Editorial interest 84/100 Selection signal · not a rating of the site

Raysilience presents MONDRIAN, a visual positioning system for autonomous aerial platforms operating in GNSS-denied or GNSS-degraded environments.

Landing page captured for the 2026-08-20 issue.

Why it surfaced

The system combines live camera imagery, inertial data, and preloaded Earth-observation maps to produce an onboard position fix without a satellite signal. Its unusually concrete technical pitch includes a claimed accuracy of under 3 metres CEP, a 60 Hz update rate, and a proof of concept with Leonardo alongside incubation at ESA BIC Lazio—an interesting glimpse of how autonomy is being engineered for a world of jamming and spoofing.
