The PPP–RTK method, which combines the concepts of Precise of Point Positioning (PPP)
and Real-Time Kinematic (RTK), is proposed to provide a centimeter-accuracy positioning …

Abstract The Galileo High Accuracy Service (HAS) is a GNSS augmentation that provides
precise satellite corrections to users worldwide for free directly through Galileo's E6 signal …

Integer ambiguity fixing can significantly shorten the initialization time and improve the
accuracy of precise point positioning (PPP), but it still takes approximate 15 min of time to …

Precise point positioning (PPP) can be significantly improved with the multi-multi-GNSS
constellation, but it still takes more than 10 min to obtain positioning results at centimeter …

This thesis deals about geodetic applications of the Global Positioning System (GPS), in
which the position of the GPS receiver must be determined with cmprecision. This requires a …

The past few years have seen substantial growth in multiple-reference-station networks
which are used to overcome the limitations of standard real-time kinematic (RTK) systems …

The global navigation satellite system's signals are frequently obstructed in complex
environments, and the carrier phase is prone to experiencing large cycle slips; hence, phase …

Single receiver positioning has been widely used as a standard and standalone positioning
technique for about 25 years. To detect the slowly growing faults caused by satellite and …

To perform the most precise relative positioning using GPS, it is necessary to resolve the
carrier-phase integer cycle ambiguities. This process becomes increasingly difficult as the …

In this study, a tropospheric delay model that integrates tropospheric delays derived from the
European Centre for Medium-Range Weather Forecasts fifth-generation global atmospheric …
