Using the Emild NTRIP Caster
Emlid Caster is a free NTRIP Caster service provided by Emlid, designed to let you publish your GNSS correction streams for use with your own rovers. Each user is allowed up to 5 base stations and 10 rovers simultaneously at no cost. In its free version, it’s not significantly more powerful than the built-in NTRIP caster.
The main advantage of Emlid Caster is its persistent internet address. This is especially useful because base stations typically have dynamic or private (“gray”) IP addresses and are often located behind a firewall. The paid version of Emlid Caster allows you to connect up to a thousand users at once. If you're curious, you can read the full documentation on the Emlid Caster website.
Before you begin using Emlid, you must determine the coordinates of your base station, as described in the section “Determining Coordinates”.
Go to the Emlid Caster website. If you don’t have an account yet, click “Sign Up”. If you already have one, click “Sign In”. The registration and login forms are nearly identical.
After signing up or logging in, you’ll land on the page https://caster.emlid.com/app/mountpoints, where your mount point names and passwords will be displayed.
Enable the number of base stations you need.
