What is slotd 4.0?
Structure and lightweight construction optimized standard payload module and satellite bus connection for the transfer of technology demonstrations into Space and Industry 4.0 compliant processes, SLOTD 4.0 for short
SLOTD 4.0 concept
The modular design of the satellite in the SLOTD4.0 concept creates enormous flexibility throughout all project phases, from design, manufacture and integration to launch and operation of the system in orbit.
Furthermore, SLOTD4.0 enables a cost-effective access to space, especially for IOD/IOV payloads.
With SLOTD4.0, a new generation of small satellite systems is emerging. While in conventional systems the payload and the satellite bus, the control and supply unit of a satellite, are usually built into a monolithic structure, in SLOTD4.0 they are structurally decoupled and connected by means of a multifunctional interface.
The intelligent Space System Interface (iSSI) serves as the interface, which provides for mechanical coupling as well as for the transmission of power and data between bus and payload module.
Based on industry 4.0 processes in combination with innovation strategies, a software-supported end-to-end service is modelled and developed using guided processes.
Hereby, the product life cycle phases of the modular satellite bus are mapped from order placement and procurement to manufacturing and operation.
