Steps
Go to caster.emlid.com and sign up or sign in with an Emlid account
Retrieve the NTRIP mount point credentials issued for your account (separate credentials for base and rover)
On the base receiver, open Correction output settings, select NTRIP, and enter the Emlid Caster mount point credentials
On the rover receiver, open Correction input settings, select NTRIP, and enter the same mount point credentials
Confirm the base is streaming and the rover reaches a fixed or float RTK solution
Known gotchas
Both receivers must support NTRIP and have internet connectivity — Emlid Caster does not work over a purely local radio link
Emlid Caster is free but ties mount point access to your Emlid account; losing account access loses the mount point
This is a correction relay service, not a general geodetic API — there is no REST endpoint for querying position data
