New NAVISP INSPIRe Project Targets Integrity

The European Space Agency’s NAVISP program continues to churn out on-point, PNT-related research at a time of increasing interest in the resilience, or lack thereof, of GNSS-based solutions. Among the latest NAVISP-funded projects to achieve completion is INSPIRe (Integrated Navigation System-of-Systems PNT Integrity for Resilience), which investigated a number of approaches for providing integrity of GNSS-derived PNT for maritime users.

Using LEO Signals of Opportunity for PNT

A new paper (June 2024) published in Navigation, the Journal of the Institute of Navigation, by Arial Baron, Pini Gurfil and Hector Rotstein of Technion-Israel Institute of Technology, describes a useful approach for navigation based on low Earth orbit (LEO) satellite signals of opportunity (SoOps), using carrier Doppler-shift observables.
