GPS Synchronisation

GPS Time & Location Synchronisation

Gordon's Sun Clock can optionally use GPS to synchronise time and location. This is primarily relevant for devices without internet access and for applications that require precise local solar timing.

Note: GPS synchronisation is optional. The app works fully without it.

Why use GPS synchronisation?

For wall clocks without internet

Devices without network access can use GPS to synchronise the system clock. This keeps your Sun Clock accurate and fully functional even offline.

For Agnihotra practitioners

With "Auto location" enabled, GPS determines your exact coordinates to calculate precise sunrise and sunset times for your specific location.

At the same time, your device's system clock is synchronised with the atomic clock network via GPS. I've experienced deviations of up to 2 seconds between device time and atomic-clock time, which GPS sync automatically corrects.

The "+" symbol next to the Agnihotra times confirms that both the location and time sync are less than three minutes old.

How to enable GPS synchronisation

1. Open Settings in Sun Clock
2. Enable "Location/Auto-locate"
3. Grant location permissions when prompted
4. Enable "Modes/Agnihotra (GPS)"
5. The app will now use GPS for time and location synchronisation

Privacy & Data

GPS synchronisation happens entirely on your device. No location data is transmitted or stored externally. Sun Clock collects no data.
