"A MEMS rotating Annular Sensor (MARS) is proposed, which senses rotation velocities and accelerations in one discrete time sensor. The sensor system is sensitive to accelerations in all three local directions x, y, and z and rotational velocities in twoaxes. Differential capacitance measured at… More

"Archangel's Air Data Attitude Heading Reference System (ADAHRS) is a solid-state unit that integrates low-cost piezoelectric MEMS gyros and accelerometers, as well as pitot and static sensing devices and a magnetometer with a local processor. Accuraciesto 1 degree RMS have been demonstrated in… More

A MEMS Rotating Annular Sensor (MARS) is proposed which senses rotation velocities and accelerations in one discrete time sensor. Differential capacitance measured at various points about the annulus permit a single MARS to measure accelerations in threedegrees of freedom and rotational velocities… More

Long range gun launched munitions developed for Naval Surface Fire Support can reach altitudes that are essentially outside the Earth's atmosphere (exoatmospheric). Once outside of the Earth's atmosphere, these projectiles are no longer subjected to atmospheric forces that can aid in the… More

Improvements to the GMD EKV on-board INS includes augmentation of the IMU with GPS aiding. Uncorrected IMU errors and vehicle attitude errors impact the total EKV pointing error. The application of emerging low-cost MEMS based sensors creates new opportunities to include GPS aiding without… More

A Fuzzy Integrated Navigation System (FINS) is proposed consisting of a GPS, Inertial Measurement Unit (IMU) and Magnetic Sensing Unit (MSU). In addition to the traditional Inertial Navigation System composed of a tightly coupled GPS-IMU, a tightly coupled MSU-IMU is added along with Fuzzy Logic… More

The work proposed here augments the increasing body of research on capturing energy from walking. It focuses on the aspects associated with converting the captured energy, in the form of physical displacement, into an electrical form. The proposed Power Generator Back Pack is based on a Vernier… More

The objective of this proposal is to develop a low cost head tracking system to monitor the orientations of an individual's head. This head tracker can be incorporated with a 3-D audio system that will provide cues to operators for increasing situational awareness. This proposed system will be based… More

The objective of this work is to develop a low cost 6 DOF body tracking system to monitor the orientations of an occupants and pedestrians as well as vehicle kinematics in vehicular impact tests. This tracker system can be standalone or part of a subsystem that can communicate with other trackers… More

XIMIR (Extreme-SWAP IMU for Missiles and Interceptors: Rad-hard), is a co-planar IMU development program that combines two navigation-grade inertial sensors being independently developed under separate funding with a novel packaging solution for shock, vibration and temperature immunity. Rad-hard… More

R-LAM (Rad-hard Location and Attitude Module), promises a new generation of both integrated navigation modules and stand-alone navigation subsystems including nav-grade IMU's, atomic-precision clocks and GPS units compliant with the Space Plug and Play Architecture (SPA) initiative. R-LAM leverages… More
