Special Issue Information

Dear Colleagues,

Welcome to the second edition of the Special Issue. The last ten years have seen enormous technical progress in the field of indoor positioning and indoor navigation; yet, in contrast with well-established outdoor GNSS solutions, no technology exists that is cheap and accurate enough for the general market. The potential applications of indoor localization are all-encompassing, from home to wide public areas, from IoT and personal devices to surveillance and crowd behavior applications, and from casual use to mission-critical systems.

This Special Issue encourages authors, from academia and industry, to submit new research results about innovations for indoor positioning and navigation. The Special Issue topics include but are not limited to:

- Location-based services and applications;
- Benchmarking, assessment, evaluation, standards;
- User requirements;
- UI, indoor maps, and 3D building models;
- Human motion monitoring and modeling;
- Robotics and UAV;
- Indoor navigation and tracking methods;
- Self-contained sensors;
- Wearable and multisensor systems;
- Privacy and security for ILS;
- Standards and protocols for interoperability;
- Indoor maps

Wi-Fi round-trip timing (RTT) was applied to indoor positioning systems based on distance estimation. RTT has a higher reception instability than the received signal strength indicator (RSSI)-based fingerprint in non-line-of-sight (NLOS) environments with many obstacles, resulting in large positioning errors due to multipath fading. To solve these problems, in this paper, we propose high-precision RTT-based indoor positioning system using an RTT compensation distance network (RCDN) and a region proposal network (RPN). The proposed method consists of a CNN-based RCDN for improving the prediction accuracy and learning rate of the received distances and a recurrent neural network-based RPN for real-time positioning, implemented in an end-to-end manner. The proposed RCDN collects and corrects a stable and reliable distance prediction value from each RTT transmitter by applying a scanning step to increase the reception rate of the TOF-based RTT with unstable reception. In addition, the user location is derived using the fingerprint-based location determination method through the RPN in which division processing is applied to the distances of the RTT corrected in the RCDN using the characteristics of the fast-sampling period.
