5) Verify the VSAT position:
- Enter the CLI command dvb pos show
Example:
# dvb pos show
Latitude : 59d 52.15'N ( 59d 52' 9''N )
Longitude : 10d 29.05'E ( 10d 29' 3''E )
Altitude : 60 m
Timing Reference : SatLabs
PositionSearchN : 10
Position Search Offset : 0
Pos Large Uncertainty : First
Pos LTU Done : No

7) Save the VSAT position to flash memory:
– Enter the CLI command: save config
9.2.3 Forward Link Parameters
The Forward Link parameters are used to identify the Forward Link (outbound link) that is transmitted
from the Hub to the DVB-RCS VSATs. To set the symbol rate and receive frequency of the Forward
Link, use the following CLI commands:
dvb rx fwdlink <idx> <pri> [<symbrate> [<freq> [<mode> [<popid> [<satpos> [<rxpol> [<txpol>
[<satpolrot>]]]]]]
idx Table index [0 – 9]. The SatLink VSAT can store up to 10 Forward Link entries and the
table index is used to identify a single entry. For configurations with only one Forward
Link entry, it is recommended to set this parameter to 0. Adding a new entry with the
same index will overwrite an existing Forward Link entry.
pri Forward Link search order [0 – 9]. Search is started for priority 0 first and ends with
priority 9. For configurations with only one Forward Link entry, it is recommended to
set this parameter to 0.
symbrate Forward Link symbol rate [sps]
freq Forward Link frequency [kHz]
mode Valid modes: [dvbs, dvbs2]
popid Population ID
A popid value set to -1 means that the global popid value set using an earlier software
version is used. View the global popid value by typing 'dvb tx show'.
satpos Satellite orbital position of satellite in 1/10 degrees.
Range -180.0 .. 180.0 (-1800..1800). Negative values indicate West.
rxpol Specifying the polarization of the signal, 0 = horizontal, 1 = vertical
txpol Specifying the tx polarization relative to the rx polarization 0 = Cross polarization
(default), 1 = Co-polar
satpolrot Satellite polarization rotation angle (satellite polarization skew)
Range -15.0 .. 15.0 (-150..150). Negative values indicate West
del Delete table entry.
disable Disable table entry.
enable Enable table entry.
Verify the settings by typing the CLI command dvb rx show and type save config to save the
configuration.
