Real-life applications • SYMÉTRIE is a major French hexapod manufacturer • SYMÉTRIE selected RESOLUTE for two hexapod solutions designed for component validation testing in the manufacture of ESA’s Meteosat Third Generation (MTG) weather satellites. “ “ We chose Renishaw’s RESOLUTE absolute encoders because of their high level of metrology performance. These absolute encoders work reliably in high vacuum conditions. Moreover, the encoder scale is made of low expansion Zero. Met material, which makes our hexapods less sensitive to temperature variations. Thermal stability was a critical requirement for these space optics projects

RESOLUTE basic principles • Readhead sensor is analogous to a digital camera • Image of scale is taken by readhead • Raw data extracted from image and processed 11001 00010 10010 Codeword look-up table. . . . • Error checking algorithm extrapolates the next reading and compares with actual for enhanced safety

RESOLUTE readhead options ØStandard • Compatible with many major industry protocols • Side-exit cable variant available • 0 °C – 80 °C ØUHV • Suitable for high-vacuum (10 -10 Torr) • 0 °C – 75 °C • Bake-out at 120 °C ØETR • Low temperature rotary applications • -40 °C – 80 °C
