| 摘 要： | 结合三台Trimble4000se型单频GPS接收机检测实例,提出了GPS接收机内噪声水平分布统计的评价方法,以及在超短基线场内GPS接收机内噪声水平的检测方法——多时段旋转检测台法、实例测试,按本论文方法得到的被测试GPS接收机内噪声水平标准差为0．38mm。由测试实例得到如下结论:GPS接收机内噪声水平评价方法以及检测方法更加合理、可信;在超短基线场内多时段测得的同一基线长度互差应小于2mm;GPS接收机系统软件对内噪声水平有着非常重要的影响。

| Abstract: | Combined with test of three Trimble4000se GPS receivers,this paper puts forward a method of evaluation on interior noise level using Chorology and Statistics and a new testing method by revolving the horizontal table-board between multi-sessions on the field of Mini-baseline.According to the method of this paper,the standard deviation of interior noise level of the tested GPS receivers is 0.38mm.Through the case, we can draw the following conclusion:First,the method of appraisal and testing of this paper is... |
