Over the next few months I’ll be updating the Tech Blog with my latest project(s) – an auto-acquire satellite antenna. Theses types of antenna seem very expensive, some in excess of $70K so I thought it would be a good project to see if I could make my own using inexpensive parts bought on-line.
The project will involve modifying an Prodelin 1.2m antenna and getting lots of different components to work together with an Arduino as the controller. The plan is to make an antenna with a one push button that is reliable, easy to use and maintain and most importantly will hit the target satellite every time and will never give up trying to find it.
The various components for the build:
- Stepper Motors (NEMA 17 & NEMA 23);
- Reading GPS Lat & Long from an external GPS antenna;
- Calculating the Polarisation, Azimuth and Elevation;
- Driving the antenna and peaking the signal:
- Box search;
- Arduino UNO R3 micro controller;
- FSK modem communicating down the receive coax to the modem/Indoor unit (perhaps);
- Xtrinsic- SENSE board;
- Limit switches;
- Physical mods to a 1.2m antenna, bearings, mounting…
Please leave a comments if there are any questions or suggestions along the way…
Wish me luck!
