This work demonstrates that precise point positioning (PPP) can be used not only for
positioning, but for a variety of other tasks, such as signal analysis. The fact that the …

Highly accurate tropospheric delay information is essential for global navigation satellite
system (GNSS) data processing. However, the current models still have limitations such as a …

We develop a new integrated navigation system, which integrates GPS precise point
positioning (PPP) with low-cost micro-electro-mechanical sensors (MEMS) inertial system …

Accurate modeling of zenith tropospheric delay (ZTD) is beneficial for high-precision
navigation and positioning. Many models with good performance have been developed for …

Sensing of precipitable water vapor (PWV) using the Global Positioning System (GPS) has
been intensively investigated in the past 2 decades. However, it still remains a challenging …

Reanalysis products have been applied to calculate the tropospheric delay for Global
Navigation Satellite System (GNSS) positioning purposes widely. It is necessary to obtain …

The recent development of the Galileo space segment and the accompanying support of the
International GNSS Service (IGS) allows for worldwide Galileo-only positioning. In this study …

Precise modeling of tropospheric delay and weighted mean temperature (Tm) is critical for
Global Navigation Satellite System (GNSS) positioning and meteorology. However, the …

This chapter is a primer on global navigation satellite systems (GNSS s). It assumes no prior
knowledge of the systems or how they work. All of the key concepts of satellite-based …

Tropospheric delay is one of the main sources of measurement error in global navigation
satellite systems. It is usually compensated by using an empirical correction model. In this …
