Many civilian aircraft and helicopters now use MEMS technology in their primary
inertial guidance systems, said Sean Neylon, CEO of Colibrys SA of Neuchatel, Switzerland, which supplies MEMS for the aerospace industry.
Their work includes a thought-provoking analysis of the successes and failures of not only GPS but also laser, electro-optical, and
inertial guidance techniques for precision weapons.
Later in the program, he said, the two competitors will develop a new seeker, which is more expensive but more precise technology than
inertial guidance. This technology is needed for the SDB to be able to chase mobile targets.
The Gal (GPS-Aided Lizard) adds satellite and
inertial guidance.
The missile which has the features to deceive any anti-ballistic missiles uses advanced
inertial guidance system with manoeuvring trajectory and reaches the targets with a few metres' accuracy.
The missile uses jam-proof
inertial guidance, and current mobile launchers are believed to have GPS launch-reference positioning.
The sensors, which are part of an
inertial guidance unit, include odometers to measure linear displacement and gyroscopes to measure rotation (or yaw) rate.
up to 18 km) relies on its own
inertial guidance system.
The AFDS was originally fitted with only
inertial guidance, but (as in the case of the DWS24/39 sold to Sweden) is flow also available with GPS.
The land target attack BGM-109C/D Tomahawk utilizes terrain comparison-aided
inertial guidance with digital scene-matching terminal guidance.
