摘　　要：针对工程建设中对施工人员的安全需求,结合GNSS接收机的性能,提出了基于GNSS反向差分技术的工程施工人员监控系统构建。讨论了基于GNSS反向差分技术监控系统中的关键问题,包括时间校准、反向差分原理和卡尔曼滤波算法。提出了导航芯片性能的评估方法,并对三种不同的导航芯片的特性进行测试和评估。结果表明,有天线的导航芯片的定位精度高于无天线的导航芯片。基于构建的软件系统,进行数据测试,结果表明,对应平面精度可以达到:E方向0.3253m,N方向为0.3946m。Considering the safety requirements of workers in construction and the characteristics of GNSS receivers,a monitoring system based on GNSS inverse differential is proposed. The key problems of this monitoring system such as time calibration,the principle of inverse differential and the Kalman filter algorithm have been discussed. The method of estimating the performance of navigation chips is proposed and three different kinds of navigation chips are used for test and evaluation. The results show that the precision of navigation chips which have antennas are better than those do not have. Testing the data based on the created software system,the results show that the horizontal accuracy can reach 0. 3253 m in north and 0. 3946 m in east.
