Live GPS position readout — accuracy, altitude, speed, heading, and update rate. Logs a position trail to reveal drift over time.
Requests the highest-accuracy GPS fix available. On mobile this uses the hardware GPS chip; on desktop it falls back to Wi-Fi triangulation, which is far less accurate.
The dot is the reported position; the circle is the accuracy radius. A smaller circle means higher confidence. On hardware GPS outdoors this often reaches 3–5 m.
Circle scales with reported accuracy — watch it shrink as the GPS warms up.
Each GPS update is logged below. Standing still, positions should cluster within the accuracy radius. Large scatter while stationary indicates poor signal or multipath error.
