There are an increasing number of IoT applications, and projections show that global Low Power Wide Area (LPWA) connections will increase by almost one order of magnitude in the next five years. Terrestrial networks are continuously targeting evolutions of the IoT markets. For example, the latest release of 3GPP standards has introduced modifications to their standard (e.g. NB-IoT) to comply with…

GNSS is the only global, free, comprehensive technology providing absolute PNT data to users worldwide. Its limitations are known, including long life cycle and replenishment schedule, affecting their ability to adapt easily to short-term market needs and to some extent, resilience. Considering the above, alternative PNT methods and solutions have been developed or are being investigated,…

The need for high accuracy PNT in challenging environments has become obvious and, henceforth, mandatory for many applications. Currently, an accuracy target of 1 m in an urban environment seems a realistic achievement with multi-GNSS PPP or RTK capabilities. A significant R&D effort is ongoing to reach this target in operational products, using carrier phase positioning (PPP and RTK) and European…

In the last years, there has been fast progress in satellite on-board computing achieved by the satellite telecommunication industry. On-board processors are more performant, with less mass, volume and power consumption. As regards current and evolving space-based PNT data layer services (e.g. private or public GNSS data augmentations), they usually retransmit data computed on-ground via…

Until recently, RTK and PPP technologies have been developed for professional applications, the price not being affordable for mass-market users. Over the last couple of years, however, impressive breakthroughs have been witnessed for mass-market applications. While multi-band GNSS will provide an improved user experience in many consumer settings, the solution alone cannot deliver sufficiently…

The exploitation of GNSS time as a reference source for timing and synchronisation processes is becoming fundamental for critical infrastructures like telecommunication networks, energy distribution grids, financial markets, and commercial aviation systems and networks. In the case of commercial aviation, GNSS time is used for: Positioning and timing for on-board navigation…

Maritime transport is currently facing new challenges such as significant increases in transport volumes, more stringent environmental requirements and a shortage of seafarers in the future. One of the many new concepts having the potential to overcome these challenges is autonomous ship navigation. In particular, the concept is expected to allow for more efficient and competitive ship operations…
