About this app

Connect to a high accuracy GPS or GNSS receiver, stream DGPS or RTK correction data to the receiver via NTRIP over the phone's Internet connection. Log NMEA position data from that receiver to a file on the SD card. Make NMEA position data from an external receiver available to other Android applications.

Note that this application requires the Bluetooth Serial Port Profile to connect to a GPS receiver. Bluetooth SPP is not included in all Android devices.

Permissions Needed:
INTERNET - Used for getting correction data from the Internet.
BLUETOOTH - Used for connecting to a Bluetooth device.
BLUETOOTH_ADMIN - Used for pairing with a Bluetooth device.
WRITE_EXTERNAL_STORAGE - Used for writing NMEA data to a text file on the SD card.
ACCESS_MOCK_LOCATION - Used for routing external position data to other applications.
ACCESS_FINE_LOCATION - May be used for sending location to NTRIP caster instead of using data from the external receiver or a manually entered lat/lon.
IN_APP_BILLING - Used for the subscription for the premium features.

Ratings and reviews

The application is turning off when phone is put to sleep. Even when app is minimized. It is giving me - Network Disabled massage. In such way it is preventing other tracking applications to keep tracks going on. I think this is major disadvantage and should be fixed. I tried all possible solutions about Power modes and Bluetooth but no luck. Seems it is app problem.

Top notch stable NTRIP Client. have used it for about a year now and its been great to me. One thing I'd like in the next update. When I was using older android devices I would have a nice little persistent notification in the top bar showing fix state. Green R for fix, red F for float and blue D for DGPS or an X if it wasnt connected. On my S8 on oreo I do not get these persistent notification in the top bar. I absolutely love them and want them to work. Audio notification works fine.

The interface is perfectly simple. Would give it 5 stars if it was able to stream all NMEA messages (not just GGA) so we can see other important details like satellite geometry, RMS, SNR, etc. in real-time. It does record all NMEA messages though, so we can check after afterwards.
