| Swarm CEFI High and Low Voltage Power Supply Units (ESA/COM DEV) |
|
 Swarm is the fifth ESA Earth Explorer Mission. The Swarm concept involves placing a constellation of three satellites in three different near-polar orbits to provide high-precision and high-resolution measurements of strength and direction of Earth’s magnetic field.
As subcontractor of the Canadian company COM DEV, CAEN Aerospace is taking care of the development of the Low Voltage Power Supply (LVPS) and High Voltage Power Supply (HVPS) Units for the Canadian Electric Field Instrument (C-EFI).
The goal of C-EFI instrument is to characterize the electric field about the Earth by measuring the plasma density, drift, and acceleration at high resolution.
The required Electronics have to comply with challenging constraints, such as very low electro-magnetic emissions.
CAEN Aerospace will provide the LVPS and HVPS Engineer, Qualification and Flight Models.

| Cooler Drive Electronics for Pulse Tube Cooler |
|
|
In the frame of an ESA Contract, Air Liquide selected CAEN Aerospace for the development of a Cooler Drive Electronics Laboratory Support Equipment for Air Liquide Large Pulse Tube Coolers.
Those Pulse Tubes are suitable for a wide range of demands in Space applications, from scientific and Earth observation satellites to the International Space Station.
The CDE LSE has been successfully tested at ESA/ESTEC and Air Liquide facilities. In particular, Mechanical Vibration Reduction Capability (during normal operation) and Active Dumping Feature (reduction of pistons movements during Launch Phase) have been fully verified.

PAMELA, the biggest Space Experiment studying "matter and antimatter", is sending a huge amount of data to Earth since June 2006. More than 200 electronic boards designed and implemented by CAEN Aerospace are 100% well operating, validating every day the courageous technical choices and the selection of COTS components utilized for the Flight Models.

| Aurelia provides a Development Suite for SpaceWire Remote Terminal Controller |
|
 In the framework of European Space Agency LET-SME (Leading-Edge Technology – Small & Medium-sized Enterprises) initiative, Aurelia Microelettronica awards the contract “SpaceWire Remote Terminal Controller Development Suite”.
The SpaceWire Remote Terminal Controller (SpW RTC) is a bridge between the SpW network and the CAN bus, providing a fully integrated system. This single chip (radiation tolerant 0.18 µm technology from Atmel) includes an embedded LEON2-FT SPARC V8 processor with a floating point unit and different interfaces (SpW, CAN, ADC/DAC for analogue acquisition/conversion, UARTs, timers, …).
Aurelia Microelettronica will design and produce a HW/SW SPW RTC Development Suite able to support SpW RTC future users in designing and verifying project specific on-board applications. The suite will provide software developers a proper environment to support evaluation and software development of SpW RTC designs; it will be useful to test each application integrating a SpW RTC device, making easier the integration and test phases and reducing the time-to-market.

| 1553 Transceiver for Space Applications |
|
|
In the frame of ESA "Europeanization of MIL-STD-1553B Data Bus products" initiative, EADS Astrium subcontracted Aurelia Microelettronica for the development of the monolithic 1553 transceiver fully compliant with MIL-STD-1553B in High Voltage latch-up free SOI technology.
Besides its good interfacing compatibility and noise rejecting performance, a design approach has been introduced in order to implement a device suitable for Space Environment.
The main features are:
• Radiation hardened up to 100 krad (TID)
• SEU robustness
• Latch-up immune up to 80 MeV
• Operating junction temperature range: - 55 °C to + 125 °C
