  • Each payload comprises first attachment means attachable to the connection structure.
  • the connection structure comprises second attachment means attachable to a ground support equipment, GSE, during attachment of the multiple payload set to the dispenser body.
  • the benefit of the multiple payload set is that a large number of payloads can be mounted at the dispenser body at the same time.
  • the number of payloads can vary, but the more payloads that can be pre-connected via the connection structure the better the efficiency during assembly.
  • connection structure refers to that the structure between the payloads cannot support the multiple payload set to be lifted and maneuvered.
  • the connection structure is intended to be as light weight as possible to reduce weight but should support and collect signal cords inter-connecting the payloads and connecting the payloads to a control unit.
  • the signal cords can be wire, optical fiber or any other suitable cord or bus.
  • One reason for connecting the payloads is to enable the possibility to release the payloads in a certain order.
  • connection structure is a rail structure.

  • connection structure is designed to align the payloads according to a predetermined pattern.
  • the alignment can be done by applying the connection structure in a firm construction jig having a predetermined pattern in which the connection structure fits.
  • the payloads are then applied to the connection structure in a predetermined pattern according to the jig pattern.

  • the GSE has an elongation in the X-direction and a width in the Y-direction.
  • the GSE is designed and arranged to create a bearing structure in the X-Y plane to hinder that the multiple payload set moves in a Z direction being perpendicular to the X-Y plane.
