Student Satellite Project
SUSAT-1
1. Objectives
- Develop interest of students
in the field of space technology.
- To encourage students’
participation in the design, development and operation of small
satellites
- To link up with other
universities doing similar projects.
- To include experiments
onboard the satellite that can be used to conduct
research.
- To develop basic facilities
for satellite development in an educational environment.
- To allow students in
different fields and at different levels to have access to
satellite.
- To develop strong emphasis
on design methodologies and processes.
- To encourage new design
ideas on satellite bus, satellite payload, satellite services,
satellite networking and satellite constellations.
- To strengthen space
technology education program
2. Mission
Statement
To have a small
functional low earth orbit (LEO) satellite that can communicate with
low cost earth stations and also to have capability to take pictures
of the earth. The satellite concept will be based on design and
development of a general purpose modular satellite bus which will be
used in the future for various educational “research and development
“missions that can be realized in a small satellite.
3. Primary
Mission:
Primary mission
is design, development, testing and operation of a small satellite
in low earth orbit. Part of the primary mission is the involvement
of students in the design and development of this
project.
4. Secondary
Mission
- Communication using new modulation
schemes, error correction methods and protocols.
- To take pictures of earth.
5. Functional Requirements:
- Earth pointing capability
- Ability to communicate with earth stations.
- Ability to provide satellite health data
(telemetry).
- Ability to store and execute commands in real time or at the
assigned time (tele-command from ground).
- Ability to take decisions based on in-house health status and
conditions.
- Ability to operate in normal, extended and safe
modes.
- Store and forward capability.
- Ability to send and receive data in different modulation and
coding formats.
- Ability to store and send pictures of earth.
.
6. Satellite
Orbit
Satellite will
be launched in a low earth polar orbit.
7. Coverage
Coverage of
SUSAT-1 LEO satellite will be limited to an area under the satellite
pass, with earth pointing. Satellite will be visible to an earth
station for a limited time during pass. The satellite antenna beam
will be wide enough to cover the area under and around the
pass.
8. Lifetime and
Survivability
The satellite
mission lifetime is three years. The survivability is aimed towards
a minimum period of three years. The selection of components in
terms of reliability and redundancy will dictate the survivability
of the satellite.
9. Satellite
Access
- Satellite telemetry will be available to universities and
educational institutes.
- Satellite tele-command will be available only to limited
number of stations at different Universities.
- Educational institutes will be able to participate in
satellite payload experiments.
10. Satellite System
Design
Satellite design
will be based on the development of a satellite model. Design and
development of the following satellite bus subsystems will be
carried out as part of the project:
- Satellite structure
- Satellite power
system
- Satellite Attitude Control System
- Satellite thermal control system
- Satellite propulsion system
- Satellite Onboard Computer and Data handling
unit.
- Satellite telemetry and tele-command system.
- Satellite Antenna and RF system
- Satellite TTC station
- Satellite
earth station(s)
11. Satellite Payload
Design
- Design of satellite imaging system.
- Store and forward experiment
- Design of modulation and error correction payload.
12. Satellite Environmental
Analysis
Satellite
environmental analysis will be done to include spacecraft charging,
radiation effects, magnetic fields and other space
influences.
