Special Issue on: Ubiquitous Positioning, Navigation and Timing for Location Based Services

Satellite Navigation welcomes submissions to the thematic series on 'Ubiquitous Positioning, Navigation and Timing for Location Based Services':

Position, Navigation, and Timing (PNT) are critical for location-based applications. Today Global Navigation Satellite Systems (GNSS) such as the United States’ GPS, Russia’s GLONASS, China’s BeiDou, Europe’s GALILEO and their augmentations, are critical infrastructure fueling aspects of the new information/data economy. GNSS works well in environments where satellites have both good visibility (or line-of-sight) and geometric spread around the point of interest. In other (e.g. built) environments, GNSS signals can be significantly attenuated and even blocked. In order to ensure ubiquity of PNT, at the levels of performance required to support a wide variety of location based services including mission critical applications, researchers are exploring other ways to be used together with GNSS and/or on their own by (i) developing other sensors and systems, (ii) exploiting opportunistic signals/sensors/systems/geospatial data, (iii) developing mathematical models for sensor/data fusion, (iv) developing error modelling and filtering techniques, (v) exploiting advanced analytics including artificial intelligence and machine learning for measurement error characterization, and (vi) developing PNT quality and integrity monitoring techniques and models. Although it is acknowledged that PNT is critical to location-based services, not much specific attention is paid to the research required to quantifying the level of resilience required in the provision of PNT services and the corresponding technologies.
The aim of this Special Issue is to bring together the relevant researchers to begin to address to this important issue. It seeks to consolidate the research already undertaken and to chart the future research directions. It is within this context that we invite you to contribute to the thematic series on ‘Ubiquitous Positioning, Navigation and Timing for Location Based Services’. The topics of interests include, but are not limited to: 
1)       Receiver/sensor/antenna design technologies 
2)       Multi-source cooperative positioning methods in complex environments 
3)       Measurements/observables processing models (including error mitigation) 
4)       System/sensor/spatial data integration or data fusion, and applications, with a particular focus on very high performance as measured in terms of the required navigation performance parameters of accuracy, integrity, continuity and availability
5)       Errors and their modelling 
6)       Interference (jamming, meaconing and spoofing) and integrity/quality monitoring
7)       Advanced analytics (e.g. AI) based applications 
8)       Edge Computing Assisted High Performance Localization 
9)       Indoor Localization and Navigation Systems
10)     Timing Systems 
11)     Achieving high PNT resilience
