SDRC's I-DEAS Aids in Designing, Retrieving Satellite

Laben, a company of Finmeccanica, uses I-DEAS as foundation for comet-tracking satellite technology

PARIS-June 18, 2001-SDRC (Nasdaq: SDRC) today announced that Laben, a company of Finmeccanica, the largest aerospace group in Italy, uses SDRC's mechanical design automation solution I-DEAS both to design mechanical parts for satellites that track Halley's comet, and to retrieve a satellite that had lost connection with the ground during operation.

Technology based on I-DEAS enabled the ground satellite crew to access the satellite and return it. Laben has used I-DEAS for several years as part of its design and manufacture of scientific satellites and commercial telecommunications satellites.

Missions for a more and more exact "mapping" of the universe and for interplanetary space exploration, planned by ESA Scientific Executive, have had a great scientific and technological success. Among these missions, Giotto, the interplanetary probe, born to explore Halley comet, it even could be directed towards a second comet: the Grigg-Skjellerup.

For this program Laben became responsible to project and produce: OBDH-On Board Data Handling subsystem, a computerized system for scientific data acquisition, management and service, coming from onboard experiments and sent to terrestrial stations; Electronics for Johnstone experiment to measure ions energy like "tari"; PDE -subsystem's electronic unit for order control; Test equipment on earth

Only Laben's OBDH, a real "brain" installed on Giotto, allowed probe recovery after the impact with dust particles that form Halley's comet tail, causing an alignment loss between onboard aerial and terrestrial station aerials, with the consequent cancellation of signals in reception emitted by the same probe.

It has also been able to verify experiments and onboard subsystems state - at a distance of hundred of millions of kilometers from earth - suggesting to scientists the possibility of a comet mission extension (precisely, the meeting with the Grigg- Skjellerup comet).
