GPS在道路桥梁工程测量中的应用论文

摘 要GPS 技术是当今信息社会进展最快的技术之一，GPS 定位技术以其速度快、精度高、全天候、不受通视条件限制、费用省、操作简便等优良特性被广泛应用于控制测量中。时至今日，可以说 GPS 定位技术已完全取代了用常规测角、测距手段建立控制网。我们一般将应用 GPS 卫星定位技术建立的控制网叫 GPS 网。归纳起来大致可以将 GPS 网分为两大类：一类是全球或全国性的高精度 GPS 网，其主要任务是做为全球高精度坐标框架或全国高精度坐标框架，为全球性地球动力学和空间科学方面的科学讨论工作服务，或用以讨论地区性的板块运动或地壳形变规律等问题。另一类是区域性的 GPS 网，包括城市或矿区 GPS 网，GPS 工程网等，这类网中的相邻点间的距离为几公里至几十公里，其主要任务是直接为国民经济建设服务。本文通过利用 GPS 对实地进行数据采集，并得出使用 GPS 测量具有效率高、费用省的结论。关键词:GPS 测量，工程测量，GPS 静态定位测量，动态 GPS 实时定位AbstractGPS technology is one of the fastest growing technology in today's information society, GPS positioning technology for its speed, precision degree is high, the all-weather, without being limited by the visibility conditions, cost, simple operation and other excellent features are widely used in large ground control survey. Today, to say the GPS positioning technology has been completely replace the conventional measuring Angle, measuring means to establish the control network. We usually apply the GPS satellite positioning technology based GPS control net is called net. Can be roughly classified into the GPS network can be divided into two categories: a class of high precision GPS network is global or national, its main task is to as a global high-precision coordinate frame or by the national high precision coordinate frame, for global geodynamics and space science scientific research work of the service, or to the research of regional tectonic movement or crustal deformation law and so on.
