Networked Transport of RTCM using Internet Protocol
is a protocol streaming real-time corrections over the Internet.
•
is a generic protocol based on the Hypertext Transfer Protocol HTTP/1.1.
•
is used to send differential correction data or other kinds of streaming
•
data to stationary or mobile users over the Internet. This process allows
simultaneous computer, laptop, PDA, or instrument connections to a
broadcasting host.
•
supports wireless Internet access through mobile IP networks like digital
cellular phones or modems.
The Ntrip Server could be the GS itself. This setup means the GS is both the
Ntrip Source generating the real-time data and also the NTRIP Server transfer-
ring this data to the Ntrip Caster.

The Ntrip Caster
is an Internet server handling various data streams to and from the Ntrip

Servers and Ntrip Clients.
checks the requests from Ntrip Clients and Ntrip Servers to see if they are
•
registered to receive or provide real-time corrections.
•
decides whether there is streaming data to be sent or to be received.
The Ntrip Client receives data streams. This setup could be, for example a real-
time rover receiving real-time corrections.
