G Channel Budget
The term channel describes a hardware unit that is required to process and generate
the signal of the following configuration elements per GNSS stream :
●
One vehicle
●
One antenna
●
One RF band
●
One signal of one satellite
Where each GNSS stream requires one baseband and is routed to one RF output. The
number of GNSS streams depends on the installed options, see Table G-1 .

Where:
●
1) Total number of SV per scenario; further GNSS options, like R&S SMW-K66, do
not provide additional SV.
The number of SVs is limited according to the selected signals as each SV occu-
pies as many channels as its enabled signals on that stream.
●
2) The maximum number of channels depends on the availability and the number of
installed options R&S SMW-K99.
Table G-2 lists the capability of one option, depending on whether P-code and L2C
signals are generated.

no no 36
no yes 24
