On planet.molssoft.lv, nginx serves this page from public/ over HTTPS and proxies /socket.io to the Geo Node process on port 3000 (same origin in the browser).

Uses the browser Geolocation API. The page requests your position immediately, then again every 5 seconds. Works best over HTTPS or on localhost. When the screen sleeps, timers and GPS are usually paused or throttled; we try to keep the screen on while this tab is visible.
