NTRIP Server Via

CAREFUL : In the RTCM sense, an “NTRIP server” is a source
of corrections feeding an NTRIP caster (see RTCM paper
200-2004/SC104-ST ). But from the point of view of the
network terminology, an “NTRIP server” is a client, not a
server.
As explained earlier (see How to Start on page 65 ), in that
configuration you can define one or two NTRIP servers
sending their data streams either to an external NTRIP caster
(see first figure below) or to the embedded NTRIP caster (see
second figure below). All combinations are possible. Choose
the ones that meet your requirements.
• First, click on the
Connections
>
Ethernet
submenu.
• Set the following Ethernet parameters to allow the receiver
to access the network through its Ethernet port:
–
DHCP
: Enabling this option means the local network to
which the receiver is connected will automatically
allocate a dynamic IP address to the receiver. If this
option is disabled, you need to define the receiver’s
static
IP address
, and give information about the local
network (
Subnetwork Mask
and
Gateway
). You may need
to be assisted by a network expert -or IT Manager- to
define these parameters (as well as the three
parameters below).
If you activate the
DHCP
option, then it’s a good idea to
define a hostname for your receiver and declare it to
