Títol: Integration of a Camera in the Femtosatellite Design Cycle and Assessment

Data inici oferta: 05-06-2013     Data finalització oferta: 05-02-2014


Estudis d'assignació del projecte:
    ET AERONÀUTICA 03
Tipus: Individual
 
Lloc de realització: EETAC
 
Paraules clau:
Femtosatellite, MEMS, COTS, SMD, Design cycle
 
Descripció del contingut i pla d'activitats:
A femtosatellite has a mass between 10 and 100 grams. Current
satellites are based on boxes owned by different manufacturers.
The consequence of this architecture is an increment of mass due
to structures, wiring and connectors. In this work we propose to
follow the well known "Thinking outside the box" where in our
case it will mean to design the whole satellite in a single PCB
board. Nevertheless, payloads are boxes; the client covers the
payload sensor inside a box; in contrast we propose to integrate
the payload in the satellite design cycle. Of course some design
rules must be followed by the client: Payload architecture is
based on the Surface Mounted Device (SMD) technology and the
growing nanotechnology in form of Micro-Electro-Mechanical
Systems (MEMS).

This final bachelor work (TFC) will put to the test this concept
of "Payload integration in the femtosatellite design cycle". A
SMD camera will be used in a Disaster Management (DM) mission
like the Sri Lanka tsunami impact in 2004. The satellite will
take pictures and send it back directly to the cell phone First
Responders (FR) until the help is established. At the same time,
a ground station programmed in the femtosatellite before launch
will receive the pictures in order to assess the picture quality
of the sensor.

A series of simulations and studies will be performed like:
Trajectory propagation simulation, Thermal study, Radiation
assessment, Satellites/Space Debris/Asteroids collision risk
assessment, Sensor coverage schedule study, Battery power
management study and On-board sensor data assessment.

Un femto-satélite tiene una masa de entre 10 y 100 gramos. Los
satélites comunes se basan en cajas de diferentes fabricantes. La
consecuencia de esta arquitectura es un incremento de la masa
debido a las estructuras, cableado y conectores. En este trabajo
proponemos seguir lo conocido como "Thinking outside the box", un
planteamiento diferente que se refiere a diseñar el satélite
completo en una única placa PCB. Pero al final, la carga de pago
es una caja; el cliente protege el sensor con una caja; en
contraste, nosotros proponemos integrar la carga de pago en el
ciclo de diseño del satélite. Por supuesto el cliente debe seguir
una serie de reglas: la arquitectura de la carga se basa en
tecnología Surface Mounted Device (SMD) y la creciente
nanotecnología en forma de Micro-Electro-Mechanical Systems
(MEMS).

Este trabajo de final de carrera (TFC) pondrá a prueba este
concepto de "Integración de la carga en el ciclo de diseño de un
femto-satélite". Una cámara del tipo SMD será usada en una misión
de Gestión de Catástrofes (DM) como el impacto del tsunami en Sri
Lanka en el 2004. El satélite tomará fotografías y las enviará
directamente a los teléfonos móviles de los First Responders (FR)
mientras se establece la ayuda. Al mismo tiempo, una estación de
tierra programada en el femto-satélite antes del lanzamiento
recibirá las imágenes con tal de valorar la calidad de las
imágenes del sensor.

Se realizarán una serie de simulaciones como: simulación de la
propagación de la trayectoria, estudio térmico, valoración de la
radiación, valoración del riesgo de colisión con Satélites/Basura
espacial/Asteroides, estudio de la cobertura del sensor, estudio
de la gestión de la batería y valoración de los datos del sensor.
