If you do not want to enter the satellite data on the calibration page you can
select a dedicated satellite service profile for calibration and select it.
Check that the satellite transponder is visible from the location of the
installation and that it is at an elevation angle between 5 and 85 degrees.

Important
The calibration function is not able to verify the correctness or
precision of the supplied longitude. It is therefore important to supply
the correct longitude including the first decimal.
1. Use Orbital position and NID if you want to use NID or orbital position or other KA
band satellites with DVB-S2 support. The DVB symbol rate must be >5 Ms/s. For NID
use preferably a unique NID (ONID). An azimuth calibration without NID can be useful
in regions where the satellite operators do not broadcast NID (US, China, Australia
etc.). For NID=0 the NID is not used when checking the satellite link. For NID 1 to
65535 the supplied NID is matched against the Network ID broadcast by the satellite.
For orbital position the supplied longitude is matched with the orbital position
broadcast by the satellite. Not all service providers broadcast the orbital position.
