I have been trying to study the uncertainties associated with the orbital elements for LEO satellites determined by various Space Surveillance sensors around the globe. However, I am unable to find any documentation/study that analyses the covariance matrix associated with the published TLE, and was wondering if there is any information out there (on internet) or if the information actually is not public??

    $\begingroup$ The information actually is not public, and the vehicles' ground controllers don't use TLEs. $\endgroup$ – David Hammen Apr 13 at 13:29
