claims the configuration and spacing of the fittings and the length and cross section of post 22 can also be varied to accommodate specific satellite interface requirements as well as satellites of differing sizes and weights in the present invention fittings 20 are selectively configured to secure each of the plurality of satellites 18 to post 22 through a four point bolt and separation nut attachment assembly with each fitting 20 providing two points of the four point attachment as is illustrated in fig3 each fitting 20 generally includes an upper and lower planar member 40 and 42 respectively interconnected by a cylindrical web 44 an inner surface 46 of web 44 defines a passage configured to cooperate with post 22 such that inner surface 46 frictionally engages the outer surface of post 22 however those skilled in the art will appreciate that various equivalent structures for securing fittings 20 to post 22 may be used without departing from the scope of the appended claims as most clearly illustrated in fig3 each satellite 18 is shown to include a connector bolt 50 extending from a corner 48 thereof to cooperate with a separation nut assembly 52 that defines an axis 51 a connector flange 54 of separation nut assembly 52 is connectable to a fitting flange 56 interconnecting upper and lower generally planar fitting members 40 and 42 respectively each fitting flange 56 defines a connector bolt passage 60 fig2 configured to accommodate connector bolt 50 of satellite 18 it should be appreciated that fittings 20 are positioned about post 22 such that each of the four connector bolts extending from a selected one of satellite.
