GNSS Position, Navigation, and Remote Sensing Based on Multiple Source Observation Fusing

Dear Colleagues,

The rapid development of Global Navigation Satellite Systems (GNSS) has brought forth new opportunities and challenges in providing precise positioning, navigation, and timing (PNT) services essential for various applications for Earth observing, geohazard monitoring and early warning, and civil applications. This Special Issue aims to (1) explore the intersection of GNSS with multi-source observations, encompassing diverse satellite systems (GPS, GLONASS, Galileo, BDS, etc.), Low Earth Orbiter (LEO) platforms, and other instruments such as inertial system, Lidar, visual sensors, to improve the accuracy, reliability, and robust of GNSS-based PNT services; and (2) discover the fusion of GNSS with other space-based Earth observing technologies such as satellite altimetry, GNSS Reflectometry, and InSAR, coupled with ground-based technologies such as radiosonde and ionosonde, to provide enhanced terrestrial and space weather monitoring data characterized by improved spatial and temporal resolutions.

Contributions to this Special Issue are invited to cover recent advances, challenges, and applications in GNSS technology, positioning algorithms, and remote sensing methodologies. We welcome both theoretical and applied research that explores the synergies between GNSS and other observational sources, fostering innovation in geoscience applications and high-precision positioning. Topics of interest include:

• Advanced GNSS positioning algorithms and methodologies.
• Integration of GNSS with other satellite-based observations for improved accuracy.
• Integrated processing of multi-GNSS and LEO observations.
• Applications of GNSS in remote sensing.
• Utilization of multi-source observations for enhanced terrestrial weather and space weather monitoring.
• Next-generation navigation technologies leveraging multi-source observations.
• Earthquake, tsunami, and volcano monitoring and early warning using real-time GNSS.
• GNSS Reflectometry.
• GNSS Signal Processing.

This Special Issue provides a platform for researchers to share their latest findings, methodologies, and insights, contributing to the collective knowledge in the field. We encourage submissions that bridge the gap between GNSS positioning, navigation, and remote sensing, showcasing the potential of multi-source observations to address contemporary challenges.

We look forward to your valuable contributions to this vibrant and interdisciplinary exploration of GNSS.

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 250 words) can be sent to the Editorial Office for assessment.

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.
