Sentinel-4 UVN

The Sentinel-4 mission is part of the COPERNICUS program, whose overall objective is to support Europe’s goals regarding sustainable development and global governance of the environment by providing timely and quality data, information, services and knowledge. Within the GMES Space Component Programme, Sentinel-4/UVN covers the needs for continuous monitoring of atmospheric composition, in particular with respect to air quality. The main data products are O3, NO2, SO2, HCHO and aerosol optical depth. SSF has been selected for development of the Application software for the whole Sentinel-4 instrument.

SSC participates in Validation testing (process to confirm that the requirements baseline functions and performances are correctly and completely implemented in the final product). The main responsibility of SSC engineer is implementation of validation tests for MIL-STD-1553B data bus (also known as the Milbus), which is the main bus for command and control of instrumentation and platform units. The tests aim to verify all aspects of the communication as Data Block Transfer Service (Distribution and Acquisition transfer), Terminal Management Service, Time Service to name a few under SSC responsibility.

The task requires deep knowledge not only of the data bus and its operation including timing, but also the Telemetry and Telecommand packet utilization (PUS) by standard ECSS-E-70-41 and interface with the Spacecraft. The Application software and the validation tests are written in programming language Ada.


We are looking for new employees to better respond to our growing customer project portfolio.
