Reacquisition Search
The antenna will search in a
(Search Mode 2)
“window” of 6˚ around the satellite’s
last known elevation.
Search Mode 3
The antenna conducts a complete
sky search, making continuous
revolutions at steadily increasing
elevations (from 20˚ to 70˚).
Fine-tuning/Satellite Verification
When a signal is detected, the
antenna interrupts the search mode
and begins a procedure to fine-tune
the position for maximum signal
strength. When the signal peak is
found, the IRD is queried to
determine if it can decode the
peaked signal. If it is able to decode
and lock onto the signal, then the
system enters park mode.
Using Your TracVision SA When Parked
When your vehicle is stopped, it is not necessary for the
TracVision SA to be turned on. After parking your vehicle and
confirming that the antenna is receiving the satellite signal, you
may turn off the TracVision SA unit to avoid unnecessary use of
power. The antenna will continue to receive the satellite TV
signals and relay them to the IRD.
“Instant On” Operation
As part of its operation, TracVision SA routinely saves the
satellite position to memory and retains it when the system is
turned off. When TracVision SA is powered up, the system looks
at the satellite’s last saved position. If the vehicle has not changed
its location, the antenna will immediately acquire the satellite and
receive the signal without initializing the antenna.
If the vehicle moves after TracVision SA is turned off, the
Antenna Unit will quickly carry out its normal initialization
routine to reacquire the satellite.

A Guide to TracVision SA
It is highly recomended that you
turn off the TracVision SA prior to
moving the vehicle. TracVision SA
will not track a satellite while the
vehicle is in motion.
