Special Issue Information
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.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Remote Sensing is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
