Dear Colleagues,

Precise Point Positioning (PPP) based on Global Navigation Satellite Systems (GNSS) provides highly accurate positions, and its adoption is rapidly growing in several applications.

The trend of autonomous driving in transportation (automotive, UAVs, maritime, rail, and personal transportation) has increased the need for positioning with centimeter-level accuracy, which cannot be reached with standard GNSS solutions. The modernization of GNSS, the use of multiple constellations, and multiple frequencies reduced the time required by PPP techniques to converge to the desired accuracy level. Recently, the European Commission started the provision of the Galileo High Accuracy Service, which will include free PPP corrections worldwide and further promote the adoption of PPP in mass-market and non-professional sectors.

In this context, challenges such as the reliability and integrity of GNSS PPP need to be addressed and solved. These aspects are crucial, especially in safety-critical applications, which are affected by degradation due to local threats, multipath, ionospheric anomalies, no line-of-sight signals, signal masking, and inaccurate error models. Research topics of interest include but are not limited to advanced PPP techniques, advanced integer ambiguity resolution, advanced receiver integrity monitoring algorithm, advanced fault detection and exclusions, ranging error bounding and time correlation models, the integration of local sensors, the integration of signals from Low-Earth-Orbit (LEO) satellites, external services based on high-resolution maps, error model characterization, and the application of machine learning techniques.

This Special Edition aims to discuss the latest research on PPP innovative solutions and develop new ideas and research directions. Articles will foster and contribute to the research on this new GNSS frontier.

Abstract

Although deformations are mostly insignificant, they can be catastrophic when accumulated to certain amounts. Precise point positioning (PPP) can work with one receiver, preventing problems caused by the base station constrain upon employment of current methods such as real-time kinematics (RTK). However, current methods employing PPP focus on high-frequency monitoring such as earthquake or geological calamity monitoring, and these methods are not suitable for structures. Thus, this study proposes a new method for the deformation monitoring of structures via PPP. First, we obtained the coordinate sequence of structures via static PPP when setting the interval. Then, we transformed the coordinates to the same coordinate system with the same basis. Finally, we decomposed the sequences via empirical mode decomposition (EMD) to obtain a low-frequency part, which is the deformation of the target structure. The result of the monitoring experimentation on IGS stations shows that the monitoring index,

S^{d}

, of the sequence under different intervals using this method could be 1–2 mm on average in the directions of E, N, and U, which is much better than the original monitoring sequence. Alongside that, it prevented a fall in accuracy when the interval decreased. Therefore, all results proved the feasibility and validity of the method. Full article
