Embedded NTRIP
Caster
Introduction
The Embedded NTRIP Caster allows you to build your own
NTRIP network solution around the ProFlex 800 CORS
station.
The embedded NTRIP caster can handle a total of 100 users
and 10 mount points. The number of 100 users should be
understood at the total number of possible users, irrespective
of the mount points they are using. For example, if 90 users
are connected to mount point n, then only a total of 10 users
can be connected to any of the other mount points.
One of the distinguishing features of ProFlex 800 CORS is its
capacity to accommodate internally two NTRIP servers
directly “feeding” the embedded NTRIP caster. The other
NTRIP servers, if any (up to 8), will therefore be all external
to the ProFlex 800 CORS.
• The two internal NTRIP servers will both provide
correction data from the “base” section of the ProFlex
800 CORS (see figure below), typically in different
formats.
• Internal NTRIP server 1 uses Ethernet port P to deliver its
correction data to the caster. The correction data are
internally routed from the base either through the internal
modem or directly via Ethernet.
• Internal NTRIP server 2 uses Ethernet port Q to deliver its
correction data to the caster. The correction data can only
be routed internally from the base via Ethernet.
The figure below shows the internal architecture of the
ProFlex 800 CORS when the Embedded NTRIP Caster
firmware option is enabled and running and two internal
NTRIP servers are also set up and running.
