Interference signal type configuration view
The interference signal type can be:
GPS : L1CA, L1P, L2P, L1P(Y), L2P(Y), GPS carrier, SBAS
GLONASS : L1, L2 or GLONASS carrier
Galileo: E1, E5a, E5b or a Galileo carrier
BeiDou : B1,B2 or BeiDou B1,B2 carrier signal
QZSS : L1CA or QZSS L1 carrier signal.
If your GSG unit supports jamming simulations (OPT-JAM), sweep and narrowband
noise are available as interference types.
Mode in the lower right-hand corner allows to further manipulate the interference signal by
offering the following options:
Modulated : standard signal type (default)
PRN
: Pseudo-Random Noise (see e.g.,
Navipedia: GNSS signal
for more information)
Unmodulated : carrier signal (carrier)
Sweep (OPT-JAM only): A dialog is shown asking for startOffset, endOffset, and
Sweep-Time.
Noise (OPT-JAM only): A dialog is shown asking for startOffset, endOffset and Sweep
Time.
Offsets are used to specify the bandwidth and position of the sweep/noise related to the
selected signal frequencies. The range of offsets is ±40 MHz, but can be less when the
scenario is executed since signals are not centered in the middle of a frequency band.
Note: Noise interference is not available if wide band noise is set to ON
under the Options > Transmit power menu.
Satellite ID/Frequency slot
For GPS, SBAS, Galileo, GLONASS, BeiDou, IRNSS and QZSS signals, the Satellite ID must be
specified.
For GLONASS carrier signals the Frequency slot must be specified.
In some instances, this field is not applicable, and will be grayed out (e.g., GPS carrier).
