Another problem with Ka-band is signal interference. Even rain weakens it. Normally in tracking if the signal drops off, it means the antenna's gone too far off target. But there are some big benefits too. So you have the ability to use higher bandwidths for your signal.
Wider bandwidth means sending more data.
So you can transmit more, and that's one of your big advantages. But TLEs can be inaccurate. For FedSat that represents an error of about 0.36 degrees. Our tests have shown that it is possible to get much larger errors. But using a TLE does put us in the ball park.
