Bluetooth GNSS vs HailTrace Usage & Stats

Use accurate satellite positioning from powerful Connect to external Bluetooth GNSS (GPS/Galileo/GLONASS/BeiDou) receivers for better location accuracy with your Maps and Navigation apps that support the default Android Developer Option's 'mock location' feature location source. Supports Android 14 (tested on Samsung S24). 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.
