062 - Lunar surface PNT Beacon demonstrator
In line with Phase 3 of the reference Roadmap for Lunar PNT service provision (ESA/PB-NAV(2020)9) and in complement to the development of a LCNS navigation payload Elegant Breadboard proposed above as activity NAVISP-El1-061, there is technical consensus on the importance to implement pre-developments of the most critical associated PNT technologies.
A PNT beacon transmitter/reference station…
060 - Novel privacy preserving PNT processing techniques
Up to now, cloud-based processing of positioning data (e.g. samples, raw measurements, anonymised Position, Velocity and Time) has always been susceptible to data breaches and raised concerns about privacy protection. Location-based services can fail in their path to wide-spread adoption, because they are perceived as invasive by the users and fail to properly address their risks. Similar issues…
059 - Application of photonics technology for PNT user equipment
The demand for seamless positioning of IoT devices both outdoors and indoors is an important requirement for many logistic applications relevant to the digital transformation of industry. This is becoming more relevant as the degree of automation in industrial operations increases, together with the need of permanently tracking the location of inputs from suppliers, to be able to forecast…
058 - Demonstration of GNSS position bounding using satellite uplinks
The number of miniaturized devices with satellite connectivity (e.g. asset trackers) is quickly growing, and with this, the need arises to provide reliable positioning information to those resource-limited devices. This is particularly relevant in growing asset tracking and user-charging use cases, in many sectors such as in railway (wagons and containers tracking), maritime (VMS, container…
057 - Development of advanced VDES-R user technologies for alternative PNT
VDES (VHF Data Exchange System) aims at digitalising maritime communications and enable the introduction of new capabilities for a variety of maritime use cases, such as AIS and Search and Rescue. It is also being considered to support alternative PNT with a dedicated ranging capability, the so-called R-mode or VDES-R, which is currently being investigated. The initiative is supported by IALA…
055 - Attitude control of autonomous ships navigating in ports
One of the many new emerging concepts having the potential to address present and future maritime challenges is autonomous ship navigation. In particular, the concept is expected to allow for more efficient and competitive ship operations while reducing, at the same time, vessels’ environmental impact.
Several activities have been initiated in the recent years with the aim to jumpstart the…
054 - Monitoring timing signals from space. A novel approach for a worldwide robust time and synchronisation capability
Many systems (including critical infrastructure) rely on GNSS receivers for synchronization purposes nowadays, for instance telecom networks, power grids and financial markets. Due to the vulnerability of GNSS to interference and spoofing, there is a growing need on alternative (non-GNSS-dependent) timing services, as shown by several investigations and initiatives on this topic (e.g. European…
052 - Robust navigation of airborne autonomous systems with carrier phase of ARNS signals
As the Unmanned Aerial Vehicle (UAV) regulatory framework continues to evolve towards autonomous flight and operations beyond visual line-of-sight (BVLOS), it drives the need for reliable navigation services to complement or act as a back-up to existing ones. Trusted PNT solutions have to be developed to help tackle the many challenges that a congested airspace brings such as the safety of…
