Ntrip - Leica GR10 Operational Manual

Ntrip

Networked Transport of RTCM via 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 GPS instrument itself. This setup means the GPS instrument is both the Ntrip Source generating
the real time data and also the NTRIP Server transferring this data to the Ntrip Caster.
Ntrip and its role in the Internet
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.
Ntrip Client
The Ntrip Client receives data streams. This setup could be, for example a real time rover receiving real time corrections.
In order to receive real time corrections, the Ntrip Client must first send
•
a user ID
•
a password
•
an identification name, the so-called Mountpoint, from which real time corrections are to be received
to the Ntrip Caster.
