Research Institution
The targeting accuracy of mortar rounds is critically dependent on obtaining accurate gun barrel azimuth and elevation data to feed to the fire control system. Current barrel attitude determination is not sufficiently accurate and requires manual readouts. Creare proposes to build a sensor for the determination of azimuth and elevation using novel MEMS rate gyros and inclinometers. These highly accurate sensing elements will meet or exceed required accuracy of 1 to 3 mils. The sensor will be packaged in a rugged enclosure that will fit directly onto the barrel. We have included additional MEMS sensors to provide high rate data even after a mortar round has been fired and the barrel may have moved. Creare plans to test a benchtop design in Phase I to prove feasibility of our design and deliver complete field-ready prototypes at the end of Phase II.
