Changing the Transmit Power setting becomes effective immediately, and
also impacts noise generation levels (if in use – available with GSG-5, GSG-55,
GSG-56 and GSG-62, 63, and 64).

The example above illustrates two GPS signals (
G23
and
G5
), one SBAS signal (
S135
), one
multipath signal (
G7D
) and one interference signal (
G3
).
3.4.2.3 Last View
The last view (e.g. View 4/4 ) shows a skyplot , illustrating how the simulated satellites are
located in the sky.
Press the LEFT/RIGHT arrow keys to scroll through the skyplots, if more than 2 con-
stellations are simulated.
The center of the plot represents the current receiver position, and the outermost circle
the horizon, i.e. the
elevation of a satellite located near this circle is low. The lines rep-
resent the azimuth (North = 0°). For example, in the GAL ileo plot shown above, satellite
number 22 would have an elevation of approximately 45°, and an azimuth near 300°.

Scenarios are the simulation scripts which you run on the GSG simulator in order to test a
GNSS receiver. GSG has pre-installed scenarios which can be executed 'as is', or which you
