Graphical System Display
The following area shows the blockage map of the system, the current satellite position
relative to the antennas and the operation modes of the antennas.
The following display reflects a configuration in which:
Ant1 and Ant2 are active
Ant1 is transmitting (UL) and receiving (DL) - bi-directional arrow between Ant1 and
satellite
Ant2 is only in receiving mode (DL) – directional arrow towards Ant2. However, a
signal will not be received since Ant2 is now attempting to receive in its defined
blockage zone (yellow area)
Ant1 is transmitting and receiving; but Ant2 is open to receive currently blocked
(within yellow blockage zone)

Description
Satellite real-time
position
Satellite position relative to blockage zones of antennas
Trajectory points
Representation of satellites calculated Route (NOTE) over the
Earth horizon.
Blockage Zones
Shows the blockage zone for each antenna, where the colors
correspond to the blockage colors associated with each antenna.
Bore-site Line to
satellite
Shows transmission path between the antenna and the satellite.
NOTE: For terminology description of various antennas described
below, refer to section
1.2.1.
Primary Antenna – A solid Bore-site line with arrows pointing
in both UL and DL directions
Secondary Antenna – A solid Bore-site line with a single arrow
pointing in DL direction. When in Blockage
or Solar Outage, the Secondary Antenna
reverts to Program Route. This is
graphically marked by removing the arrow
