Real-time GPS sensing of atmospheric water vapor: Precise point positioning with orbit, clock, and phase delay corrections
The recent development of the International Global Navigation Satellite Systems Service Real-Time Pilot Project and the enormous progress in precise point positioning (PPP) techniques provide a promising opportunity for real-time determination of IntegratedWater Vapor (IWV) using GPS ground networks for various geodetic and meteorological applications. In this study, we develop a new real-time ...
متن کاملGPS Meteorology' Remote Sensing of Atmospheric Water Vapor Using the Global Positioning System
We present a new approach to remote sensing of water vapor based on the global positioning system (GPS). Geodesists and geophysicists have devised methods for estimating the extent to which signals propagating from GPS satellites to ground-based GPS receivers are delayed by atmospheric water vapor. This delay is parameterized in terms of a time-varying zenith wet delay (ZWD) which is retrieved ...
متن کاملReal-time Water Vapor Sensing with Suominet -- Today and Tomorrow
SuomiNet, a university-based GPS network provides real-time atmospheric sensing capability via the Internet for research and education. SuomiNet is funded by the U.S. National Science Foundation and university costshare, and is managed by the University Corporation for Atmospheric Research (UCAR). We present examples of real time PW data products currently provided by SuomiNet, and describe rea...
متن کاملReal-Time Water Vapor Maps from a GPS Surface Network: Construction, Validation, and Applications
In this paper the construction of real-time integrated water vapor (IWV) maps from a surface network of global positioning system (GPS) receivers is presented. The IWV maps are constructed using a twodimensional variational technique with a persistence background that is 15 min old. The background error covariances are determined using a novel two-step method, which is based on the Hollingswort...
متن کاملReal-Time Interference Detection in Tracking Loop of GPS Receiver
Global Positioning System (GPS) spoofing could pose a major threat for GPS navigation ‎systems, so the GPS users have to gain a better understanding of the broader implications of ‎GPS.‎ In this paper, a plenary anti-spoofing approach based on correlation is proposed to distinguish spoofing effects. The suggested ‎method can be easily implemented in tracking loop of GPS receiver...
