Real-time Clock and Orbit Corrections for Improved Point Positioning via NTRIP

Popis výsledku v původním jazyce

In this paper we report on the current status of NTRIP based GNSS stream collection and dissemination. We then describe the utilization of such data streams for the real-time estimation of accurate GNSS satellite clock corrections. The GNSS network processing software RTNet is used to estimate the clocks using predicted ultra-rapid IGS orbits. As a part of upcoming EUREF and the IGS test and evaluation efforts, the clock corrections are distributed via NTRIP to stationary or mobile users for improved Point Positioning performance. The quality of our clock corrections depends on the available real-time GNSS network. Thanks to the high number of NTRIP stations in the European area, corrections there are of the highest quality. We discuss the present status of the real-time clock and orbit determination and the achievable Precise Point Positioning (PPP) accuracy in different regions of the world. We also investigate whether the use of predicted IGS orbits is a limitation that necessitates
