PLATO (PLAnetary Transits and Oscillations of stars) is a medium-class astronomical science mission belonging to ESAs Cosmic Vision Programme, which is dedicated to the detection and characterization of terrestrial exoplanets. For this purpose, PLATO will be placed in an orbit around the L2 Lagrange point of the Sun-Earth system. By performing long uninterrupted high precision observations of large samples of stars, the planetary transits can be detected and characterized by measuring and analyzing the light curves of the stars. The operational lifetime of PLATO is 6.5 years.
The contract between OHB System and ESA was signed in October 2018 and assigns to OHB System the status of Prime Contractor for the entire satellite. OHB Hellas is responsible for the requirements management in DOORS and documentation management using ECLIPSE.
