ESA Conference on Guidance, Navigation & Control; June 2008
Monday, June 2nd, 2008Tessella played an active part at the European Space Agency’s 7th conference on Guidance, Navigation and Control (GNC), which took place in Tralee, Ireland, from June 2nd to 5th 2008.
Dr David Gittins and Mr Konstantinos Siliverdis joined more than 200 GNC specialists and company officials from around the world, at this key event, which proved to be an ideal environment for the exchange of ideas.
Mr Siliverdis presented to the conference on “Rapid ADCS Design for Commercial LEO Constellations: Designing for Deadline” describing the way that Tessella’s integrated design approach allows the following issues to be addressed during the design process:
- Implementation of late design changes through increased design robustness
- Accommodation of uncertainties in hardware unit specifications through flexible and traceable design code
- Rapid re-design in response to changes in requirements by means of an efficient and fully justified design structure
The above strategy was successfully applied in the design of the Attitude Determination and Control Subsystem (ADCS) for the Globalstar Second Generation satellites, which was completed in partnership with Thales Alenia Space France, and led to the delivery of a virtually complete set of control mode algorithms in a very demanding timescale.
Tessella also presented a poster entitled “ExoMars Phase B1: Descent and Landing System Sizing and Sensitivities”, describing work performed with Deimos Space on the Mission Analysis task during ExoMars Phase B1. Tessella supported Thales Alenia Space Italy in the system-level trade-off of DLS options and consolidation of the baseline. Tessella’s tools are used to explore complex parameter spaces and sensitivities for Descent and Landing System sizing and triggering design. They are also used in the design of the thruster stage, and to perform high-fidelity simulations of performance.
An additional contribution to the papers accepted for presentation came through “The Gaia Attitude & Orbit Control System”, co-authored by James Myatt of Tessella, who is currently providing consultancy services in the design of the GAIA satellite AOCS at Astrium, UK.
Tessella also exhibited at the event, showing live software demonstrations.
