Inertial navigation sensors and system technologies are essential for modern torpedo guidance and control. The objective of this Phase I project is to design a low cost miniaturized inertial navigation system (INS) for torpedo guidance and control usingthe AGNC-developed coremicroTM IMU. This miniaturized INS is an integration of AGNC's achievements in MEMS sensors and inertial navigation system development. The application of the MEMS inertial sensors makes it possible to build a small, light,low-power, and inexpensive INS. This miniaturized INS meets the torpedo requirements by its small size, light weight, low power, and reduced cost in design and production. It can be used in torpedoes and other vehicles for guidance, attitude determinationand control. In Phase I, first, the hardware and software design of a miniaturized INS is proposed and investigated. The system design of the INS makes use of AGNC's rich experience in inertial navigation system (INS) development. Then, based onAGNC-developed technology, MEMS sensors for the miniaturized INS are designed, fabricated and integrated into the system hardware design. Next, an AGNC-developed MEMS testing and calibration system is used for design evaluation. Finally, an accuracyevaluation of the INS is performed by the way of a hardware-in-the-loop simulation.In addition to the application for torpedoes, because of its small size, low cost, and light weight, the miniaturized INS based on MEMS sensors has wide applications innavigation, control, and guidance. Examples of application areas include: miniature underwater vehicles, airborne, land vehicle navigators, micro UAVs, balloon-borne, and spaceborne vehicles, microrovers, micro tracking mechanisms, and space robots.
