6. Enter the data for the satellite that you want to use as a calibration reference. Note the
following calibration requirements:
Elevation angle: 5 – 70 degrees.
Not allowed for calibration: Inclined orbit.
Satellite identifier: GSC, NID, Orbital position (DVB-S, DVB-S2)

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.
