We maintain an open NTRIP Caster for community use at:
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. 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.
We also operate a free open NTRIP Caster at RTK2go.com which any party can use to send their data to. 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.
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.
