Abstract:

Crucial to development of improved artillery capabilities is the fielding of tools to assist forward observers and spotter in target designation and fire direction. Notwithstanding its reliability, the conventional lensatic compass leaves much to be desired. The needle aligns itself with the local magnetic field, is attracted by nearby ferromagnetic masses, and can be tilted only a few degrees off level before significant azimuth errors arise. The lensatic compass is an analog device, thus azimuth cannot be transmitted electronically. Other pointing technologies are available but none is appropriate to the need. KVH Industries proposes to complete design of a miniature high accuracy azimuth sensor (HASS) using a strapdown triaxial digital fluxgate sensor, inclinometer and microprocessor controller. The design will demonstrate accuracy of 0.5 degrees or better after calibration over 45 degree tilt at up to 80 degrees magnetic dip angle. The focus of the Phase I effort will be to demonstrate a three-dimensional autocalibration capability. KVH offers to deliver a proof-of-principle breadboard demonstrator with PC-based three-dimensional autocalibration to the government for test and evaluation. We will also explore the feasibility of integrating the sensor element directly onto a silicon IC for miniaturization and cost reduction.
