Main Involvements on Earth Observation Programmes

Climate Change and Oceanography, Intelligence & Surveillance, Earth Explorers


Customers: ESA

The European Student Earth Orbiter (ESEO) is a micro-satellite mission to Low Earth Orbit. ESEO will take pictures of Earth and other celestial objects, measure radiation levels and test technologies for future education satellite missions. Industrial System Prime Contractor SITAEL S.p.A., Italy, is managing the ESEO project at system-level.

Sitael MTG


Customers: SELEX ES, ESA

MTG is the next-generation European operational geostationary meteorological satellite system – a collaborative EUMETSAT/ESA program. In particular, the Lightning Imager is one of the two imagers carried by the MTG-I imaging satellites. In the frame of a contract with SELEX ES, SITAEL is designing the Pixel Processor ASIC for the Lighting Imager Payload.

COSMO-SkyMed second-generation is a constellation of four satellites and represents the technological evolution of COSMO-SkyMed. The system “watches” the Earth day and night and under any atmospheric condition through the use of high-resolution X-band radar systems. In collaboration with SELEX ES, SITAEL is developing the Control Momentum Gyro Assembly Control Unit (CMGA CU) of the COSMO-Skymed 2nd generation satellites.

The objective of the EarthCARE mission is to make global observations of clouds, aerosols and radiation.To achieve this challenging objective the satellite carries four scientific instruments and circles Earth in a Sun-synchronous polar orbit crossing the equator in the early afternoon to optimise daylight conditions. The payload comprises two active instruments: a high-resolution atmospheric lidar and a radar, and two passive instruments: a multispectral imager and a broadband radiometer. SITAEL, as Syderal subcontractor, is developing the Mass Memory and Formatting Unit (MMFU) Power Supply Boards (PSB) for the EarthCARE Mission.

ESA Sitael Sentinel-1

Sentinel 1

Customers: AIRBUS DS, ESA

The Sentinel-1 Mission is part of the Global Monitoring for Environment and Security (GMES) Initiative whose overall objective is to support Europe’s goals regarding sustainable development and global governance of the environment by providing timely and quality data, information, services and knowledge. Sentinel-1 is an imaging radar mission at C-band aimed at providing continuity of data for user services. As subcontractor of AIRBUS DS, UK SITAEL is in charge of the DC/DC Converters development for the SAR Electronics Sub-system Transmit Gain Unit on board of the ESA Sentinel-1 satellite. As subcontractor of Thales Alenia Space Italia, SITAEL designed and produced a 16 channels High Power Command ASIC, for platform and payload control of Data Handling equipments of Sentinel-1 satellite.

Sitael Sentinel-3

Sentinel 3

Customers: Thales Alenia Space

Sentinel-3 mission falls within the Global Monitoring for Environment and Security (GMES) joint initiative of the European Community and of the European Space Agency, which foresees the production of a series of satellites (called Sentinel), developed to provide a specific contribution in the field of the Earth space observations.The Sentinel-3 programme is dedicated to operational oceanography and global land application, thanks to its payload composed of a set of optical and microwave instruments. SITAEL, as subcontractor of Thales Alenia Space France, delivered the flight model DC/DC Converters for the SRAL-C Ku (SAR Radar and ALtimeter) Radio Frequency Unity (RFU), which is one of the instrument embarked on the Sentinel-3 satellite.

Customers: COMDEV, ESA

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, SITAEL took care of the development of the Low Voltage Power Supply (LVPS) and High Voltage Power Supply (HVPS) Units for the Canadian Electric Field Instrument (CEFI). The goal of the CEFI instrument is to characterize the electric field about the Earth by measuring the plasma density, drift, and acceleration at high resolution.

Gauss UNISAT-5


Customers: G.A.U.S.S. Srl (Italy)

UNISAT-5 is the first satellite designed, built and launched by G.A.U.S.S. Srl, the company that inherits the experience gained with the UniSat program at the School of Aerospace Engineering of the University of Rome “La Sapienza”.
The launch of UniSat-5 satellite, boarded on the Dnepr rocket, took place on 21 November 2013 from Yasny cosmodrome in Russia, marking an historical event in the world of CubeSats and nanosatellites. SITAEL contributed to the mission by providing a new, cost-effective coverglass solution for a custom made solar panel (SP15).

Customers: University of Bologna (Italy)

ALMASat-1 is the first educational satellite entirely designed, manufactured and assembled in the Microsatellite Laboratory of the University of Bologna. The main objective of this first mission was to test the key performance of all microsatellite technologies developed in the lab to prepare future missions dedicated to Earth observation which requires a high 3-axis pointing accuracy. ALMASat-1 has been successfully launched in Low Earth Orbit (LEO) in February 13, 2012 onboard the VEGA Maiden Flight from Europe’s Spaceport in Kourou, French Guiana.

ALMASpace, now the microsatellite division of SITAEL, supported the mission with his team in the design and manufacturing of the systems and by providing the Adapter and Separation system.
