RTK2go Free Community NTRIP Caster for RTK live corrections

http://rtk2go.com:2101/SNIP::STATUS

A free, cloud-based community NTRIP Caster that serves as a central hub for distributing high-precision GNSS correction data. Built on the professional-grade SNIP Caster software, the platform allows individual base station operators to “push” their RTK (Real-Time Kinematic) correction streams to a public server, making them accessible to any number of “rover” clients over the internet. This service is particularly valuable for users who lack a static IP address or the technical resources to host their own caster, enabling them to achieve centimeter-level positioning accuracy for applications like precision agriculture, surveying, and drone navigation without the overhead of maintaining private infrastructure.

Tip: click the button on the right of any node, to access the worldwide map, and maybe see a node closer to you, correctly placed and functional, but that may not have entered a correct location name.

How to use RTK live corrections

For rover users (most frequent case): no registration is required; they simply configure their NTRIP Client to connect to rtk2go.com:2101, enter the specific Mount Point name they wish to use, and provide a valid email address as the username with “none” as the password. Users can verify active streams and their geographic locations by checking the real-time status map or caster table provided on the RTK2go website.
For base station operators (make your data available to you and to others): you must first register a unique “Mount Point” name on the website and activate it via a confirmation email. Once registered, the operator configures their GNSS base station (or a software bridge like SNIP or RTKLIB) as an NTRIP Server to “push” data to rtk2go.com on port 2101 using their assigned credentials.

Disciplines: Surveying, Precision agriculture, Geodesy, Robotics, Drone mapping.

RTK2go compared with Trimble VRS Now, HxGN SmartNet and Emlid
RTK2go	Trimble VRS Now	HxGN SmartNet	Emlid
Service model: A community NTRIP caster running the Pro edition of the SNIP Caster software. Base station owners push their own RTCM streams to it and rovers pick a mount point, so each stream is a single base, not a computed network solution.	Service model: A network RTK service using permanent reference stations, with corrections computed by Trimble software for the rover position. The rover does not depend on one nearby base.	Service model: A subscription network RTK service built on a network of reference stations, with Leica GNSS Spider software on the server side. The network is operated and monitored by Leica.	Service model: The Emlid NTRIP Caster, a hosted caster that passes corrections from your own base to your own rovers. Like RTK2go it relays single-base streams, but it serves a private group.
Access and cost: Free. Rovers need no registration: they use a valid email address as user name and any password such as none. Base operators must register a mount point first so the operator has a contact address.	Access and cost: Commercial subscription. The vendor page gives no prices and asks visitors to contact Trimble.	Access and cost: Subscription based. Leica manages the subscriptions, and prices are not listed publicly on the pages consulted.	Access and cost: Free according to the vendor page. Limits are 5 bases and up to 10 RTK rovers connected at the same time.
Coverage and data quality: Depends entirely on which volunteer bases are online. The operator reports over 500 bases online at any time, more than 5,000 registered, and 700 or more public streams. Quality and position accuracy of each base are the owner responsibility.	Coverage and data quality: Available across much of North America, Europe, Australia and New Zealand where cellular coverage exists. The page rates accuracy at better than 2 cm.	Coverage and data quality: Coverage is regional and varies by country, with national services such as SmartNet North America and a UK service. Accuracy figures were not found on the pages consulted.	Coverage and data quality: Coverage exists only where you install your own base. Accuracy depends on your base position and on the distance to the rover.
Correction formats and receivers: The operator mentions RTCM 3.x streams and clients configured with host, port and mount point. Any receiver or software with an NTRIP client can connect, including RTKLIB.	Correction formats and receivers: CMRx, CMR+, RTCM 2.3, RTCM 3.1 and RTCM 3.2 MSM over NTRIP, for Trimble and third-party receivers.	Correction formats and receivers: The vendor states that all data formats are accepted, with Leica MAX and iMAX products available for receivers that cannot use newer formats.	Correction formats and receivers: Base and rover must use the same correction format, such as RTCM3 or CMR. It works with Emlid Reach and with other NTRIP-capable receivers.
Service guarantees: No liability is accepted by the operator, and abusive users may be blocked. It is a best-effort community resource, not a service with contractual uptime.	Service guarantees: Commercial offering with a satellite-delivered backup (xFill) when the network link drops.	Service guarantees: Commercial service monitored around the clock by the vendor, according to the vendor announcement.	Service guarantees: Free tier with Caster Terms of Service. The limits on bases and rovers apply.
When to choose it: Choose it to test RTK, to publish your own base, or when a public base is close to your site and the work does not carry contractual accuracy requirements.	When to choose it: Choose it for professional survey or construction work that needs a supported, network-computed solution.	When to choose it: Choose it when your fleet is Leica equipment, or when a subscription network is needed in a region it covers.	When to choose it: Choose it when you own the base and only need a simple, free way to relay it to a few rovers.
