Use accurate satellite positioning from powerful external Bluetooth GPS/Galileo/GLONASS/BeiDou receivers for better location accuracy with your favorite Maps and Navigation apps via Android Developer Option's 'mock location' feature.

Supports Android 12 (tested on Google Pixel 6).

Tested Bluetooth GPS/GNSS devices:
- Bad Elf GPS PRO+ (thanks to Bad Elf for providing test devices)
- Bad Elf Flex (thanks to Bad Elf for providing test devices)
- u-blox M8030
- ArduSimple u-blox F9 (including RTK/NTRIP)

Supports overlay of NTRIP server data streams for professional RTK positioning (centimeter-level accuracy - depends on device) if your Bluetooth GNSS/GPS device supports RTK.

For u-blox based devices this app also supports showing 'Accuracy' estimates from the U-Blox 'PUBX' accuracy messages instead of the commonly used 'HDOP x CEP' method. This PUBX accuracy reading exactly matches as is the same source of the 'Accuracy' as shown in U-Center PC tool when connected directly via USB.
