SPECEYE

This project was completed in collaboration with the Bremerhaven University of Applied Sciences. The objective of the project was the development of an autonomously operating integrated sensor system for airborne marine and coastal monitoring. In general the system shall operate independently of the user platform. The basis for the development is the concept of a modular sensor system for autonomous with a payload of up to 10 kg.

A main objective consists of the capability to transfer the sensor system onto a large number of various civilian applications. In this context, autonomous airborne platforms with a payload of 5 to 10 kg promise a maximum distribution and important market share. This outlook is based on the fact that these small platforms (MTOW < 25 kg) legally belong to the group of the model aircraft which can be operated in the near future without large bureaucratic effort such as certification in various applications.

OPTIMARE developed an integrated sensor system for simultaneous acquisition of georeferenced multi-spectral and topographic data.

• The sensor system consists of imaging sensors (cameras):
• UV-sensor (ultraviolet spectral region; 250 nm to 450 nm)
• RGB-sensor (visible spectral region; 400 nm to 850 nm )
• NIR-sensor (near-infrared spectral area; 800 nm to 1100 nm)
• LTS (Laser-Topographic-Scanner; scanning distance measuring system for 3D-capture of the topographic data)
• Integrated precise navigation with position accuracies of +-1 cm

A demonstrator is integrated inside a standard aluminum housing:

• 1 JAI- AD80CL camera (RGB, NIR with CameraLink interface)
• 1 JAI-TM1405GB camera (UV)
• 1 Laser scanner (UAV-LIDAR)
• 4 GPS antenna array
• 1 Crossbow AHRS440
• 1 Time client
• 1 Data link
• 4 System for data acquisition

The development was funded by the BIS Bremerhaven Gesellschaft für Investionsförderung mb and the Land of Bremen according to grant number 68201-Z.
