地理与生物信息学院

2016/2017学年第1学期

实验报告

课程名称：

卫星导航系统

实验名称：

仙林校区GPS控制网布设

班级学号

学生姓名

指导教师

日期：

2016年12月

一、实验目的：

掌握GPS外页测量过程中应注意的事项及有关精度要求

2、实验内容：

进行仙林校区GPS控制网布设，并进行外页观测，通过相关软件对所采集的样本进行基线解算和网平差

3、实验过程：

1>对仙林校区进行测区划分，并进行分组，以及分配人员

2>安置GPS接收机，对中，整平，量取仪器高，要求各组同时开机，开机观测一个半小时，同时关机

3>到室内传输数据，通过相关软件对所采集的样本进行基线解算和网平差

4、实验结果：
