The GIT Sensor System
incorporates highly accurate IMU that
is coupled to GPS. This allows the IMU to operate without drift that
can
introduce unacceptable errors into the processing solution. This
technology
avoids the usual inaccuracies that many of the IMU systems have.
The GIT System
is capable of
collecting RGB data and NIR simultaneously. The frames
are triggered within a hundredth
of a microsecond of each other. No noticeable registration error can
be seen upon post flight analysis.

|
The
imagery is collected in 12 bit pixel
depth. It is then analyzed and reduced to 8 bit. Whereas the tendency
is to
market 12 bit imagery as superior, our tests have actually shown that the
added bit
depth contributes little or nothing to the quality for 99% of the end users.
As a
result, 8 bit data eliminates added baggage increasing portability and
speed.
Data
is collected in frames
that are an astounding 8,900 pixels if RGB, not low resolution color overlaid onto panchromatic! Triggering occurs
automatically from
the GPS system at a rate of twice per second, resulting in sufficient
overlap at
aircraft speeds up to 150 knots.
|
During
collection, data is stored on the GIT Sensor itself with a storage capability of one terabyte of
data
internally. There is no more need to plan on the added space and weight
of a
rack system for data storage. After collection, this data can be
downloaded
using a standard Firewire portable hard drive at transfer rates up to 390 MB per second. Once downloaded onto the
hard drive the
data can be uploaded to any office system via IEEE-1394 (Firewire)
interface. |
|
The GIT Sensor System is designed to be as automated as possible. While it can
operate in fully hands-off manner, an optional remote interface
(included with the system) also allows for the hands-on approach.
This interface
can be attached anywhere in the cabin due to the 4 meters of cable,
enabling
users to control flight lines as well as manage system status during
the
flight. If the remote interface option is not used, controlling the
system is
done by using the buttons on the face of the unit.
