Abstract:

Applied Technology Associates (ATA) proposes to introduce a high-accuracy, inexpensive, relative position sensor (HARPS), based on shearing of EU magnetic core pieces. This new technology provides potential significant benefits for achieving a lightweight,high-precision inertial reference unit (IRU). The proposed HARP sensor will integrate technologies of low-noise differential transformer sensors, a unique shearing configuration and electronics, which can measure displacements from less than 1 nm over atotal throw of 1mm. This absolute position knowledge of an object's position with greater than 120 dB dynamic range will support nanoradian-level IRU stable platform measurement and pointing control offsets in systems with significant slewingcapabilities. A variety of Air Force, other military, NASA and commercial opportunities exist for lightweight, high-precision inertial reference systems (IRUs). New component technologies are required to gain anticipated benefits and commercialapplications. The marketing opportunity space for IRUs is primarily driven by requirements associated with advanced optical systems, with performance objectives that require precise line-of-sight (LOS) pointing and stabilization. One important and nearterm application is the Airborne Laser (ABL), particularly Block 08 upgrades. Space-based Laser (SBL) and Aerospace Relay Mirror Systems (ARMS) also require lightweight, high-precision IRUs. Precise control of fast steering mirrors is another applicationfor the proposed sensor in the cited DoD systems. Additionally, the commercial applications of a shearing displacement sensor are extensive. Current position sensors are limited in dynamic range and mounting capabilities, but are still widely used.Significant advantages, using low-cost component, in the HARP sensor, opens up opportunities in the commercial displacement sensor market.
