Neural Net for Satellite Control
- Hi group,
I hope all your projects are going well. Here is an update on
Our primary project is the IVCOMM satellite prototypes, for
communications relay from space probes to our earth station. The
prototypes are using the CubeSat format, a standard format for
student and amateur built pico-satellites. The requirements for the
relay satellites, which have been dubbed Parrot Class satellites,
1. two way communications between the ground and orbit
telemetry, comm. relay, command & control
2. two way communications between two spacecraft
forward data (realtime relay), telemetry
3. maintain orbit, control orientation
4. take and xmit pictures ,Wide Angle and Telephoto,
Normal Light and Infrared photos
5. LIDAR (Light Detecting and Ranging ) to detect
close and approaching objects.
We have chosen a different method for control of the satellites.
These units will be built as space birds, with a basic pattern
recognition neural network for operator authorization and manual
control functions, and a hardwired decision network for application
control. and Normal operations mode will follow this logic:
1. Maintain orientation to receive signal from space probe,
received signals are rebroadcast automatically to other relay
satellites and to ground, also operate Lidar based proximity sensor
to detect close and approaching objects,
2. If Prox. Alarm, adjust attitude and/or use thrusters to
change orbit and avoid collision, then return to mode 1
3. If auth. command for photo app, change orientation to
aim camera at target and xmit photos to ground station for default
time, or until stop signal received, then return to mode 1.
4. If low battery signal received, orient for best sunlight
on solar panels, then place all modules in sleep mode until
batteries are recharged, then return to normal operations mode 1.
This design allows for autonomous operations of the satellites, and
makes little or no use of microprocessors or memory. Final plans
and a working model of the Parrot class satellite will be completed
over the next 2 months. Any thougts in the design of the neural
nets for this project will be greatly appreciated!
Our second working project is the balloon lifted aerosat, named
Asgard. Asgard will be used to demonstrate satellite applications,
command and control during the IV Space Academy events. This unit
will be based on the CANSAT. The aerosats will be created in
cooperation with JP Aerospace, who will also provide a high altitude
testing platform for the IVCOMM test model.
Anyone interested in participating in either of these projects can
