Amateur UAV project
This
aircraft will have a certain pre-determined route, the route that is to go
a point A to a point B, C, D, etc., and return. The flight may be
autonomous or assisted manually by the pilot. Data Link to include an
air-ground communication.
For this the plane will have a navigation system that is a, GPS, a
mini-computer that will manage all operations (altitude, the route, the
motor, batteries, the level of fuel, etc.), as well as other inputs on
board.

Place:
Faro e Loulé - Portugal
Our flying field .
These photos where taken with my trainer ( 1,7 mts ) using an automatic film
camera located under the fuselage and the motor used was an O.S 46SF ( 2
stroke ) .

This
flying filed is located at the Algarve high lands just 5 kms from Loulé .
The radio used was an
Multiplex Commander MC-2010 with 5 channels for the necessary functions .

These
images are part of an aerial shooting by one of my models, on May 3, 2003, the
national meeting of Aeromodelismo in St-Margarida, conducted by FPAm .
The equipment used for issuing image / navigation, is part of a project to build
a model of piloting remote long-range (UAVs), in which I am working with the aim
of terrestrial and marine patrol .

Cockpit

With
this new equipment, and finished in a pilot phase, the pilot and remote
surveillance moves to distances much greater than allowed to human vision .
Telemetry
(to be instaled) is made through a link UHF.
For
easy transport, accommodation and use. Using the telemetry, may be
monitored in real time the state of batteries, the level of fuel, rotation
of the engine, engine temperature, humidity, air pressure, HUD,
etc., are limited only to the size model . |
|
 |
Through
a cable connecting the case, allows the viewing-by GPS navigation via PDA
with the navigation software itself, the PDA has active matrix (anti-reflex
system) which is quite useful in days of much light .
Still
unidireccional a modem that receives information from aeromodel in flight,
and transmits the geographic position, altitude, speed, heading, rate of
rise-fall, time-date, real-time sampling is also a map. The image is
visulized with OSD information and is recorded in digital format .
Save
the file of a PDA travelled routes that can be viewed using the "Google
Earth" or another and thus involve images-photos and the distances
travelled in a local map to 2 or 3 dimensions . |

directional (Patch, parabolic or yagi), for long distances .

Steering
using remote glasses of ecrans TFT . |

|

 |
This
type of steering gives an 'almost' sensation of being inside the
modelplane
and from this to another kind of feeling totally exciting, besides being
considered
as the closest to reality . |

 |
Mini-camera
transmitter that can be installed inside of small models . |
| |
 |
Cameras
in color CCD and Cmos economic and low consumption, the quality of image
(320 lines) is not bad, but it is lower compared to CCD (380, 470 and 540 lines).
However are widely used in models of the micro air vehicles type (MAV) .
|
|
| |
 |
Several
types of omnidirecionals and directional antennas are used as the desired
application . |
