Satellite for ecosystem research launches into space

Satellite for ecosystem research launches into space

At the beginning of April 2022, the EnMAP mission satellite is scheduled to begin its journey into space. The satellite will provide hyperspectral images of the Earth's surface over a planned 5-year period, which contain important details for understanding ecosystems and climate change. Quantitative information about e.g. water quality of natural waters, the nutrition status of plants, and climate change impacts can be extracted from this data. The information are relevant in many areas of research, such as geology, agriculture and forestry, and hydrology. These novel Earth observation data are transmitted to the EnMAP ground segment operated by the German Aerospace Center (DLR).

The data sent from the satellite to the ground station requires extensive processing, depending on the intended use. Werum developed important components for the data management in the EnMAP ground segment. It's a distributed software system, which provides functions for controlling and processing data orders up to their delivery to end users. In the background, complex processes are conducted by automated workflows containing tasks for processing, distributing and archiving satellite data. Cross-cutting services, such as the User Management System and supporting components for the Mission Planning of the Earth Observation Center (EOC), are also integrated into these workflows.

The User Management System provides a central Identity & Access Management System (IAM) for the EOC data portal to facilitate user access to EOC services. With this system, Werum supports easy and secure access to satellite data from a wide range of missions and projects, such as the TerraSAR-X, TanDEM-X and Sentinel missions, the DESIS sensor, and soon EnMAP.
