Using the Web Server
• Whatever the way RTK corrections are transmitted to users
(rovers), you will always have to define a number of
general parameters pertaining to the base function. These
parameters are usually defined first. However when the
internal modem is used, it is advisable to configure the
modem first.
• The Web Server includes four submenus to configure a
base:
–
Full Setup
–
NTRIP Server
–
Data Streaming on IP
–
Transmitter
The
Full Setup
submenu is the most comprehensive one as
it gives you the ability to implement any of the possible
configurations.
The other three are abridged versions of the
Full Setup
submenu, customized for three specific configurations:
NTRIP server, data streaming and use of the internal radio
transmitter or of an external transmitter. These submenus
can advantageously be used instead of the
Full Setup
submenu to speed up the configuration phase.
On all four submenus, the first three frames (Base,
Antenna, Satellites) allow you to set the general
parameters. But note that only the
Full Setup
submenu
allows you to define a moving base.
• Through network connections , using the integrated
cellular modem or Ethernet port, the HDS800 can deliver
two distinct sources of corrections through two different
channels, designated as “Network 1” and “Network 2” on
the Base Setup-Full Setup page, and “NTRIP Server 1”
and “NTRIP Server 2” on the Base Setup - NTRIP server
page.
Differential Streams 1 and 2 should be defined
accordingly (port E, P or Q + message type), namely the
Differential Stream 1 is necessarily associated with
“Network 1” (or “NTRIP Server 1”) and Differential
Stream 2 with “Network 2” (or “NTRIP Server 2”).
Whereas the modem can only serve the “Network 1” or
“NTRIP Server 1” connection, the Ethernet port on the
other hand can serve both network connections, namely
port P for “Network 1”/“NTRIP Server 1” and port Q for
“Network 2”/“NTRIP Server 2”. Ports P and Q can not
only route their respective corrections (data streams) to an
external NTRIP caster, but also directly to the embedded
