工程建设方面的应用日益广泛，对数据处理的效率和准确性的要求也越来越高。介绍RINEX标准数据格式以及中海达Q5接收机二进制数据格式，研究将原始观测值数据以及导航电文通过解码转换为RIN EX标准格式的算法流程，并引入多线程技术实现多测站观测数据的实时并行解码。通过编程以及实际测试，验证该算法在工程应用中的可行性。
