Symétrie chooses Renishaw encoders
Symétrie is one of the world’s leading providers of hexapod solutions for positioning and motion applications, and Renishaw’s Resolute series of absolute encoders now supports Symétrie’s Ground Integration and Calibration Support (GICS) and Zonda hexapods, designed for two types of advanced component validation testing in the manufacture of the Meteosat Third Generation (MTG) weather satellites, due for launch from 2019.
The MTG satellite series will comprise four imaging (MTG-I) and two sounding satellites (MTG-S) that will capture data from geostationary earth orbit. Both of these applications require that the actuators are individually controlled by stiff servo-loops using absolute encoder feedback.
Renishaw’s Resolute encoder system with ZeroMet (FeNi36) Rela linear scale is installed on each strut, providing high-precision metrology with near-zero thermal expansion scales, 5nm resolution, minimal noise, low cyclic error, and high translational speeds. Resolute absolute encoders ensure superior precision and stability of the GICS and Zonda hexapods and both have been certified for ISO-5 clean room applications.
