Spectra Precision ProFlex 800 CORS - Manual (Page 35)

31
In its simplest configuration, the embedded NTRIP caster
can be used to emulate the Direct IP mode (i.e. IP connection
to a unique source of corrections), with the additional
advantage that, contrary to conventional Direct IP, the
embedded NTRIP caster can offer an effective protection of
the source of corrections by restricting its use to the sole
authorized users.
In this application, the ProFlex 800 CORS makes use of both
its embedded NTRIP caster and an internal NTRIP server
(see figure below):
• In the NTRIP caster, a single mount point is available and
all declared users are allowed to use this mount point.
• The internal NTRIP server is connected to the NTRIP
caster’s unique mount point.
The result is that only the NTRIP caster users are allowed to
use the source of corrections.
