GPS DOP and millimetre error - Edinburgh, Scotland
All data from Raspberry Pi 4 (2 GB RasPi-25) using a Uputronics GPS/RTC module with an outdoor antenna.
The module (a u-blox MAX-M8Q-0-10) is set to use all three GNSS constellations. Location: 55.9° N, 3.2° W
Values are those reported by the u-blox firmware.
