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 purchase on the use-SNIP.com site.  Why do we do this? Because many of the RTK2go users here end up operating a SNIP network of their own.  You can also download and evaluate your own copy of SNIP for free from here.  It is part of the  simple NTRIP™ project created by SubCarrier Systems Corp. (SCSC).   You do not need a copy of SNIP to use RTK2go, only a suitable NTRIP Client (Rover device) or NTRIP Server (Base Station).

RTK2go:   500+ Free Base Stations on-line at any time,
5,000+ Registered Base Stations
50,000+ Users from nearly every country,

   —  ! IMPORTANT !  —
Attention All NTRIP Clients (data consumers):
Follow this Log in Process

IMPORTANT It is REQUIRED that all data consumers (Rover devices) provide a valid email address in the NTRIP Client user account name field when accessing the Caster.  Please ensure your connection details have a suitable email as the user name.

When the SNIP Caster detects a user name that is a valid email and there is a reoccurring problem with the connection, you will be mailed an email informing you what the problem is and how to correct it.  Should your IP be blocked after further bad connections, you will receive one email to notify you.   You will receive at most one email per every 6 hours if the problem continues.  We will not send you spam or use or share this email in any other way.  With millions of bad connections now occurring every month, we have implemented this to better manage the service for all.  Data providers (Base Stations, NTRIP Servers) should still use the same registration information you received when you registered the Base.

Minor details:

Note: A valid email starts with a char or a digit, and has only ASCII in it or the five
chars: ‘+’ ‘-‘ ‘_’ ‘@’ or ‘.’ and is generally in the format: name@domain.xxx
If you send in other chars (such as the user name “[“) your device will be rejected.

Some NTRIP Client models cannot enter the char “@” so please use “-at-” and the Caster will
accept it.  So if your email is “myName@gmail.com”  you would enter “myName-at-gmail.com”
as your user account.  And, some NTRIP Client models cannot enter the char “.” so please
use “-d-” and the Caster will accept it.  So if your email is “myName@gmail.com”  you
would enter “myName-at-gmail-d-com” as your user account.

Please use the password “none” if your device requires that a password be entered.

Connecting multiple devices or to multiple bases?  Yes; you can reuse the same email for these.
If the SNIP Caster has to send you an email it will also tell you what mountPt and end user
equipment that was involved so you can tell them apart.

 

Attention All Base Station Data Providers:
You must Register before use (⇐ click here)

Having a prior registration is required for all data providers (Base Station owners) 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.  With millions of bad connections now occurring every month, we implemented this to better manage the service for all.  Data consumers (NTRIP Clients) do not need to pre-register but should provide a valid email in the user name field as per the above note.

 


What is RTK2go?

RTK2go: This Caster accepts data from any valid NTRIP 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 NTRIP 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.

RTK – NTRIP – RTCM – Precision GNSS, summarized in 1 minute

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….

On SNIP

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 an AWS 2-core Windows VM machine with a reliable internet connection.  There are several thousand SNIP Caster deployments running both public and private NTRIP 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 require any of SNIP‘s advanced features such as PFAT translations, a NEARest baseline connection, advanced user accounting, adaptive IP firewalls, status reporting, sending status eMails to your users, or complete 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 use 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 an 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.

Do not have a dedicated server machine? No worries, SNIP works on common Windows 7, 8 and 10 machines as well as all Windows servers and various low cost virtual machines.  The machine running this web site and also the RTK2go Caster with 500+ active Base Stations is just 2-core large Amazon AWS VM with an average ~20% load utilization.  The prior machine running the same web site and the RTK2go Caster with 300+ active Base Stations was a common Win7 box (4-core i5) with an average 12~15% load utilization.

Please Note:
You do not need a copy of SNIP to use the RTK2go Caster with you base and rover devices.
Chances very good that all your NTRIP devices can connect to RTK2go directly.
You only need a copy of SNIP if you wish to run your own NTRIP Caster.
