Acknowledgement Response
When successfully making a configuration change a single or multiple line response containing ‘
<OK>
’ can be
expected.
Rejection of Command
A rejected command will be flagged as such wi
th ‘
INVALID MESSAGE
’ or ‘
ERROR
’ appearing somewhere within
the echoed response, or no response will be received. These responses indicate that a command has not been
understood, or that a command has not been successfully implemented.
4.1.3 Saving Changes
Whilst configuring the LD8 via the WebUI terminal, any configuration changes made will not get automatically
saved. Although any configuration changes made may appear to immediately work,
without the use of a save
command these changes will be lost in the event of a power cycle . One command is used f or saving network
changes and another command is used for saving all other changes. Once either of the below commands has
been sent an acknowledgement response should be received:
Command Description
SAVEETHERNETDATA
Saves any Ethernet configurations
SAVECONFIG
Saves all settings excluding Ethernet configurations
4.2 L-band Configuration
Tracking of an L-band beam is required to receive VERIPOS service correction and activation data. This section
will detail how to establish and confirm successful L-band tracking to make use of VERIPOS services.
Auto Beam is the recommended way to manage L-band beam choices . When in this mode, the LD8 will
track up to three beams simultaneously with tracking determined based on available L-band satellites and
elevation. Data received from each of the L-band satellites will be utilised within the calculation eliminating the
need to switch beam in the event of tracking loss.
Using Auto Beam can mitigate against the impact of a single beam failure or masking. Additionally, when using
Auto Beam and transiting across different geographic regions, the LD8 will automatically select available L-band
beams. Whilst in this mode no manual beam selection is required.
The receiver also allows f or selection of a single L-band beam. If a single beam is selected, it will disable the
Auto Beam selection. VERIPOS have f ive beams available as detailed below and , in most regions, more than
one beam should be available. A global map with a beam overlay can be found in the
Appendix , however the
below table can be used as a general guide:
Beam Name Coverage
98W North America, Gulf of Mexico, South America
AORW North America, Gulf of Mexico, South America, North Sea, West Africa
25E North Sea, Mediterranean Sea, Africa, Persian Gulf, Caspian Sea
IOR Asia, Indian Ocean, East Africa, Persian Gulf, Caspian Sea, East Mediterranean
143.5 Asia, Australasia, Indian Ocean
The VERIPOS software
Verichart can be used to assess L-band availability by creating coverage charts specific
to a work location.
