This brief document guides you in the process of configuring a High-Performance INS to receive RTCM sent by a NTRIP caster.

Configuration of the NTRIP 

You need to check that the High-Performance INS network connection is properly setup so it accesses the Internet (gateway and DNS) or else it will never be able to connect to the NTRIP server.

You need to have ready the following information.
•    NTRIP caster address and port.
•    User ID.
•    Password.
•    NTRIP mount point to use.


Once you have received the information, in the configuration menu of the SBG systems INS web interface, Aiding Assignment section, Differential Correction should be enabled to be received via NTRIP.
