Special Issue Information

Dear Colleagues,

In modern communications, the software-defined radio (SDR) provides a well-known approach that allows the implementation of receivers with a high flexibility level. Global navigation satellite system (GNSS) receivers make no exception to this fact, and, in recent years, several examples of software (SW) GNSS receivers have been published in the literature. The advantage is two-fold: not only can the GNSS SDR receiver be easily updated during its operational life, but it is an outstanding tool for prototyping innovative algorithms. In the last decade, considerable effort has been devoted by the GNSS scientific community to SDR developments and standardization, which has resulted in numerous open-source projects.

This Special Issue aims to collect the most recent GNSS SDR developments, including the implementation and prototyping of new digital architectures for GNSS receivers on different platforms, e.g., standard-PC (general-purpose processors), single board computers (SBCs), embedded boards, graphics processing units (GPUs), smartphones; GNSS receivers, including those with real-time capabilities, research tools, and snapshot receivers; and data collection systems, e.g., SDR GNSS front-ends (FEs). Special attention should be given to implementation choices and details, optimizations for real-time processing, computational burden analysis, and performance evaluation. All applications will be of interest.

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. Sensors 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 2600 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.

In this study, a low-cost, software-defined Global Positioning System (GPS) and Satellite-Based Augmentation System (SBAS) Reflectometry (GPS&SBAS-R) system has been built and proposed to measure ocean-surface wave parameters on board the research vessel New Ocean Researcher 1 (R/V NOR-1) of Taiwan. A power-law, ocean-wave spectrum model has been used and applied with the Small Perturbation Method approach to solve the electromagnetic wave scattering problem from rough ocean surface, and compared with experimental seaborne GPS&SBAS-R observations. Meanwhile, the intensity scintillations of high-sampling GPS&SBAS-R signal acquisition data are thought to be caused by the moving of rough surfaces of the targeted ocean. We found that each derived scintillation power spectrum is a Fresnel-filtering result on ocean-surface elevation fluctuations and depends on the First Fresnel Zone (FFZ) distance and the ocean-surface wave velocity. The determined ocean-surface wave speeds have been compared and validated against nearby buoy measurements. Full article
