With tens of thousands of LEO satellites launched or to be launched in the coming decades, the LEO augmentation in the ground-based Positioning, Navigation and Timing (PNT) service has become a hot topic in recent years. Compared with MEO or GEO satellites of different GNSSs, the LEO-augmented PNT service can benefit from the increased satellite numbers, the strengthened signal strength, and the rapid geometry change, which improves the estimation precision, enlarges the service area, and shortens of convergence time of, e.g., precise point positioning (PPP). In this Special Issue, we aim to study diverse components that contribute to the LEO-augmented PNT service, including (but not limited to) signal processing and analysis, sensor calibration/validation, and determination and prediction of the LEO satellite orbits and clocks. In addition, this Special Issue aims to explore the possible benefits of the PNT service and its integrity monitoring brought by the LEO mega-constellations, including strategy design, algorithm development, and data analysis based on simulations and experiments.
In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following:
- LEO POD and prediction;
- Integrated LEO-GNSS POD;
- LEO satellite clock analysis and prediction;
- LEO-augmented GNSS positioning and navigation;
- Frequency and time transfer under LEO augmentation;
- LEO signal processing and analysis;
- Integrity monitoring of LEO satellite orbits and clocks;
- Integrity monitoring of LEO-augmented ground-based positioning;
- Quality control of LEO signals;
- Constellation design of LEO satellites;
- Calibration/validation of spaceborne and terrestrial sensors related to LEO satellite signals.
We look forward to receiving your contributions.

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.
