Advanced Technologies for Position and Navigation under GNSS Signal Challenging or Denied Environments II

Dear Colleagues,

Currently, with the popularity of smart devices, assured position navigation and time (PNT) is critical for these devices and some fundamental infrastructures, e.g., the power grid. Global navigation satellite systems (GNSSs) are dominant in providing PNT information due to their coverage and high accuracy. However, their signals are weak, and they are vulnerable; multipath and non-line-of-sight (NLOS) signals are the major errors that occur with regard to GNSSs in applications in urban areas. Advanced signal processing methods are expected to improve their resilience and assurance. In addition, GNSSs are fragile to interference and spoofing, which should be emphasized for unmanned systems and smart devices.

Apart from improving GNSS resilience in signal-challenging environments, PNT without a GNSS is critical for many applications—i.e., indoors, tunnels, underground, etc. Advanced technologies on high-accuracy inertial sensors and timing devices—i.e., MEMS gyroscope, atomic interferometer gyroscope, nuclear magnetic resonance gyroscope, chip scale atomic clock, etc.—are key to supporting PNT in GNSS-denied environments. Multisensor integration is also a prospective solution. The previous Special Issue “Advanced Technologies for Position and Navigation under GNSS Signal Challenging or Denied Environments” was a great success. This second volume aims to provide a platform for researchers to publish innovative work on advanced technologies for position and navigation under GNSS signal-challenging or denied environments. Specifically, we invite contributions concerning the following topics:

1. GNSS multipath and NLOS identification, mitigation or correction;
2. Weak GNSS signal tracking and position determination;
3. GNSS interference and spoofing detection;
4. LiDAR/Visual SLAM;
5. MEMS inertial measurement unit;
6. Atomic Interferometer Gyroscope and Accelerometer;
7. Indoor position;
8. Multi-sensor integration and fusion;
9. Micro-Technology for Positioning, Navigation, and Timing.
10. Control theory and cooperative navigation.

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-blind 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.
