NTRIP Client by Messick's

Transports DGPS or RTK corrections to your GNSS or GPS receiver over the internet via the NTRIP Protocol. This app is designed for advanced users with a working knowledge of DGPS technologies and their application in precision farming.

This application requires the Bluetooth Serial Port Profile, which is not included in all Android devices.
For a Bluetooth to serial adapter we recommend the Parani-SD1000
Dashboard gauges require your monitor to output GPGGA and GPRMC strings back to your android device.
