4. Using FieldGenius with Lefebure NTRIP Caster The NTRIP protocol can offer many configurations for servicing GNSS rover instruments with access to multiple GNSS reference instruments The following steps provide a simple example of configuring a single GNSS reference instrument to supply a correction stream CMR RTCM to one or more GNSS rover instruments The diagram below illustrates the relationship between the NTRIP Server the NTRIP Caster and the NTRIP Clients NTRIP Server GNSS Reference NTRIP Client GNSS Rover NTRIP Caster Lefebure program NTRIP Client GNSS Rover on computer Internet through GSM GPRS NTRIP Client GNSS Rover Step A NTRIP Caster Setup The Lefebure NTRIP Caster application is a third party NTRIP Caster which manages multiple connections from NTRIP Servers GNSS references and NTRIP Clients GNSS rovers Download the application from the link http lefebure com software ntripcaster NTRIPCaster exe and run the executable NTRIPCaster exe on a Windows based computer with a direct internet accessible computer and IP address Please make a note of the computer s IP address because this will be used for connection by the NTRIP Servers and NTRIP Clients The NTRIP Caster is hard coded to use port 5000 for TCP IP connection Upon initial running of the NTRIP Caster all parameters are set up by default and the application is ready for use The user can continue onto step 2 otherwise co
