Precise Satellite Positioning to the Nearest Micron
OHB Systems AG is constructing a new hyperspectral satellite called EnMAP for terrestrial monitoring. Five mirrors, six prisms and three cameras are being mounted in an exceedingly compact space—with frequently only fractions of a millimeter between the components. Any contact between these parts must be completely excluded during the mounting process because this would destroy the sensitive components. HEIDENHAIN LIP 581 linear encoders and the POSITIP 880 digital readout provide help.
