MEMS sensor and integrated navigation technology for precision guidance

Atlantic Inertial Systems, based at Plymouth UK, has developed a range of Inertial Measurement Units (IMUs) based on vibrating structure MEMS sensors. The first generation IMU is in military service and in volume production; a second generation IMU, using digital control and providing enhanced performance and shock tolerance, is presently completing development and is in production. To provide a full navigation capability, the MEMS IMU has also been ultra tightly coupled with a suitable GPS receiver, using a highly efficient modular Kalman Filter, in a package designed for missile, munition and projectile guidance.
