RTK2go® is a community NTRIP Caster created to allow you to publish your GNSS correction streams for others to use with their NTRIP Clients.  It is built using the same Pro edition of the SNIP Caster you can find on the site.  Why do we do this?, because many of the RTK2go users here end up operating  SNIP network of their own.  You can download and evaluate your own copy of SNIP® from here.  It is one part of the overall simple NTRIP™ project created by SubCarrier Systems Corp. (SCSC).

RTK2go:   200+ Public Base Stations,  10,000+ Users,  45,000,000+ Sessions,
Professional Grade, and Free to use

Send your Base Station data to RTK2go® if you do not wish to run your own NTRIP Caster.
Please download and use SNIP® if you want to run your own NTRIP Caster.

All New Base Station Data Providers:
Please Register before use (click here)

Having a prior registration is now required for all data providers so that we have a valid email on record to contact you when your Base Station is not working.  The process is quick, free, painless and we will not send you spam.  But with millions of bad connections occurring every month, we have to implement this to better manage the service for all.

If you have been using this service to provide data,

RTK2go: 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.

Note of the Day…

Note:  Bad Choices for Base Station names

In recent weeks we have seen a large number of Base Station streams banned due to the selecting a “common” name rather than a unique one.  Every station must have a unique name on the Caster it appears on, and SNIP will force this when required.  With over 800 reservation now in place on RTK2go, most any common name you can think of is already taken by someone else.  When you try to use that name, the default password will not match (nor the IP) and you will be rejected.  Do this many times in a row and your IP will be banned for a period of time (your IP can be banned for many other reasons).  Worse yet, when two people try this on a common name which is not yet reserved, they can each knock the other off.  Name conflicts are an enviable problem when running an open Caster.    We have now reserved a number of these names to prevent this problem from growing.    Please do not use any of the following as your own Base Station nameBase, ESO, ESOTEST, Esotest, F9, F9P, Leica, mpt, MPT, NVS, Rover, SNIP, TopCon, Topcon, Trimble, Ublox, ublox, UBX.  This is only a partial representative list.  An easy way to overcome this is the add a few unique characters to the name such as: ESOTEST ⇒ESOTEST-myCity.

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 several thousand 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.  Of course the paid models do have many additional useful features which we hope will convince you to purchase your own copy.

Worried about the lack of available static IP at your planned site?  No problem, we can help your setup a DDNS connection and register a proper name for your Caster to overcome this, just ask our support staff for details.
