mobileNtrip 3.0 for Bluetooth connection - NEW!

mobileNtrip for Bluetooth connection (like a mobileNtripPro for cable version) has a VRS (Virtual Reference Station) option which enables reading NMEA format data from GPS receiver with sending it to the Ntrip Caster before receiving correction data.

In most network solutions it is necessary to send the position of the Ntrip Client to the Ntrip Caster. That position could be used by the Ntrip Caster to provide a data stream for a Virtual Reference Station (VRS) or to determine the best data stream to broadcast.
mobileNtrip allows clients to send NMEA GGA strings after the HTTP request for a data stream.

You can see a simple VRS system at this schema.

mobileNtrip works fine with VRS Trimble and GNSMART GEO++ systems with iGate and GNCASTER correction data servers. It can be used also with single reference stations in BROADCAST mode.

A great advantage of this version is that you can use it with all available reference stations systems using Ntrip protocol to provide GNSS data!


In this version (3.0) we added possibility to set NMEA string manually! This is very valuable function for GPS receivers without NMEA send option in case of selected Mountpoint which requires sending NMEA to the Caster.

For making NMEA string you need to write Latitude, Longitude with proper Directions and Altitude.

Next, you can set NMEA string to be sent only one time to the Caster or to send it every time GPS receiver will release a new string.

Finally, you are able to control the size of correction data buffer which is send to GPS receiver via Bluetooth. This setting is needed when there is no EOL character inside data stream. The size depends of correction data type, so you should find optimal value for your Mountpoint. Default value is 128 bytes.


It is very ease to operate with connection with GPS over Bluetooth and the Caster. Two main operation screens allow you to control all needed parameters and data.

To operate with this version of mobileNtrip you need:
- GPS receiver - with differential correction data function and Bluetooth module
(separate COM-Bluetooth converted can be used also),
- GSM mobile phone - with sockets and Java Bluetooth API support.

List of supported devices for this version is available here.
