We build Celestinha: a star-navigation module that keeps uncrewed boats and drones on course over the ocean when GNSS is jammed or spoofed.

The investor deck, the pitch from the hackathon final, the documents for engineers.
Thirteen slides for investors: GNSS jamming at sea, how Celestinha navigates by the stars, the evidence, the simulator and the dashboard, competition, market, traction, roadmap, the €250k pre-seed ask and the team.
The pitch as presented at the final of the EUDIS Defence Hackathon at Startup Leiria, in the GNSS-Denied Navigation challenge: sixteen slides with the live star demo and the simulator video.
The simulator, the navigation stack, the module's software and the decisions behind them live in the project repository on GitHub. GitHub asks you to sign in, and only engineers with access can open them.

A Mavic-class reconnaissance drone for Ukrainian units: it keeps flying under electronic warfare, reports straight into Ukrainian C2 and is repaired in the field.
Open SchwanThe original Luftschar project: a bolt-on module that turns off-the-shelf FPV drones into coordinated swarms, using UWB relative positioning instead of GNSS.
Open StarA long-range FPV drone from DroneAid Collective. Specifications will be published once they are confirmed.
Open VogelAn unmanned ground vehicle (UGV). Its scope and specifications are still being defined.
Open OstrichAn autonomous interceptor drone with a hand launcher, from DroneAid Collective. It builds on the anti-Shahed interceptor work; the design is still being defined.
