A comparison of model estimates of ocean-tide loading displacements in New Zealand
We analyze the regional accuracy of the global ocean tide models TPXO7.2, GOT00.2, NAO.99b, FES2004, and EOT10a using the tide-gauge records from 7 stations along the coastline of New Zealand. The comparison reveals that TPXO7.2 provides the bestfit with the tide-gauge data in this part of the world. The TPXO.7.2 ocean tide model is then used for computing and analysis of the vertical and horiz...
متن کاملEstimates of Minor Ocean Tide Loading Displacement and Its Impact on Continuous GPS Coordinate Time Series
The site displacement due to ocean tidal loading is regarded as one of the largest uncertainties in precise geodetic positioning measurements, among which the effect of minor ocean tides (MOT), except for the 11 main tidal constituents, are sometimes neglected in routine precise global positioning system (GPS) data processing. We find that MOT can cause large vertical loading displacements with...
متن کاملDetecting andmitigating ocean tidal loading displacements in the Bay of Fundy using GPS
Tidal induced displacement is one of the systematic errors that contribute to the scatter in the geodetic measurements derived from the GPS system. This paper focuses on ascertaining and reducing tidal induced errors due to ocean tide loading (OTL) at two GPS sites, namely CGSJ (Coast Guard Saint John, New Brunswick) and DRHS (Digby High School, Nova Scotia), established under the Princess of A...
متن کاملGPS & GLONASS RX - theory
Besides amateur-radio satellites, the most interesting satellites for radio amateurs are weather (imaging) satellites: radio amateurs have successfully built weather-satellite image reception equipment for all known weather satellites and all known image transmission standards. Radioamateurs also pioneered satellite TV reception using small antennas much earlier than this became a mass-produced...
متن کاملCombined GPS/GLONASS Precise Point Positioning with Fixed GPS Ambiguities
Precise point positioning (PPP) technology is mostly implemented with an ambiguity-float solution. Its performance may be further improved by performing ambiguity-fixed resolution. Currently, the PPP integer ambiguity resolutions (IARs) are mainly based on GPS-only measurements. The integration of GPS and GLONASS can speed up the convergence and increase the accuracy of float ambiguity estimate...
