Active Signals
Frequency bands can be turned ON/OFF separately, so as to configure which types of RF
signals specific to each supported satellite system shall be active/inactive when a scenario
is running.
Depending on the configuration of your GSG unit, all of the frequency bands listed above
can be turned ON/OFF.
To turn ON/OFF a signal band, navigate to: Select > [ Select Scenario ] > Configure Scen-
ario : View 3/3 > [ Satellite System ]: Enter a number of satellites > 1 (see "Number of
Satellites" on page 76 ).
The satellite constellation (see "Satellite Constellations" on the facing page ) must be con-
figured accordingly, in order to allow for, e.g., the L2C band to be simulated. In other
words, if you chose to disable satellites that can generate this signal, it will not be gen-
erated, even if you activate the signal. Hence, it is recommended to leave all signal types
ON (default), thereby letting the configured satellite type determine which RF signals are
active.
Use cases for turning OFF the transmission of individual frequency bands are:
simulating a one-band antenna
reserving the maximum number of channels for other requirements (e.g., L1-only
transmission)
Considerations:
Altering active RF signals will not alter the navigation message. Hence from a
receiver point of view, choosing to de-active L2 and L5 will mimic the situation of
using a single band (L1) antenna.
Settings are GNSS-specific, not satellite-specific.
For GLONASS, C/A code is always used.
