A MEMS-based ultra-stable, sensitive accelerometer

Agiltron proposes to develop a new type of accelerometer with no moving parts to replace current gravity correction mechanizations in nuclear SSBN submarine weapon systems. We will design the accelerometer to achieve bias stability less than 0.01micro-g, scale factor stability less than 1ppb, and noise floor less than 10-9 g/sqrt(hz). Using MEMS technology, the device will be both compact and low power. Leveraging our experience in MEMS components and production of fiber optical components, fiber interferometer, sensor system fabrication, the proposed accelerometer will provide a unique solution for cost-effectiveness, high stability, and high sensitivity. In the Phase I program, the feasibility of the proposed accelerometer technology will be demonstrated through analysis and critical component fabrication.
