This paper presents the current status of development of a remote sensing instru-ment suitable for Ultra Light Aircrafts (ULAs). F.A.S.T.E.R stands for Fully Automated Sys-Tem for Environmental monitoRing; the project (currently in a early development phase) is carried out through a collaboration between the Flight Mechanics laboratory and the Mi-crosatellite laboratory of the II Faculty of Engineering of the University of Bologna and the consortium Envi-net. Aim of the project is to demonstrate the feasibility of very high resolu-tion image acquisition from a standard equipped ULA, providing extended capabilities for onboard data processing (orthorectification, mosaic) and storage. The pilot interface is made of two different parts: an analytical model including the complete aircraft dynamics and a prediction system, and a graphical part made of a guidance tube, a rescue tube and the pre-dictors indicators. The graphical part is implemented in the Dynaworlds environment and is projected on a high brightness, sunlight readable touch screen LCD. F.A.S.T.E.R can be equipped with commercial DSLR (Digital Single Lens Reflex) cameras for Visible or Near Infrared imagery; FLIR (Forward Looking Infra Red) systems for thermal images or custom solutions like multispectral or hyperspectral imagers. The lens can be changed in order to reach the desired GSD (Ground Sampling Distance) up to 3 cm/pixel. All data are acquired by a PC-based system that acts as a storage device during image acquisition and becomes a post processing unit during in-flight transfer. Camera settings are also monitored by the same unit. In order to provide data acquisition timing and all ancillary information needed for im-age processing, the system is provided with an IMU, a GPS receiver and it is also ready to use standard air data information. A second PC-based unit, equipped with an RTOS (Real Time Operating System), acquires attitude and position data that is used to control camera timing.

Abstract
This paper presents the current status of development of a remote sensing instru-ment suitable for Ultra Light Aircrafts (ULAs). F.A.S.T.E.R stands for Fully Automated Sys-Tem for Environmental monitoRing; the project (currently in a early development phase) is carried out through a collaboration between the Flight Mechanics laboratory and the Mi-crosatellite laboratory of the II Faculty of Engineering of the University of Bologna and the consortium Envi-net. Aim of the project is to demonstrate the feasibility of very high resolu-tion image acquisition from a standard equipped ULA, providing extended capabilities for onboard data processing (orthorectification, mosaic) and storage. The pilot interface is made of two different parts: an analytical model including the complete aircraft dynamics and a prediction system, and a graphical part made of a guidance tube, a rescue tube and the pre-dictors indicators. The graphical part is implemented in the Dynaworlds environment and is projected on a high brightness, sunlight readable touch screen LCD. F.A.S.T.E.R can be equipped with commercial DSLR (Digital Single Lens Reflex) cameras for Visible or Near Infrared imagery; FLIR (Forward Looking Infra Red) systems for thermal images or custom solutions like multispectral or hyperspectral imagers.
