The Sentinel-5 Precursor satellite system (S5p) is a scientific operational Earth-Observation Satellite in the framework of the GMES (Global Monitoring for Environment and Security).

The satellite will provide atmospheric chemistry data of the troposphere, in particular of ozone, NO2, SO2, BrO, formaldehyde and aerosols. The measurements are performed in a high temporal and spatial resolution with global daily coverage.

Mission Summary TableMission Summary Table

OHB/SpaceTech defined in a Phase A/B1 system study from July 2010 to June 2011 the satellite design requirements and the accommodation details of the payload.

In this study SpaceTech signed responsible for the configuration design of the spacecraft, including the structural / thermal sizing, the dimensioning of the electrical power system, the definition of the harness and the design of the Mechanical Ground Support Equipment. In the system team with OHB, SpaceTech was responsible for the TROPOMI Payload ICD, the System Budgets and the Support Specifications for Environmental Design and Test, Alignment Requirements and EMC.

The Sentinel-5 Precursor spacecraft platform is a heritage-based single-failure-tolerant platform for Low-Earth-Orbit observation satellites with 3-axis-stabilized attitude and orbit control, high data storage capacity and X-band data downlink.

Satellite Performance SummaryS5p Satellite Performance Summary

The flight models of the Solar Array Panels (including the Deployment mechanisms) were delivered to Airbus in September 2014. The Sentinel-5 Precursor satellite has been launched on 13 October 2017 on a Rockot launch vehicle from the Cosmodrome in Plesetsk (Russia) and is now fully operational.
