intermediary between the GNSS receiver (NTRIP Source) streaming RTCM data and the
NTRIP caster.
2. The NTRIP caster is an HTTP server which receives streaming RTCM data from one or more
NTRIP servers and in turn streams the RTCM data to one or more NTRIP clients via the
internet.
3. The NTRIP client receives streaming RTCM data from the NTRIP caster to apply as real-time
corrections to a GNSS receiver.
u-center GNSS evaluation software provides an NTRIP client and server application that can be
used to easily evaluate a ZED-F9P base or rover. Typically a u-center NTRIP client connects over
the internet to an NTRIP service provider. The u-center NTRIP client then provides the RTCM 3.3
corrections to a ZED-F9P rover connected to the local u-center application. Virtual reference service
is also supported by the u-center NTRIP client.
2.2 Architecture
The ZED-F9P receiver provides all the necessary RF and baseband processing to enable multi-band,
multi-constellation operation. The block diagram below shows the key functionality.

An active antenna is mandatory with the ZED-F9P.
2.2.2 Typical ZED-F9P application setups
Two application examples are illustrated below as typical system implementations. Both are
representative of a simple "short baseline" set-up in which the base and rover receivers are within
