NTRIP server settings

An NTRIP server is a broadcast internet server that manages authentication and password control for differential correction sources such as VRS networks, and relays corrections from the source that you select.

NTRIP is the acronym for Networked Transport of RTCM via Internet Protocol.

Configure NTRIP settings when you create the GNSS correction source for the internet data link. When you start the survey, a connection is established to the NTRIP server. In addition, a table appears showing the available sources of corrections from the server, referred to as "mountpoints". These can be single station sources, or network sources (for example, VRS). The type of base station data provided by each mountpoint is shown in the source table. To sort the available sources, tap the sort field above the list and choose to sort by Distance, Format, or Mountpoint. Tap a row in the table to view more detailed information for the selected mountpoint.

To use the selected source, tap Accept. The base data from the selected mountpoint streams through Origin to the connected GNSS receiver.

If authentication is required to connect to a particular mount point, and this was not configured for the GNSS correction source, the Origin software displays a screen where you can enter your username and password.

NTRIP protocol versions

When the Origin software connects to the NTRIP server, it checks if the server supports NTRIP version 2.0, and if it does then the software communicates using version 2.0 protocols. If it does not, then Origin communicates using NTRIP version 1.0 protocols.

To force the software to always use NTRIP version 1.0, select the Use NTRIP v1.0 check box when you configure the NTRIP settings for the GNSS correction source.

NTRIP version 2 includes improvements to the original standard. Origin supports the following NTRIP version 2 features:

NTRIP 2.0 feature	Advantages over 1.0
Full HTTP compatibility	Addresses proxy server issues. Supports virtual hosts using the "Host directive".
Chunked transfer encoding	Reduces data processing time. More robust data checking.
