BDS/GNSS for Earth Observation (Third Edition)

Dear Colleagues,

Over the past 20 years, GNSS has become a leading technology in Earth observation with strong applications, not only in conventional positioning, navigation and timing techniques, but also in integrated remote sensing solutions, such as typhoon monitoring, river water level changes, geological hazard warnings, low-altitude UAV navigation, and so on, due to its high performance, low cost, and availability at all times and in all weather conditions. After the excellent results of the first edition of the Special Issue “BDS/GNSS for Earth Observation” (with 34 papers submitted, 17 of which were accepted and published, constituting a 50% acceptance rate), and of the second edition (with 28 papers submitted, 13 of which were accepted and published, constituting a 46% acceptance rate), a new edition is herein proposed.

In this Special Issue, recent progress in the application of multi-GNSS in Earth observation are welcome for presentation and review, including BDS/GNSS methods for Earth observation, GNSS ionospheric modelling and space weather monitoring, GNSS navigation and positioning performance (e.g., GNSS-PPP and GNSS-NRTK), GNSS reflectometry, and GNSS meteorology and its applications. The aim of this Special Issue is to present the latest state-of-the-art findings, including, but not limited to, the following topics:

• Theories and methods of multi-GNSS NRTK, PPP and PPP-RTK;
• Analyzing errors, systematic effects and noise in GNSS solutions;
• Troposphere and ionosphere observations, modeling, and assimilation from ground and space receivers;
• GNSS-reflected signals and applications;
• Geohazard observation and warning from GNSS;
• Surface-loading GNSS observations relating to the atmosphere, hydrological issues and loading issues.

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.
