High Accuracy GPS Surveys with Mixed Receivers and WVR's

使用全球定位系统的潜力 地球物理学和大地测量已经证明， 在最近的一些研究中，显示基线精度为0.1- 0.01 ppm. GPS的成功使得越来越多的 对地球仪的构造研究，创造了一个前所未有的 增加对更多接收器的需求以补充和替换 现已停产的TI4100接收机。 这促使 开发了一些新的，更便携，成本更低， 也许更精确的GPS接收器。 PI将系统地 测试新的GPS接收机和天线设计，以确定如何 各种工具可以结合在一个运动中， 失去了以前用单个接收器获得的高精度 数据 新天线的多路径特性将 比较了

The potential of using the Global Positioning System (GPS) for geophysical and geodetic measurements has been demonstrated in a number of recent studies showing baseline accuracies of 0.1- 0.01 ppm. The success of GPS has led to a growing number of tectonic studies around the globe and has created an ever- increasing demand for more receivers to supplement and replace the now discontinued TI4100 receiver. This has prompted the development of a number of new, more portable, lower cost, and perhaps more accurate GPS receivers. The PIs will systematically test new GPS receiver and antenna designs to determine how various instruments can be combined in one campaign without losing the high accuracy previously obtained with single receiver data. The multipath characteristics of the new antennae will be compared.
