7.5 OASIS: a big data platform for satellite testing

Abstract

: Airbus Defence and Space (ADS) has developed a big data platform named OASIS for Open Analytic ServIces for Satellites. Since 2020, this big data platform is in charge of real-time telemetry ingestion, analytics and visualization for a wide and global ADS Satellite Fleet Supervision. It is used all along the satellite lifetime, from design and test to in-orbit support. The supervised fleet is now composed of 55 satellites and the platform aggregates 300Gb per day. In particular, OASIS is used in the satellite Assembly Integration and Test (AIT) context, where the final satellites platforms and payloads are assembled and validated on various test benches. The OASIS capabilities to store, index, analyze test data, alert in case of anomaly during tests are vital. To cover the challenging platform requirements (scalability, high availability, data persistency, security, easy maintenance), OASIS is virtualized on a cloud environment. The architecture offers COTS as well as internal big data analysis applications. Combined with the huge telemetry data available on the platform, they intend to offer Artificial Intelligence (AI) solutions, such as automatic failure detection and predictive maintenance. They represent a huge benefit especially for testing applications, where automatization is the key of future ways of working.
