A-TECH CORPORATION — Department of Defense SBIR Phase II: ATA proposes to develop, test and deliver an Optical Inertial Reference Unit (OIRU) called

Description

ATA proposes to develop, test and deliver an Optical Inertial Reference Unit (OIRU) called the MSTAR Inertial Reference Unit with DRGs (MIRU-D). The MIRU-D will incorporate four ATA ARS-14s and four Boeing MEMS DRGs on the inertially stable side of the MIRU-D. The efforts in Phase II will lay the groundwork for a unit that is both technically superior and ready for flight qualification and manufacturing, with many of the proposed components having flight heritage. The MIRU-D prototype EDU design is flexible and scalable. ATA sees potential for reducing the size of the MIRU-D mechanism to make it viable for smaller airborne platforms such as UAVs, helicopters, and tactical fighter aircraft. ATA currently produces a smaller angular rate sensor (ARS-15) that could be incorporated in the current design for significant cost savings, lower SWaP, with just a slight degradation in performance. ATA is also developing a new state-of-the-art angular rate sensor (ARS-16) that has performance better than the current ARS-14 with a size similar to the ARS-15. The ARS-16 along with the quartz DRG under development at Boeing would result in an inertial sensor suite of significant smaller size with equivalent or better performance.
