ELV

: Satellite elevation

The angle between the current position's horizontal plane and the satellite pos
ition. A low angle is close to 0°, a high angle close to 90° [range = 0 to 90°]

5.

AZM

: Azimuth

The angle around the vertical axis of the current position [north = 0°, east = 90°,
south = 180°, west = 270°]

6.

dBM

Transmit Power ratio

in decibels for the frequency band indicated (L1, L2, L5 and

ALL). During scenario execution, the Transmit Power (= signal level) can be adjus
ted for all satellites per frequency band (including ALL bands), or per individual
satellite:

Press

±/format

to toggle through the frequency bands;

to adjust the power for all satellites on the current band, press

±/power

.

Press LEFT/RIGHT

arrow

keys to select a satellite. An

information box

is dis

played, showing the satellite ID, elevation, azimuth and frequency bands
in use.
To adjust the

Transmit Power

for this satellite, press the UP/DOWN

arrow

keys. Press

enter

to confirm.

This power adjust functionality is useful for

fine tuning the scenario power level
