Abstract
Within the next few years the efficiency of high-precision Global Positioning System (GPS) surveys will increase by nearly an order of magnitude with the introduction of lighter-weight and lower-power instruments, the application of kinematic techniques, and the availability of an improved satellite constellation for most areas of the world. There may also be a significant improvement in accuracy from higher data rates and the removal of setup errors with permanently mounted antennas. Much of our knowledge of the capabilities of the system has derived from analysis of static surveys in the southwestern United States, a region for which the Block I constellation has been optimized. This region also includes a large number of sites whose relative positions have been measured independently by the NASA Crustal Dynamics Project and the National Geodetic Survey (NGS) using fixed and mobile very long baseline interferometry (VLBI) systems. By reviewing what has been learned from the five major campaigns and a similar number of smaller ones in California, we attempt to provide a context for surveys which have been and will be carried out in other parts of the world. To complement the review by Beutler and Gurtner (this volume), we concentrate on regional networks, with baselines between 50 and 1000 km.
