GNSS and Integrated Navigation and Positioning

Dear Colleagues,

The term integrated navigation and positioning refers to the process of combining measurements from multiple sensors to determine the precise location and velocity of a moving object. This approach integrates measurements from different sources such as GNSS, inertial sensors (accelerometers and gyroscopes), and other sensors such as magnetometers, barometers, LIDARs, and cameras. By combining the measurements from these different sensors, integrated navigation and positioning systems can provide more accurate and reliable location and velocity information than GNSS alone. Integrated navigation and positioning systems are used in a wide range of applications, including aviation, maritime, land transportation, and surveying.

By combining data from multiple sensors, sensor fusion systems can overcome the limitations and uncertainties that may arise from the individual sensors' characteristics. The primary goal of sensor fusion is to extract useful information from multiple sources and obtain a more reliable and accurate understanding of the system or environment being observed. Sensor fusion is widely used in various applications, including robotics, autonomous vehicles, augmented reality, and virtual reality.

Cooperative positioning plays a further important role. In this technique, devices exchange information among themselves to obtain more accurate and robust location estimates. In addition to the use of fixed reference points, cooperative positioning can also be achieved using other devices, such as smartphones, that exchange information about their positions and environmental features, such as Wi-Fi signals, to improve location accuracy. The technique enables more accurate and robust location estimates than traditional positioning techniques.

This Special Issue, therefore, aims to put together original research and review articles on recent advances, technologies, solutions, applications, and new challenges in the field of GNSS and integrated navigation and positioning.

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. 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.
