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.

This Auroral Oval Monitoring (AOM) Phase A study was a reorientation after the previous Phase AB1, with a simplified payload prioritizing auroral observation and a complete redesign of the mission. The first part of the study was to update the mission architecture with an affordable, sustainable, and scalable solution resulting in a Mission Definition Review (MDR).

Focal plane assemblies for earth observation missions require cooling around 77K to 120K. The cooling is provided by radiators or redounded active coolers (e.g. Stirling or Pulse Tube Coolers). In most cases the component temperature should be stabilized in order to achieve the best performance. In addition, the detectors have to be mechanically decoupled from the rest of the structure and the cooling source to avoid thermo-elastic distortions and disturbances caused by micro vibrations e.g. from active coolers or reaction wheels.

GR740 will be soon available as space qualified microprocessor component. The performances of the GR740 (faster clock, increased MIPS/MOPS) on one side open new application scenarios for a generic On Board Computer making possible to concentrate more functionalities in a single unit, on the other side make the implementation of a flawless On Board Computer more complex.

Frequency coverage for weather and science missions in mm-wave and submm-wave radiometers is increasing and it is now possible for Omnisys to commercially offer receivers up to 1-2 THz. For frequencies exceeding 300 GHz, integrated MMIC technology is preferred as it enables performance improvements and allows for more efficient system level implementations.

Recent developments in optimisation formulation and software design have allowed multi-criteria optimisation problems to be solved in real-time on typical space-grade processors. An important potential application is slew attitude guidance in the presence of actuator limitations and star tracker or instrument exclusion zones, particularly when slew time is critical.The optimisation problem can be formulated as time, fuel or pointing error (during slew) minimisation with constraints of exclusion zones and actuator authority envelopes.

The Next Generation Microprocessor and associated SW infrastructure has been developed under various TRP activities starting in 2006. Prototypes in ST Microelectronics C65SPACE 65 nm technology have been manufactured in 2015 under the product code GR740. Prototypes and evaluation boards have been made available to end users as of Q2/2016. The GR740 has been extensively validated with functional, electrical and radiation testing throughout 2016, several anomalies have been found in the design and in the technology library.
