Factor graph optimization is gaining attention from the community as is outperforming traditional positioning algorithms. Factor graph optimization may be used to replace the traditional Weighted Least Square (WLS) or Kalman Filter (KF)-based solutions, both in stand-alone and hybrid positioning solutions in combination with sensors. Thus, its application may be of interest for the derivation of…

Positioning, Navigation, and Timing are essential for modern infrastructure, including transportation, agriculture, and space applications. Thanks to developments in GNSS, particularly the European Galileo system, navigation devices are now ubiquitous, with smartphones serving as multi-sensor platforms. However, high-quality positioning solutions are not always guaranteed due to weak GNSS signals,…

MEDEA is an EGNSS/INMARSAT Rx multiband digital array antenna that covers the two bandwidths from 1150 up to 1290 MHz and from 1539 to 1610 MHz. MEDEA can be considered a sort of “applique equipment” for any standard GNSS receivers because of, in addition to gather RF signal from the outside space, it embeds a few features to improve the integrity of the receiver operations to which it is…

Reliable and uninterrupted access to satellite navigation data is nowadays a key element for various branches of economy, security and safety. At the same time, GNSS systems are not 100% reliable and the issue of interference (both unintentional and intentional) affecting their operation is becoming more and more significant – especially in current geo-political situation. That is why a constant…

Following publication of the UK's first PNT Policy Framework to ensure resilience in its PNT infrastructure, NLAI will provide strategic support to the UKSA and the National PNT Office by updating key policy input sources to the SOTA (State-Of-The-Art) assessment, used to support business cases, decisions, planning, and preparedness actions. SPARK will undertake a review of the current PNT…

The INSPIRE project aims to design, develop, and validate a novel GNSS-based positioning architecture tailored for challenging environments such as urban canyons and deep-urban areas. The project leverages meta-signal processing, peer-to-peer ranging, and hybrid positioning to improve accuracy, robustness, and availability of GNSS-based solutions in scenarios where traditional positioning systems…

ODYSSEY (Orbits-as-a-Service for Satellite Signals of Opportunity) is funded through Element 2 of the ESA NAVISP programme and is being carried out by GMV-UK. It will develop a precise orbit determination centre for communications satellite constellations. This will be used to provide a new commercial service generating precise orbits for different satellite constellations whose signals can be…
