Low-Cost, High Anti-Jam GEU for Gun-Launched Projectiles

"This proposal is responsive to the objective of this SBIR programwhich is to "develop an inertial navigator suitable for use inguidance and control of a projectile, using commerciallyavailable low cost instruments such as micromachined siliconaccelerometers." Mayflower is proposing a program of researchand engineering development, which leads to development of low-cost, gun-hardened GEUs with anti-jam capability that are readyfor flight tests in two years. These units will use onlypresently available, low cost instruments and will provide a highdegree of protection against jamming of the GPS receiver. Ourpartner in carrying out this program is Synetics, Inc.We are considering the "Accelerometers Only" (AO) inertialnavigator concept in the Phase II program. This navigator doesnot require gyros; it uses only accelerometers which arepresently available as low-cost, gun-hard COTS devices. Althoughthis program will focus on the AO navigator, much of the resultswill be applicable to a system using a conventional INS as well.Thus a very similar system could be considered for application toERGM or other gliding projectiles.BENEFITS: The proposed R & D effort will result in the flight qualified, low-cost tactical GEU with high anti-jam capability. The proposed system will use commercial instruments, to keep the production cost low. This GEU will be suitable for use ingun-launched projectiles including ANSR and ERGM vehicles. Other pot
