Bluetooth GNSS

About this app

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.

Ratings and reviews

Super impressed with this app. Easy configuration, it runs resident waiting for me to power up my Columbus P-70, connects instantly and gives me centimeter accuracy in my favorite map viewer (onx hunt). The hardest part was wrapping my mind around NTRIP RTK, then finding a local CORS service mount point. This app eases the latter by listing available mount points, which you can cross reference with a map given by your NTRIP provider. A+ work, thank you!

I've moved to a new phone running Android 15 and the app I used previously "Bluetooth GPS" doesn't install, so I gave this app a try. Setup was quick, it connected to my Garmin Glo and Android was receiving the Glo's location immediately. Tested with my Speedometer app (I was the author of the now retired 'DigiHUD Speedometer' app) and it works great. Only thing I miss is a real-time constellation view, but it's not a bigee. Thanks.

It appears that my Android smartphone communicates with my Garmin Glo2 just fine. What I can't get to work when I connect to the Glo2 with Bluetooth I don't see all the satellites it is connecting to with other GPS status apps like "GPS Test". How can I see exactly which satellites my Glo2 is connecting to? Also, Bluetooth GNSS is reporting "no data" for GLONASS satellites. I updated the Glo2 firmware and now the Glo2 is finding GLONASS satellites.

What’s new

- auto-reconnect params not show on reconnect fixed
- restore setmock use hdop*cep or ublox accuracy if present (used fixed 5m earlier as was trying for gmaps support)
- default dev CEP is 5 meters
