Paper Abstract

The Airborne Digital Sensor (ADS) a development to fulfil photogrammetric and remote sensing requirements. The new digital sensor is not only a camera for pretty nice pictures. It will be the next - full digital - generation as a measurement device for airborne photogrammetry and remote sensing. The high accuracy design of the focal plane system under flight and environmental conditions (pressure and temperature) will be presented. The ADS project will be introduced as a design of a modular customized CCD line scanner concept. It will be discussed on the ADS version with 4 multispectral CCD lines and 3 panchromatic CCD lines. The presentation will gives an overview of all dependencies and design constrains on the ADS Focal Pate Module (FPM). The ADS optical system has to support both photogrammetric accuracy and the requirement on the SNR for remote sensing applications. The principle to achieve good color pixel matching is described in relation to the customized CCD- and FPM- design. After a short description of the technical design and performances, some application examples are shown to demonstrate the main features of digital sensor: high accuracy, wide angle, high radiometric dynamics, high signal-to-noise-ratio, in-track stereo capability, multispectral capability.
