Teledyne e2v to supply image sensors to two ESA missions

Teledyne e2v has been selected by the European Space Agency’s (ESA) industrial policy committee to supply six Copernicus Sentinel satellite missions with image sensor technology.

Teledyne e2v is a Teledyne Technologies company and part of the Teledyne Imaging Group.

The two missions, CHIME and CO2M, funded by ESA, incorporate image sensors at the heart of the instruments and will utilise Teledyne Imaging’s technology.

The Copernicus Hyperspectral Imaging Mission, CHIME, which is a unique visible to shortwave infrared spectrometer, will provide routine hyperspectral observations to support new and enhanced services for sustainable agricultural and biodiversity management, and soil property characterisation. The mission will complement Copernicus Sentinel-2, which also features a Teledyne Imaging visible sensor, for applications such as land-cover mapping. Thales Alenia Space France will lead the CHIME industrial consortium.

Commenting Dr Miles Adcock, President Space and Quantum at Teledyne e2v, said, “This is excellent news in two respects for the CHIME mission. First, the UK facility has been able to continue the long-standing supply of imaging sensor technology to the Copernicus Sentinels. Second, we have developed a UK infrared detector design and manufacturing capability that utilises the world’s best base detector substrate materials from within the Teledyne Imaging Group.”

The Copernicus Anthropogenic Carbon Dioxide Monitoring (CO2M) mission will carry a near-infrared and shortwave-infrared spectrometer to measure atmospheric carbon dioxide produced by human activity.

The mission will comprise a constellation of three spacecraft to map the emissions of carbon dioxide.

CO2M will comprise four sensor instruments, CO2I, NO2, Multi-Angle Polarimeter (MAP) and Cloud Imager (CLIM).

Teledyne Imaging will supply for the MAP instrument focal plane array (FPA) VNIR CMOS digital image sensors, from their new family called Capella (2048 x 2048 10µm pixels). Capella will also feature as the visible sensors for the CO2I and NO2 instruments.

In addition, the CLIM instrument, which relies on the Proba-V flight proven design, will utilise a Teledyne e2v VNIR CCD detector using 4 x 6000 pixels of the flight proven quadrilinear 13µm pixel device. The CO2M industrial consortium will be led by OHB-System AG.

Christophe Tatard, Vice President Business and Product Development at Teledyne e2v, said, “We have a proud heritage of supplying the Sentinels with CCD and CMOS detectors and with this extension of the programme we are very excited to now be providing a SWIR detector as well as the VNIR detectors.”
