Research and development programs at ATA Sensors continue to provide
improvements to current products and add new products to the lineup.

North Finding Project

Existing MHD based sensors have the ability to detect the rotation of the earth and derive true North direction to an accuracy of 3 milliradians, making precise azimuth systems possible based on the North Finder design. This product will work where magnetic interference or extreme latitudes prevent use of the magnetic compasses, and lack of motion precludes use of GPS for determining direction. Possible applications are in surveying, mining, military direction finding other applications requiring precise knowledge of true north.

MIRU-II Appendix B

Technical Abstract
The Air Force has identified the need for a small, inexpensive inertial attitude reference system that functions as a two-axis optical reference in high performance aircraft applications. Applied Technology Associates (ATA) proposes the Magnetohydrodynamic (MHD) Inertial Reference Unit (MIRU) to meet the requirement. Read more...

Inertial Angular Actuator
Imparting torque to platforms or other objects to induce or cancel motion has been a consistently challenging requirement faced by many developers. ATA has developed an inertial angular actuator that serves as it's own angular sensor! This device is extremely rugged, has kilohertz bandwidth, and uses no power and produces no disturbances when not in use (unlike conventional momentum wheels). The collocation of the sensor and actuator will enable unprecedented cancellation of
disturbances. For more information, click the link below.
