| 摘 要： | 紧组合技术是当前惯性/卫星组合导航技术的发展趋势,而惯性/卫星伪距/伪距率组合导航算法是紧组合技术的基本算法。本文提出了一种惯性/卫星伪距/伪距率的组合导航算法的实现方法,并采用惯导和接收机的动态数据进行了离线仿真,仿真结果表明,本文提出的伪距/伪距率的组合导航算法直接采用接收机测量的伪距、伪距率信息作为观测量,能够准确估计惯导误差,消除了量测输入的相关性问题,尤其是在GPS卫星数为2时仍能保持较高的导航精度,为惯性/卫星紧组合技术的进一步研究奠定了基础。

| Abstract: | A INS/GPS integrated navigation method in pseudo range and pseudo range rate is basic in tight-integrated technology which is a trend in the field of INS/GPS integrated navigation now.In this article,a INS/GPS integrated navigation method in pseudo range and pseudo range rate is proposed,by which the data from a INS and a GPS receiver is simulated off-line.The result shows that,the method can nicely estimate INS error with the raw information of pseudo range and pseudo range rate from a GPS receiver,and can... |
