Abstract: Stacked satellite dispensing systems are described herein. The disclosed systems have diagonal struts that stabilize satellite stacks horizontally and vertically without adding performance-reducing mass. The diagonal struts increase the number of bracing points and improve stability. The improved stability can allow for the satellite stack to be made heavier and taller, such as by having more satellites than a dispensing system with vertical struts. The diagonal struts, which provide the improved stability, can also allow for sub-stacks to be used. The sub-stacks include batches of satellites retained by the stacked satellite dispensing system. Therefore, the stacked satellite dispending system can release single satellites batches at once, rather than all the satellites at once.

Opening of the door when handle (18?) is in the locked position is prevented by a lock (24?). When converted to the electronic version, lock (24?) may remain but is capable of being unlocked by electronic actuation means (44, 78, 82).
