On-board communication via serial link protocols such as SpaceFibre require Serializer/Deserializer (SERDES) at the physical layer, which connects two units (e.g. payload instrument, mass memory) via copper, backplanes, or optical transceivers with each other.

LEDs have been used for years within space missions and are even offered as space qualified components. Those parts are packaged in very specific cases, providing a full hermeticity at few typical wavelengths and offering limited optical power. Such LEDs are used to convey a signal from electric to optical or for optical wavelength reference.

There is increasing interest in intra-satellite optical communications, which can be higher bandwidth, lower power, and better EMC compared to the electronic counterpart. Optical transceivers are at the core of such links. for the terrestrial market where transceivers are often delivered in non-hermetic packages but for space applications, non-hermetic packaged devices present higher risk. However, if the reliability of non-hermetic packaged devices can be demonstrated it can lead to an order-of-magnitude cost reduction.

The use of COTS (Commercial Off-The-Shelf) EEE parts together with lead free solder assembly are increasing the likelihood of tin (Sn) whiskers growing and causing issues or failures of flight equipment in service. When considering the growing use of COTS, several component package types are considered most at risk of this type of issue, such as flat packs and BGAs (Ball Grid Arrays).

More and more complex functionalities are implemented in Field Programmable Gate Arrays (FPGA), which are currently procured for a very large part from U.S.A manufacturers. In order to avoid export license, to ensure European non-dependance and to have competitive products, ambitious and coordinated projects - funded by ESA, CNES and EC - have led to the development of the BRAVE family. The current family is composed of three products: ;NG-MEDIUM, NG-LARGE (both in 65nm technology) and the NG-ULTRA (using FD-SOI 28nm technology).

Currently, the space industry as a whole is facing increasing pressure from customers and environmental lobbyists and supply chains, to reduce or eliminate the use of lead. Pressure is also increasing to reduce the cost of electronic components and equipment used on launch vehicles.
 
An approach to using lead free components has been written deployed. The document No. VG-SG-1-D-0032-SYS describes steps the steps required to enable the use and delivery of equipment using a variety of components including lead free or pure tin terminations.

The number of RF connector interfaces available for use in the space industry is very limited. The most common and widespread interface is SMA. For high operating frequency, equipment manufacturers typically use the SMA2.4 (up to 50 GHz) and 1.85 (up to 65 GHz). For the last 15 years , Sub Miniature Push-on (SMP) interface has gained a lot of popularity for phased array radars because of its small size and ease of use.

In order to support the European leadership in the field of Star Trackers, the development of a new detector supporting the high-end is required.Rather than engaging the design of a new image sensor, it is considered more efficient to characterize existing developments, either to engage directly a qualification or to identify needs in terms of delta functionality or performance.State-of-the-art Star Trackers are using today 1 mega-pixel detectors. A detector with 16 mega-pixels will aim at reducing by a factor 4 the angular resolution of one pixel.

Conventional bottom-up manufacturing and test methods are associated to a substantial portion of schedule and cost in the life cycle of a space product. Innovative methods that support agile development cycles, such as Highly Accelerated Life Testing (HALT) that started in non-space space domains are now becoming applicable for space product development and are already studied by many space companies, research institutions and space agencies.
