Our AISA hyperspectral systems are complete, push broom imaging systems, consisting of a hyperspectral sensor head, a miniature GPS/INS sensor, and a data acquisition unit in a rugged PC. These systems are user and field friendly. They are quick to install and remove from any aircraft and they provide timely, accurate and reliable information. The systems include an in-flight configuration setting, which allows alterations to be made easily for each exercise. AISA systems provide solutions for several application fields such as forestry, precision farming mineral mapping and environmental monitoring.
Aisa Systems Installation Examples
Specim's AISA systems are designed and tested for many different operational conditions, in addition to standard mounting in manned or unmanned airborne platforms.
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 movements. 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.
This requires more careful installation design in order to take into account, for example, system vibrations. In such cases, applying a seperate mount with shock absorbers at the fixing points can be very effective.
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 futher 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 aircrafts, which have no room to accomodate the system inside the cabin.
