Development of a nano-satellite – attitude control system

Abstract

NTU

Satellite

Research

center

initiates

the

Nano-­‐satellite

project

in

2009

to

develop

a

pico

and

Nano-­‐satellite

pair

known

as

VELOX-­‐I.

Since

then,

many

FYP,

URECA

and

DIP

students

have

been

involved

in

the

conceptualization,

design

and

prototyping

of

various

subsystems

of

the

nanosatellite.

This

project

is

part

of

the

Attitude

Determination

and

Control

System

(ADCS)

development

work.

The

project

involves

in

the

development

of

a

satellite

attitude

simulator

to

facilitate

the

development

of

the

ADCS.

The

simulator

provides

a

GUI

for

input

the

testing

specifications.

The

simulation

result

base

on

various

environment

and

system

models

will

be

displayed

in

a

3D

animation

video.

The

simulation

of

sensor

data

will

also

be

included

in

the

simulator,

and

the

result

will

be

used

to

test

the

attitude

determination

algorithm

in

the

future

ADCS

projects.

Three

substantial

attitude

control

strategies,

namely

PID,

BDOT,

and

MPC,

have

been

implemented

in

the

simulator

for

test

and

tuning.
