Silicon-Based IMU
A silicon inertial measurement unit made
by BAe Systems has been selected for use on the South African
Army's Unmanned Aerial Observation System (UAOS) tactical aircraft.
Advanced Technologies & Engineering Co. (Pty) Ltd. of South
Africa, the aircraft developer, chose the SiIMU(TM) silicon
micro-machined electro-mechanical inertial measurement unit for the
vehicle's autopilot and strap-down inertial navigation system.
The South African Army has
selected the UAOS tactical aircraft to support artillery units in
target geo-location, fall-of-shot detection, and fire correction.
Advanced Technologies & Engineering Co. is performing aircraft
development, production, and logistic support.
"The silicon-based SiIMU sensor we will supply for this program
weighs far less, is more shock-resistant, and is less expensive
than conventional gyro systems," said Art Siegel, vice president of
Inertial Products for BAe Systems. "We are pleased to offer this
breakthrough technology in support of the vitally important and
growing UAV community."
Using the world's first silicon micro-machined ring gyroscope
technology, the SiIMU sensor is a fully compensated
6-degree-of-freedom rate and linear acceleration measurement unit.
(SiIMU technology is in production and has been selected for
various missile and projectile programs including the U.K. Navy
Seawolf, U.S. Navy Extended Range Guided Munition, U.S. Army
Advanced Precision Kill Weapon System, U.S. Navy Rolling Airframe
Missile, and the U.K. and Swedish Army's next-generation
shoulder-launched anti-tank missile, MBT-LAW.)
