    MEMS gyros for space navigation supplied by Goodrich

    Nov. 16, 2010
    CHARLOTTE, N.C., 16 Nov. 2010. Goodrich Corp. gyroscopes passed in-orbit testing on the European Space Agency's (ESA) Earth Explorer CryoSat-2 satellite during a mission to detect shifts in global ice cover. The Goodrich micro electro-mechanical system (MEMS) gyros were the smallest ever flown by ESA and were used to monitor the satellite's rate of spin. They were integrated into the SiREUS rate sensor to form Europe's first MEMS-based device to be used for space vehicle navigation.

Goodrich Corp. gyroscopes passed in-orbit testing on the European Space Agency's (ESA) Earth Explorer CryoSat-2 satellite during a mission to detect shifts in global ice cover. The Goodrich micro electro-mechanical system (MEMS) gyros were the smallest ever flown by ESA and were used to monitor the satellite's rate of spin. They were integrated into the SiREUS rate sensor to form Europe's first MEMS-based device to be used for space vehicle navigation."This sensor is based on a new concept and the flight experiment was very important for proving its feasibility." says Daniele Temperanza of ESA's Control Systems Division. "The CryoSat-2 project offered the opportunity to gain flight heritage. The satellite's precision ice measurements rely on knowing its orbital position and attitude very precisely requiring highly accurate navigation sensor performance."At the heart of the SiREUS rate sensor are three 1-square-centimeter (0.155-square-inch) MEMS gyros from Plymouth, England-based Atlantic Inertial Systems (AIS), which was acquired by Goodrich in December 2009. Running on just six watts and weighing only 750 grams (1.65-pounds), the gyros are development extensions of units already used worldwide for automotive electronic stability control. Their evolution for space was backed through ESA's Technology Programs with three England-based industrial partners: Selex Galileo, AIS, and Systems Engineering and Assessment (SEA). SiREUS is now being made available commercially through Selex Galileo.
