GNSS Technology Advancements and Contemporary Applications in Geosciences

Dear Colleagues,

Global positioning systems (GPSs) have become indispensable tools across various scientific disciplines, particularly within the realms of remote sensing and geographical information systems (GISs). In recent years, GPS technology has evolved significantly and now plays a crucial role in a broad spectrum of environmental and geospatial studies. A subset of GPS technology, global navigation satellite systems (GNSSs), has emerged as a powerful means for conducting the remote sensing of the Earth's surface. By analyzing signals transmitted by GNSS satellites after they have been reflected off the Earth's surface, researchers can extract valuable data about surface characteristics and land composition. As a result, GPS/GNSS technology is increasingly utilized in the geosciences, offering new insights into the Earth's surface processes and contributing to a wide range of scientific and practical applications. The growing demand for GPS equipment and services, driven by both commercial and research needs, underscores the expanding scope and significance of this technology. The ability to remotely monitor and analyze the Earth's surface using GNSS signals opens up new possibilities for understanding environmental changes, managing natural resources, and addressing global challenges such as climate change and natural disasters. As the capabilities of GPS/GNSS technology continue to advance, its role in geoscientific research and practical applications is expected to grow, making it a critical area of study in the field of remote sensing and GISs.

The aim of the present Special Issue is to foster the advances in GPS/GNSS technology for a range of practical applications and research investigations in the field of geosciences. We particularly encourage both theoretical and applied research contributions furthering the knowledge on the use of this technology in all disciplines linked to geosciences. Such contributions can be focusing on various aspects, including, but not limited to, the following: the satellites; receivers; positioning algorithms; geolocation services, UAVs, important contemporary applications; and software tools development for data collection and processing.

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-anonymized 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.
