The Copernicus Hyperspectral Imaging Mission, CHIME, 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. 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. Teledyne e2v Capella CMOS Image Sensor for Space Imaging 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.”

TI introduces the industry’s first zero- drift Hall-effect current sensors Engineers can achieve consistent, accurate measurements over time and temperature in high-voltage systems. Texas Instruments (TI) introduced the industry’s first zero-drift Hall-effect current sensors. The TMCS1100 and TMCS1101 enable the lowest drift and highest accuracy over time and temperature while providing reliable 3-kVrms isolation, which is especially important for AC or DC high-voltage systems such as industrial motor drives, solar inverters, energy-storage equipment and power supplies. For more information, see www. ti.com/TMCS1100-pr and www.ti.com/TMCS1101-pr. Ongoing demand for higher performance in industrial systems is driving the need for more precise current measurement, in addition to reliable operation, which often comes with the cost of increased board space or design complexity. TI has applied its expertise in both isolation and high-precision analog to the TMCS1100 and TMCS1101, enabling engineers to design systems that will provide consistent performance and diagnostics over a longer device lifetime, keeping its solution size compact without increasing design time. For more information on the TMCS1100 and TMCS1101, download the white paper, “Improving Performance in High-Voltage Systems with Zero-Drift Hall-Effect Current Sensing.” Improve system performance with the lowest drift over time and temperature The zero-drift architecture and real-time sensitivity compensation of the TMCS1100 and TMCS1101 enable extremely high performance, even under operational conditions such as temperature changes and equipment aging. With an industry-leading total sensitivity drift over temperature of 0.45%, maximum, which is at
