Emlid’s NTRIP Caster vs. An NTRIP Service: What is the difference?

What is NTRIP?

NTRIP is an industry standard used to send GPS / GNSS corrections over the internet in real time from a base to a rover.

Emlid's NTRIP Caster

Enables corrections to be sent between your own base and rover. No Additional costs / subscriptions required.

The Emlid Caster works as a pipeline that supplies corrections via the Internet. The core function of NTRIP Caster is to receive RTK data from your base and pass them to your rover.

This is a perfect way to work for those who have their own base and rover. You can set up a permanent base on a known point and work independently with multiple rovers. All your devices should be RTK-capable and have an Internet connection. You won’t have any additional expenses, as there are no subscription costs — the Emlid Caster is free and works worldwide.

An NTRIP Service

Enables working with just a Rover. Additional Costs / Subscriptions are required.

The NTRIP Service allows you to “rent” the nearest third-party base. In this case, you don’t need your own base station. A rover and an Internet connection are enough to start surveying.

Beyond that, it’s necessary to get a subscription to the NTRIP Service. The cost and coverage area depends on the specific service provider. Also, there is no global coverage. You need to search for a provider that works in your country.
