FASTER

4.2 Proposed Solution

Before proceeding to the realization phase a list of requirements, arising from the

analysis of the state of the art technologies, was prepared and reported in the following

Table. Each requirement has been commented to clarify how it could be implemented in

the proposed solution.

Requirements

Comment

General Unit Requirements

RE.G.01

FASTER shall be designed to

be installed in a large variety

of ULA and GA airplanes

without any modifications to

the a/c structure and avionics.

Several adapter will be studied to make

the system compatible with different

aircrafts aerodynamic configuration.

For the purpose of this study only a

support plate for high wing aircrafts

will be developed.

Functional Requirements

RE.F.01

The system shall have the

capability to acquire high

resolution Earth images over a

large portion of the

electromagnetic spectrum

(ranging from visible to the

thermal infrared interval, 0.3

µm < λ < 14 µm)

In the FASTER system 2 colour CCD

cameras and a third camera equipped

with an nIR filter will be installed;

onboard free space will be left where a

microbolometer based TIR camera or a

compact SWIR camera added later.

RE.F.02

The system shall be able to

control and acquire more than

one sensing device using

different hardware interfaces

FASTER will use the GiGE Ethernet

interface as a standard high data rate

bus, USB will also be used to download

images while RS232, 422, 485 will be

available for camera timing and

parameters setting.

RE.F.03

Given the target area, the

system shall be able to

generate an appropriate

trajectory starting from the

departure aerodrome to last

selected waypoint

A planning tool will be developed to

rapidly generate flight trajectories given

departure and arrival airfield; the

planning tool is discussed in Chapter 5.

RE.F.04

The system shall be able to

guide the pilot through the

previously planned flight

A visual guidance interface has been

developed and presented in Section 6.6.

RE.F.05

The system shall be able to

acquire images of the selected

area only

Position information given by the GPS

receiver will be compared to the target

area coordinates and image acquisition

will be automatically started in order to

optimize data acquisition.
