S-band Antenna on the Green Building

Prof. Sara Seager is leading an effort to renovate the old S-band weather radar on the roof of the tall Green Building (54) at MIT, which we also support. This group met in the spring to talk about options for improving its mechanical operation and modifying its RF front end to be compatible with the desired frequencies. It would be great if the dish could support tracking and communication of university-class CubeSats. Some of the ideas for it include implementation of a software-defined radio system. The MIT amateur radio club is also helping to guide the effort, as they have been the most frequent users of the equipment recently. There is already an MIT-affiliated set of three equatorial S-band ground stations (the Open System of Agile Ground Stations, or OSAGS) and it would be great to have another station at higher latitudes to improve coverage.
