How do you tell folks what’s going on from a plane w/no engine?!
summary
Gliders travel hundreds of miles on rising air and FLARM beacons provide local positions; a ground system links FLARM/OGN feeds to the web. The project implements an OGN WebGateway written in Rust using actix with an Ember frontend, moves history from Postgres/TimescaleDB (20 million rows, 20s queries) to Redis time buckets (queries ~20 milliseconds), supports 30–40 mile ground reception, and produces live scoring that predicts final speeds to two decimal places.
