We maintain two open SNIP® NTRIP Casters for community use. The first is at:
#1 NTRIP.itsware.net port 2101
You do not need an account or a password to connect and use it; it is free.
Most public and private NTRIP Casters are “closed” in that you must first register with the owner/operator before your NTRIP client software can connect and get any data. You can elect to run your copy of SNIP in either open or closed mode as well.
Contact the operator of any NTRIP Caster you wish to connect to in order to understand how to register on their network. Some networks, or some streams within some networks, involve monetary compensation for the operators.
The NTRIP.itsware.net caster is intended to support our user community throughout the world. The data streams chosen represent a cross section of locations where we are developing other work. In the caster holdings you can find baselines ranging from just over one meter to 50km and more, using both L1 and L2 and some low cost L1 only sources such as uBlox. Both Legacy RTCM and the newer MSM message content. You can use these data products to confirm that your copies of SNIP or RTKLIB or other GNSS tools are working as expected. For example, you can easily connect to any two nearby local reference stations in our coverage area, as well as our worldwide broadcast ephemeris stream, and perform various types of RTK navigation operations on the data sets.
#2 RTK2go, a public relay point:
RTK2go (rtk2go.com:2101 or 126.96.36.199:2101)
We also operate a free open NTRIP Caster at RTK2go.com which any party can use to send their data to. Use this resource to send your Base Station data to others. This allows those without a static IP, or if they do not want to operate their own Caster, to provide corrections to others (or themselves). The RTK2go.com Caster is one of a growing number of free open Caster services now on the market as the deployment of RTK style navigation grows.
Usage is free, but you must first register to send your Base in. See the site for details.
Your Own NTRIP Caster
Of course, your likely reason for reading this web page is to use SNIP to set up a network meeting your own needs. Please download an evaluation copy and then see other articles in the knowledge base for details of how to go about this. Most folks elect to run their own copy of SNIP, but if you wish our staff to manage your caster or to lease time on one of our world-wide regional deployments, just contact us.
