    They do station-keeping occasionally. Otherwise, orbital mechanics
    dictates that at least the outlier must cross the other paths
    twice per orbit. Probably the positions and excentricities have
    been choosen to keep the triangle as intact as possible during
    these passes.
    I made an XYZ prediction at 5 seconds interval for one orbit near
    the 00248.02127018 Epoch, using Track16; then a short program to
    find the max and min length of the triangle sides, and the latitude
    of one object in a pair:
    DC: 10 km at lat -56.1  to  39 km at lat  -4.1
    CE: 18 km at lat -14.7  to  47 km at lat -63.7
    ED: 40 km at lat -43.5  to  43 km at lat -29.3
    It would be easy to use the same data to compute the orientation
    of the triangle, and even generate three-D images, even a movie,
    but I don't have the time until work load and other projects are
