Ultrasonic Positioning and Navigation

Dear Colleagues,

The development of emerging technologies enabling Ultrasonic Positioning and Navigation paves the way to an exciting broad range of applications.

Accurate information and real-time positioning of users, devices, and robots foster the development of new applications for augmented and mixed reality, human–machine, and home automation gestural interfaces, and navigation in airport, hospital, and shopping centers.

Further fields of application include medicine, such as monitoring elderly people’s movements or rehabilitative exercises; logistics, such as the positioning of goods in warehouses; and sport, such as monitoring body and limb position during training exercises and in game consoles.

Particular interest is dedicated to those environments in which the availability of global satellite navigation systems is denied or challenging or the positioning accuracy is insufficient, such as indoors, in the industrial, commercial, and consumer sectors. In such environments, ultrasound positioning techniques have emerged as the most promising in terms of accuracy and reliability.

This Special Issue aims to gather contributions on sensors for positioning exploiting ultrasound technology. Furthermore, the scope of this Special Issue covers also sensing and processing methods applied to the navigation problem. These include robust numerical methods, optimization strategies, tracking algorithms, machine learning, and performance characterization and validation methods.

At present, the research effort needs to be directed to new algorithms, architectures, and sensor technologies to improve coverage, power consumption, size, and to increase spatial and temporal resolution of ultrasonic positioning and navigation systems, taking into account the physical and economic constraints of the various applications.

In this framework, it is our pleasure to edit this Special Issue on “Ultrasonic Positioning and Navigation". Original contributions focused on systems and technologies to enable the applications listed above are welcome.

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.
