I was wondering how successfully folks are using tle's for tracking,
given that fresh elsets are only issued (to my knowledge), when the
accumulated along track error is something like 5 kilometres (a
significant fraction of a degree for a Mir pass at the zenith).

Do you rely on a large field of view or use the position calculated from
the tle as the basis for tracking having manually corrected the offset
early on in the pass (or at intervals during the pass)? Or are fresh
tle's (few hours old) good enough?
