Satellite Navigation
Remote command:
[:SOURce<hw>]:BB:GNSS:SETTing:CATalog:PREDefined?
[:SOURce<hw>]:BB:GNSS:SETTing:LOAD:PREDefined

Scenario

Indicates one of the following:
●
None: preset (default) configuration, see
●
Scenario name: if predefined scenario is selected, see
●
Filename: if saved settings configuration is loaded, see
●
"User-defined" indicates that at least one parameter is changed after a configura-
tion or predefined scenario is loaded.
Remote command:
[:SOURce<hw>]:BB:GNSS:SCENario?

Test Mode

Set this parameter to match the operation mode in that the DUT works.
Irrespectively of the selected mode, initial satellites constellations are defined by the
predefined or imported constellation data. The number of active satellites with their ini-
tial position and messages are retrieved from the constellation data, too. You can edit
the satellite constellation and signals in both modes.
Switching from one test mode to the other presets all satellites parameters to their
default values.
The modes differ in terms of signal content and scenario complexity:
"Navigation"
"Tracking"
Remote command:
[:SOURce<hw>]:BB:GNSS:TMODe
Simulation Configuration
Access the "Simulation Configuration" dialog for defining the active navigation system,
used bands and configure the satellites.
A summary of the current configuration is displayed.
User Manual 1178.6379.02 ─ 01
The satellite signals are configured to correspond to the signal at a
particular location ("Receiver > Location").
The generated signal corresponds to a realistic scenario. The DUT
can achieve position fix, since the satellite constellation comprises of
at least three satellites. The signal is suitable for signal acquisition
and TTFF tests.
Generated is signal without positioning data. Receiver configuration is
not required.
Navigation and acquiring of position fix is not possible. The signal is,
however, sufficient to test the ability of the DUT to find the channel
and to decode the signal. It is also sufficient for sensitivity testing.
Use this mode also if high signal dynamics are required, for example
for the simulation of spinning vehicles and precision code (P code)
such as in some aerospace and defense applications.
