NTRIP Client by Messick's description

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.
