fixed while moving. A new initialisation starts automatically when, after losing
the minimum number of required satellites, enough satellites are tracked again.
The instrument source describes where the coordinate triplet was measured or
entered. The options are GS, TS, Infinity or Level.
The procedures, codes and protocols that enable two entities to interact for an
exchange of data. Each interface is given a meaningful display name which
enables easy distinction between interfaces.

•
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.
