Ntrip
The ntripclient is an HTTP client based on 'Networked Transport
of RTCM via Internet Protocol' (Ntrip). This is an application-level
protocol streaming Global Navigation Satellite System (GNSS) data over
the Internet. Ntrip Version 1.0 is a generic, stateless protocol based
on the Hypertext Transfer Protocol HTTP/1.1. The HTTP objects are
enhanced to GNSS data streams.
The primary motivation for Ntrip Version 2.0 is to develop a fully
HTTP-compatible Internet protocol standard that would work with proxy
servers and to add an optional data transport via UDP. Hence, one
Ntrip Version 2.0 transport approach is still based on HTTP1.1 on top
of TCP. The second Ntrip Version 2.0 transport approach is based on
both, the Internet Standard Protocol RTSP (Real Time Streaming Protocol)
for stream control on top of TCP and the Internet Standard Protocol RTP
(Real Time Transport Protocol) for data transport on top of
connectionless UDP.
Ntrip is designed for disseminating differential correction data
(e.g in the RTCM-104 format) or other kinds of GNSS streaming data to
stationary or mobile users over the Internet, allowing simultaneous PC,
Laptop, PDA, or receiver connections to a broadcasting host. Ntrip
supports Wireless Internet access through Mobile IP Networks like GSM,
GPRS, EDGE, or UMTS.
Ntrip is implemented in three system software components: NtripClients,
NtripServers and NtripCasters. The NtripCaster is the actual HTTP
server program whereas NtripClient and NtripServer are acting as HTTP
clients.
