This Caster accepts data from any valid source including other SNIP nodes, the Simple NTRIP Caster, in the PUSH-Out mode, as well as from any other NTRIP Server software.  It is not a web site.  It is using a SNIP Caster as a software service you can freely use (SaS).  If terms like Caster, Client or NTRIP are unfamiliar to you, just click on these links for further explanations.

But if these terms are familiar to you, you probably want to know how to log on, see the below.

This is a simple “static page” web site as all the interesting things take place using the normal NTRIP protocol layers hosted on the same machine.

Terms of Use: By sending your data stream to this Caster you affirm that:
a) You have the right to do so, and
b) You consent to allow others to freely use your data, and
c) The caster owner / operator shall be held harmless for any faults or loss – real or perceived.
The caster owner / operator (SCSC) reserves the right to remove or block any party for abuse.

Useful details….


The RTK2go Caster is implemented with the SNIP NTRIP Caster using the same software you can purchase from our SNIP web site.  It is running on a common Windows 7 OS on an i5 machine with a reliable internet connection.  There are hundreds deployments running both public and private SNIP Caster networks all over the world.  Over the past few years, SNIP has lowered the cost of professional grade NTRIP Caster ownership for GNSS professionals everywhere.

If your network needs are small (3 Base Station streams or less) and if you do not required any of SNIP‘s advanced features such as PFAT translations, a NEARest baseline connection, status reporting, or RTCM 3.x message decoding, the Lite model may be ideal for your needs.  The Lite model of SNIP is free to use, even for commercial applications.   Download a copy here.  You can read more about SNIP‘s various features and setup details here.


Are always welcome, please send them to support [at]  We use your comments to help us make SNIP the best NTRIP Caster in the world.  Want to run your own copy, that’s why we are here.
