Investigate GPS issues & OPi power requirements
# Description
Context: https://gitlab.com/whitebox-aero/whitebox/-/work_items/375#note_2867134617
During recent tests, the GPS module occasionally failed to acquire a fix. This seemed to improve when using a larger battery capable of delivering 20W+, suggesting that insufficient power may be affecting GPS performance. The Orange Pi appears even more sensitive to power availability, so detecting and handling low-power conditions may be necessary.
Additionally, after leaving Whitebox running inside the aircraft, the app initially showed “disconnected” from GPS/traffic even though Stratux had a GPS fix (but no traffic). After some unknown action, Whitebox eventually displayed the correct GPS location again.
# Scope
- Investigate intermittent GPS acquisition failures and identify underlying causes.
- Evaluate the impact of insufficient power delivery (especially below ~20W) on the GPS module and Orange Pi performance.
- ~Add UI behaviour to display a clear “Acquiring GPS…” status with relevant details while waiting for a fix, following existing design specifications.~ **Moved to #541**
- ~Implement automatic zoom-in to the current location once a GPS fix is obtained, if the map is still at the worldview zoom.~ **Moved to #515**
