GPS实验报告
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:
