Introduction

from the airplane (without fuselage modifications or the need of specific navigation

instruments) in which is installed. Thus it will be possible to move the system from an

airplane to another without affecting performances.

This work is organized as follows: in Chapter 2 background experiences are

presented introducing how the idea to realize such a system was conceived. Past

activities, like the development of the ALMASat-EO Multispectral Camera, permitted to

acquire important skills in the field of digital sensor electronics and optical design. Skills

that have been consolidated during the STARS and LCCES projects which involved the

use of high frame rate and Thermal Infrared sensors, jointly with the development of

image processing algorithms.

Chapter 3 describes the state of the art technologies currently used in remote sensing

and photogrammetric devices. In this section a survey on existing instruments is

presented ranging from aerial to satellite platform, highlighting pros and cons of each

solution. Field applications are investigated too, trying to identify in which direction

research is moving and what are the most interesting innovation that are coming in the

future.

In Chapter 4 the FASTER system is discussed. FASTER is a remote sensing

instrument specifically designed to be installed on board ULAs. Goal of the project is the

realization of a compact and inexpensive autonomous system that can be mounted on the

aircraft without the need of further modifications. The hardware layout and three

dimensional models of the various parts of the system are shown. The proposed final

configuration utilizes three cameras working in the visible spectrum two of which are

tilted in the cross-track direction of 15° in order to obtain a larger swath width on the

ground. This optimizes the elapsed mission time with respect to single camera

configuration. The third camera is equipped with a nIR filter which that allow the

extraction of the NDVI index, useful to monitor the vegetation status.

Photogrammetric or remote sensing aerial campaigns must be carefully planned

before execution so a flight planner software has been developed to support the aerial

platform. The planning software and its implementation in the Matlab environment is

presented on Chapter 5 showing already planned missions examples.

An engineering model of the FASTER system has been realized, with reduced

capabilities, in order to start a complete test campaign on the instrument. The FASTER

EM is discussed in Chapter 6, presenting the hardware list and the management software

which has been expressly realized. Here is also shown the pilot guidance interface
