EMI is a serious concern for devices that are externally powered (ones that have a plug) or require signal wires that need to extend outside the device (signal wires that might attach to sensors or input/output devices). The wires that connect to power sources, or I/O points, can act as antennas that will allow EMI to be received (coupled onto them) and enter the device.

Solar Orbiter will be used to examine how the Sun creates and controls the heliosphere, the vast bubble of charged particles blown by the solar wind into the interstellar medium. The spacecraft will combine in situ and remote sensing observations to gain new information about the solar wind, the heliospheric magnetic field, solar energetic particles, transient interplanetary disturbances and the Sun’s magnetic field.

Two decades ago the development started at QinetiQ Space of the ADPMS (Advanced Data and Power Management System), the combined on-board computer and power distribution system for ESAs next generation of PROBA satellites after the successful launch of PROBA-I. Due to performance requirements, space constraints and limited availability of space grade parts at that time, several COTS component were used in the design, ranging from simple passives to SRAM and FLASH memory devices. Today, with a flight heritage of the ADPMS for a combined 16 years in orbit on Proba-II and Proba-V and with two ADPMS units flight-ready for the Proba-III formation flying mission a lot of experience and lessons learned can be shared about the use of the COTS components.
Topics addressed vary from up-screening and subsequent re-lifing challenges to
radiation testing, assembly and in flight performance.

Due to its advanced performances and cost saving, use of COTS components has been considered in the applications not only for the “NEW SPACE” satellites but also for JAXA’s spacecraft. JAXA has also been examining the possible use of COTS components and clarifying the conditions and specifications. As an outcome of the examination, we established four kinds of “Handbook of the Use of Commercial EEE Parts in Space Applications” which consists of the conditions and evaluation methods for each of four classified mission criteria for the purpose of utilizing the COTS components.
