چکیده
The ultra-rapid satellite clock product based on the batch estimation is commonly used for high-precision and reliable precise point positioning (PPP) services. In order to clarify effect of different ranging errors accuracy, source bias induced by observation model classified into initial (ICB) time-dependent (TDB). addition ICB TDB, analytic relationship between redundancy accuracy are derived verified. suitable number stations suggested be 40 achieve counterbalance efficiency saturable accuracy. For PPP batch-estimated clock, impacts TDB clarified. experiments carried out investigate performance. causes a significant clock. impacted assimilation ability orbit error. convergence time after primarily affected respectively.

Efficient High-Rate Satellite Clock Estimation for PPP Ambiguity Resolution Using Carrier-Ranges
In order to catch up the short-term clock variation of GNSS satellites, clock corrections must be estimated and updated at a high-rate for Precise Point Positioning (PPP). This estimation is already very time-consuming for the GPS constellation only as a great number of ambiguities need to be simultaneously estimated. However, on the one hand better estimates are expected by including more stat...
متن کاملImpacts of Satellite Orbit and Clock on Real-Time GPS Point and Relative Positioning
Satellite orbit and clock corrections are always treated as known quantities in GPS positioning models. Therefore, any error in the satellite orbit and clock products will probably cause significant consequences for GPS positioning, especially for real-time applications. Currently three types of satellite products have been made available for real-time positioning, including the broadcast ephem...
متن کاملReal-Time PPP Based on the Coupling Estimation of Clock Bias and Orbit Error with Broadcast Ephemeris
Satellite orbit error and clock bias are the keys to precise point positioning (PPP). The traditional PPP algorithm requires precise satellite products based on worldwide permanent reference stations. Such an algorithm requires considerable work and hardly achieves real-time performance. However, real-time positioning service will be the dominant mode in the future. IGS is providing such an ope...
متن کاملEstimation and Analysis of Precipitable Water Vapor Using GPS Data and Satellite Altimeter
Determination of water vapor in the atmosphere plays an important role in forecasting weather conditions and precipitation studies. For this reason, it is very important to study the tropospheric delay, especially the wet component, which is due to the presence of water vapor in the atmosphere. In this paper, the amount of water vapor was estimated by altimeter satellite radiometer and GPS data...
