Descrizione del progetto
La creazione della futura unità di misura inerziale europea
Mentre le tecnologie spaziali fanno passi avanti in tutto il mondo, le missioni europee dipendono dall’unità di misura inerziale americana (IMU). Non esistono alternative in Europa per un’IMU coerente ed economica. Il progetto EURISA, finanziato dall’UE, proporrà un modello ingegneristico di IMU europea economica e performante, basata su giroscopi a fibre ottiche e accelerometri al quarzo per le future missioni spaziali. Il progetto si baserà sugli attuali sviluppi avanzati dei suoi quattro partner (Airbus Defence & Space, ETH Zurich, DLR Bremen e iXblue), sviluppando e assemblando ulteriormente i componenti per produrre la futura IMU europea. EURISA testerà il modello in ambienti spaziali, misurerà e convaliderà le sue prestazioni inerziali e consegnerà algoritmi di ibridazione elaborati per fornire prestazioni di navigazione ottimali.
Obiettivo
EURISA aims at ensuring long term availability of a European cost-effective and performant IMU based on fiber-optic gyroscopes and quartz accelerometers for the future space missions. As of today, all European missions depend on American IMU, mainly Northrop Grumman LN200S, with no alternative in Europe for compact and cost-effective IMU.
The main goal of the project is to deliver an engineering model of this IMU at TRL equal or higher than 6. The engineering model will be tested in space environments and its inertial performances will be measured and validated. On top of that, the project will also deliver crafted hybridization algorithms to provide the best possible navigation performances
EURISA relies on 4 actors of the European space ecosystem: Airbus Defence & Space, ETH Zurich, DLR Bremen and iXblue. They have all the required competencies and know-hows to make a success out of this project: space electronics, inertial sensors, knowledge on the space mission requirements, hybridization algorithms, space environment and also manufacturing and quality.
In practice, the project will be built on current developments of the partners that have already reached TRL 4 and above: compact fiber-optics gyroscopes, quartz accelerometer, space electronic boards based on COTS and hybridization algorithms. In the frame of EURISA, these different elements will be further developed or adapted, then qualified and finally assembled together to make the future European IMU.
By using current developments and many synergies together with the use of COTS, we ensure a cost-effective product and a safe path toward a TRL 6 maturity.
