    In SkyMap, you can set your elevation to -6370000 (or -6370k), latitude to
    90 or -90, and longitude to 0, to get Earth centered predictions, then zoom
    in on each satellite to read its longitude and latitude. (This way you can
    also get ground track plots)
    But that hardly helps photography - just as well run predictions for your
    site, and read coordinates, or view star field around the interesting sats!
