Limitation on the bandwidth of tracking through the atmosphere

In last years proceedings, the above authors reported a basic limitation on the maximum effective bandwidth when tracking through atmospheric turbulence. This limitation, called the optical frequency, was shown to be an upper limit on tilt detection. This paper will further expand on this fundamental limitation. Further testing at the MIT/Lincoln Laboratory has provided more insight into the optical frequency as well as other tracking limitations. It will be shown in this paper that scintillation appears to be dominant above the optical frequency and that by wisely selecting the bandwidth of the tracking system, one can exclude some of the noise of scintillation, while still performing the best possible tracking.
