摘要: Multipath and atmospheric effects can limit GPS surveying precision. We surveyed a 43 km baseline using large diameter choke ring antennas to reduce multipath pointed radiometer barometric data correct for slant delay. Based on 11 daily solutions, delay corrections improved vertical precision 1.2 mm rms horizontal sub-mm. Applications high include deformation monitoring associated with earthquake volcanic processes, subsidence, isostasy, sea level measurements; of water vapor climate global change research, improve the resolution synthetic aperture radar; calibration satellite altimeters; precise orbit determination.
