FARNBOROUGH, England -- Communications technologies group Emcore has introduced a new inertial measurement and navigation unit designed for use in unmanned aerial vehicles and other applications where GPS is unavailable.
The device, called the EN-150, offers options for full navigation, or as a higher performance, smaller-sized replacement for ring laser (RLG) inertial measurement units (IMUs). Variants of the EN-150 can provide bias drift as low as 0.5 degrees per hour and an angle random walk (ARW) of 0.02 degrees/rt-hr.
Meanwhile, its internal signal processing offers two standard IMU outputs, raw acceleration and data rate at 600 Hz, and navigation data at 100Hz that includes coning and sculling compensation.
"The EN-150 is the smallest fiber optic gyro (FOG)-based IMU available and is a functional replacement for legacy products, offering significantly better performance at a much smaller size," said David Faulkner, Vice President and General Manager of Emcore's Aerospace & Defense division. "This latest addition to our navigation systems product line leverages the technology designed into our EN-300 to deliver the advantages of an FOG IMU at a lower cost than RLG units, and at a size previously achieved with MEMs-based sensors."
The EN-150 and Emcore's other line of fiber optic gyro and inertial navigation products are on display at the Farnborough International Airshow at the company's exhibit in Hall 4, Booth No. 4906.
The Farnborough International Airshow takes place July 16-22. For updates throughout the event, visit Intelligent-Aerospace.com.
