High-Precision GPS Positioning for Spring Developers
summary
Shows how to get 1–2 centimeter RTK accuracy using a cheap base‑station+rover setup (Arduino-powered, u-blox ZDF9P modules) versus phone GNSS (examples: ~9 m single‑freq, ~3.8 m dual‑freq, 0.5 m with external receiver). Builds a working pipeline: NMEA over Bluetooth/serial into a Spring Boot app, parsed with Spring Integration, exposed via Micrometer → Prometheus → Grafana, and persisted to PostGIS for visualization with Leaflet.js; demos and Docker compose artifacts are provided.
