    Thanks everyone who has given me useful pointers - as usual the answer was
    right in front of my nose! I have the SGP4/SDP4 orbital model code which of
    course recovers the semimajor axis and perigee from the input elements. I
    just change Perigee = (aodp*(1 - eo) - ae)*xkmper to (aodp*(1 + eo) -
    ae)*xkmper in order to recover the Apogee (I think!?)
    
    Thanks again,
    
    James
