“…The most welcomed power and data transmission interface is the pin-type interfaces due to its dust resistance, transmission efficiency, and function integration. 92 The SIROM-B is a typical power transmission interface which conducts a nine-pin D-sub interface connection. The ASSIST, OE-ORU, and ROSE-ORU interfaces also apply this type of interface for the power transmission.…”

Over the past decades, the development of single spacecraft for outer space exploration requires more complicated design and higher investment. From the modular design ideas of the International Space Station on-orbit service, an interface design for orbital replacement unit (ORU) provides a path to develop modular spacecraft with reduction of design period and cost for satellites. A review on the ORU interfaces has been made in order to summarize the development of grabbing interfaces, mechanical docking interfaces, and multifunctional docking interfaces of ORUs in the recent 30 years. The interface parameters for both grabbing and mechanical docking processes have been summarized and compared based on the design features of ORUs. The characteristics of mechanical, power, data, thermal flow, and fluid interfaces of the ORUs are discussed as well. The future direction, challenges, and applications of the ORU interfaces have been investigated, and advanced technologies such as target recognition and precise measurement and control are suggested for the development of autonomous and intelligent interfaces. This work provides fundamental knowledge and guidelines for the development of ORU interfaces.

Space system design rules and manufacturing processes may sometimes lead to the use of floating conductors in internal subsystems. This configuration promotes charge accumulation and increases the risk of electrostatic discharges. This paper presents an experimental and numerical study on this issue. We have selected and tested a Sub-D connector that is susceptible to internal charging because it may contain ungrounded conductors. We assessed its charging behavior and the risk of discharges induced by floating pins. For this purpose, the connector is tested in different configurations. It is irradiated using mono-energetic electron beams, carried out in the GEODUR irradiation facility installed at ONERA (Toulouse, France). Electric currents and potentials induced within the irradiated connector have been measured and correlated with simulation performed with SPIS-IC code. Experiments revealed that the connector's charging behavior is directly influenced by energy of the involved particles. The sample could present fast charging kinetics after exposure for a few hours at relatively low electron fluxes. Electrostatic discharges, intense enough to damage sensitive electronic components, have also been observed. We have shown that the discharge risk is mainly related to the connector wiring.
