component
Signal type component
b
b. For L1 C/A (GPS and SBAS), set the signal component to D as there is only a data component. The
commands will be rejected if the field is not set to D for L1 C/A GPS and SBAS signal types.
For L2C, the D component corresponds to L2CM and P corresponds to L2CL.
For L2CL, the command accepts a 27 bit initial state, rather than the entire sequence.
L1C overlay NSC is not supported.

prn
PRN to apply the non-standard code to.
When 0 is specified, it applies to all PRNs for the
selected signal and system types.

6
nonstandard
The non-standard code that will be applied.
This code must be entered in hex format.
The specified sequence must be in multiples of
32-bits, achieved by adding 0’s appended to the end
of the non-standard code sequence if necessary.
