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.
