It is long debated whether a relation exists between the tidal stress produced by the Moon and the Sun on the Earth crust and the occurrence of difference geologic events, in particular large earthquakes and volcanic eruptions. Clear evidence for this relation has been elusive for a long time. However, the analysis of more complete global earthquake catalogues has shown that a significant…

Quantum metrology techniques show great potential to enhance both precision and security of existing PNT techniques. It has been shown that, by probing physical quantities using quantum states of light and/or matter, one can achieve a precision beyond the theoretical limit set by classical mechanics. This effect has been demonstrated in a variety of contexts and is particularly useful in optical…

A great number of civilian and military applications relies on GNSS for PNT, however its availability could be put at risk by threats such as local interference, amongst others.  GNSS spectrum monitoring is essential for: detecting, characterising and localising interference sources, which could endanger the adequate reception and processing of GNSS signals;  initiating a justified…

GNSS simulations are an important toolset supporting system engineering trade-offs and decisions. They are used to display and monitor key system performance indicators as well as study system behaviour, both through synthetic scenarios and real data replay. Industry and ESA currently use different tools to simulate GNSS systems, however often constrained to undertake only one of two different…

Envisage Space has developed analytical software which we call RelyMap, which is designed to analyse wide areas (pan-city/region) of a complex urban environment and identify areas where GNSS signal provision is either impacted or blocked due to anomalies such as building shadowing etc.RelyMap Enhance builds upon this technology and understanding to enable improved location accuracy for GNSS…
