AISA SYSTEMS

Installation Examples

Specim’s AISA systems are designed and tested for many different operational conditions. In addition to the standard mounting in a manned or unmanned airborne platforms.

CABIN MOUNTING

In a standard aircraft cabin mounting the AISA sensor is installed vertically to look through the aircraft camera port. As AISA sensors are pushbroom devices, the image of the view is formed along with the aircraft movement. The corrections for the changes in the aircraft’s roll, pitch and heading are performed as a preprocessing step in the AISA pre-processing tool.

When extra isolation for passive vibration is needed, a gyro-stabilized mount can be installed in the camera port to mount the AISA sensor. If required by the AISA user, the sensor can be mounted horizontally, using a folding mirror provided by Specim.

HELICOPTER MOUNTING

This requires more careful installation design in order to take into account, e.g., the system vibrations. In such cases, applying a separate mount with shock absorbers at the fixing points can be very effective.

GIMBAL MOUNTING

Due to its compact size, the AISA sensor and GPS/IMU unit can be mounted on a gimbal. This provides an easy and fast solution to install and remove the sensor from the aircraft or helicopter, perfect for emergency response situations or when time is crucial in your flight campaign. In addition to the benefits of image motion compensation, the gimbal further provides passive vibration damping and improved vertical alignment of the airborne sensor. This gives the sensor operator more precise control during image acquisition and ensures better image quality.

INSTALLATION IN A POD

AISA systems have also been successfully operated when installed in a pod outside the aircraft. This kind of mounting offers the possibility to collect hyperspectral data in very compact and light aircraft, which have no room to accommodate the system inside the cabin.
