Successful liftoff for Earth Observation Satellite EnMAP: Bertin’s contribution to the project

The German Earth observation satellite EnMAP (Environmental Mapping and Analysis Program) was launched on April 1, 2022 aboard a SpaceX Falcon 9 rocket from the Kennedy Space Center, in Florida, USA. A couple of years ago, Bertin Technologies had participated in this program by supplying OHB System AG, the satellite’s prime manufacturer, with the FAI FAP Optical Ground Support Equipment (OGSE). Mission management is led by the Space Agency of the German Aerospace Center (DLR).

The mission of the German spaceborne imaging spectrometer will be to monitor and characterize the Earth’s environment on a global scale. EnMAP will indeed provide information about the status and evolution of terrestrial and aquatic ecosystems and their response to natural or man-made changes in the environment.

Under this program, OHB System AG awarded Bertin Technologies with the design, manufacture, test and delivery of an Optical Ground Support Equipment. This optical test bench was required for the qualification and validation of EnMAP Hyper Spectral Imager (HSI), a satellite-based hyperspectral instrument, whose performances are key to the Earth observation mission. Characterizing and calibrating such an instrument required to establish measurement setups that outperform the test object in all relevant performance aspects to achieve the required measurement accuracies.

It was also the first strong collaboration between Bertin Technologies and its subsidiary Winlight, which was acquired in 2017. Winlight was in charge of the design and manufacturing of the OGSE collimator.

Being key to the whole mission, EnMAP hyperspectral instrument puts Bertin Technologies at the heart of its success. Being awarded the responsibility of this OGSE was the first export project of the space-related activities of Bertin Technologies and subsidiary Winlight, and marked the first step of a long series.
