abdelachbani/Sensatex ? reverse-engineered prompt

Build me an off grid GPS rescue navigation device for an ESP32 S3 that talks to a Quectel LC29H GNSS receiver over UART and creates its own Wi Fi network so a phone can connect with no internet. I want a simple browser based app that shows the current position, speed, time, satellite count, and heading, plus a compass or arrow that points toward a target location and shows distance and bearing.

Also make the onboard TFT display show the same kind of live navigation info, with a clear arrow and readable telemetry. Let me enter a destination in different coordinate formats like decimal degrees, DMS, and UTM, and keep the saved locations in the browser so they stay after reloads. If anything needs current library or docs details, look them up online. Keep it reliable, responsive, and usable in an emergency setting.
