    This is a "fifth generation" photoreconnaissance satellite of a class
    which has been flying since the end of 1982.
    The more recent flights manoeuvre to ~240-300 km orbits with regular
    boosts to this orbit after orbital decay reduces altitude.  For specific
    targets the satellites might briefly manoeuvre to lower/higher orbits as
    required.   Mission duration is about a year.
