UWB-GNSS Precision Start-Gate Monitoring for Olympic-Class Windsurfing

Olympic-class windsurfing requires athletes to cross a start line at exactly the right moment — too early and they’re disqualified, too late and they lose seconds against the fleet. Current officiating relies on visual judgement and shore-based cameras with limited precision. This program develops marine buoy-deployed UWB + GNSS sensors that provide decimeter-class start-gate monitoring, giving coaches and officials objective timing for training and competition.

Why it matters. A new application domain for IPNL — marine-environment sports-tech — exercising the lab’s multi-sensor fusion expertise outside its established urban-PNT context. The buoy-deployed sensor design is the receiver-level contribution; the precision timing/ranging algorithms reuse the FGO methodology developed for urban GNSS.
