Description
Specifies 8 characters of the frequency
value, coded in 4-bit BCD numbers.
The frequency is coded in GHz, where
the decimal point occurs after the third
character (e.g. 011,75725 GHz).
Specifies 4 characters of the orbital
position value, coded in 4-bit BCD
numbers. The orbital position is coded
in degrees, where the decimal point
occurs after the third character
(e.g. 019.2 degrees).
Indicating if the satellite position is in
the western or eastern part of the orbit
0 = Western position
1 = Eastern position
Polarization of the transmitted signal
0 = Linear - horizontal
1 = Linear - vertical
2 = Circular - left
3 = Circular – right
Roll-off factor used in DVB-S2
0 = 35%
1 = 25%
2 = 20%
3 = Reserved
Modulation system
0 = DVB-S
1 = DVB-S2
Modulation scheme used
0 = Auto
1 = QPSK
2 = 8PSK
3 = 16-QAM (n/a for DVB-S2)
Specifies 7 characters of the symbol
rate value, coded in 4-bit BCD
numbers. The symbol rate is coded in
Msymbols per second, where the
decimal point occurs after the third
character (e.g. 027,4500 Msps).
