So, the first thing to do to get the Ground Station Project up and running is to take stock of everything that we have and don't have. As you find relevant items, please add them to this thread and we can identify them, their purpose, and what work needs to be done to get the parts ready to be used.
Items that we need for VHF/UHF:
- VHF LNA
- UHF LNA
- Software-Defined Radio
- Coax (Needs testing)
- Yaesu G5500 Rotator
- RF Relay Switches (Need to be acquired)
- Wall Mounts (Currently in Shack)
- Antennas (Currently in Antenna store?)
Items that we need for S-Band:
- Dish (We have one! Currently on Tillingbourne Roof)
- Rotator (Needed)
- Rotator Controller
- Kenwood TS970e Radio
- Radio Data Interface
- Radio Control Interface
If you see something post it here and if you can add more information about a thing reply to that post below.
Hey:) After our successful trip to IRW in Scotland last Summer we're kicking off our model rocketry program!
The hope is to have a big session just making rockets soon, but to do so we need to start collecting high-tech rocket parts (random cardboard tubes), so if you come across any please feel free to stash them in the corner of the Shack by the windows.
Rocketry is really fun and it'll be great to get everyone involved building stuff soon.
Ears currently has a few unused dishes lying around. One fun way to use these would be to create an EARS radio telescope. By setting up an array of small dishes we should be able to get good enough resolution to perform useful solar observations.
Initially we could start by setting up a interferometer for the monitoring of solar flares, but the ultimate aim would be to build up a high enough resolution array that we could produce radio imagery of the sun. This initial solar flare data could be fed into the Solar-Geophysical Data Report, a crowdsourced report of solar disturbances that is used by researchers (http://www.aavso.org/solar-sids).
MIT Haystack Observatory has produced a guide on making interferometers from small dishes, such as those used for satellite tv which can be found here: http://www.haystack.mit.edu/edu/undergrad/VSRT/index.html
There are quite a lot of amateur radio projects that have been set up to record data, but very few manage to convert this data into imagery. The conversion is the hard part as it is fairly processor intensive and the software for doing it is hard to find, but both of these obstacles should be able to be tackled by Ears. Radio images of the sun look cool, though, so they are definitely the data output to aim for.
After some informal discussions, it seems like a radio telescope would be something that Physics would be keen to support and the project would be a fun way to get even more random radio stuff on the University's roofs.

Paper on a spiral PocketQube antenna design.
The aim is to design a constellation of PocketQubes which will allow techniques for automated docking and formation-flying maneuvers to be demonstrated in LEO.
