Name Definition/Description Data Type Unit
rfAvailability-
It indicates if CLCWs will be used to determine the Enum n/a
ConfirmationRequired status of the onboard receiver. Possible enumeration
values:
– ‘clcwUsed’—CLCWs are to be used to
determine the status of the onboard receiver;
– ‘clcwNotUsed’—CLCWs are not to be used
to determine the status of the onboard receiver.
NOTE – If the CLCW is not used to determine RF
availability, a time period, calculated from
the data rate of the symbol stream and the
length of the acquisition sequence, as
specified in the acquisition-
SequenceLength parameter
(table 7-31), is used to confirm RF
availability (see reference [7]).

Name Definition/Description Data Type Units
carrierFrequencyRange Defined in table 7-28.
carrierUse Defined in table 7-28.
modulationIndexRange Defined in table 7-28.
modulationTypeOptions Set of modulation types that will be available for the set of Enums n/a
RF carrier during the lifetime of the Service
Agreement. It represents a set containing any
combination of the following values, with no
repeated components:
– ‘BPSK’—Binary Phase Shift Key;
– ‘QPSK’—Quaternary Phase Shift Key;
– ‘UQPSK’—Unbalanced Quaternary Phase Shift
Key;
– ‘OQPSK’—Offset Quaternary Phase Shift Key;
– ‘GMSK’— Gaussian Minimum Shift Key;
– ‘PSK/PM’—Pulse Code Modulation/Phase Shift
Key/Phase Modulation.
The set shall contain at least one component.
pcmFormatOptions Defined in table 7-28.

rEirp
Set of ratios between the power of the I-channel and
the Q-channel in the UQPSK modulation that will be
available during the lifetime of the Service
Agreement.
If UQPSK is not used, the value is ‘NULL’.
