Emlid Caster is a cloud service that implements the NTRIP protocol and acts as a line of communication between connected to the Internet GNSS receivers.

With Emlid Caster, you can easily transmit RTK corrections—connect your base and rover to the same mount point, an automatically generated correction stream, and start surveying.
