Archangel Systems, Inc. announced today that it has been awarded a Phase I Small Business Innovative Research (SBIR) contract to develop a Triaxial Accelerometer with Low Offset and Noise (TALON). This is response to a three-layered problem being experienced by the Department of Defense. First, missile propulsion and control systems now outpace the accuracy of available guidance systems. Second, smaller munitions need accelerometer and gyroscopes that offer true navigation-grade performance at tactical-grade pricing. Finally, proven and reliable supply chains and product support infrastructures must be used in order to field new technologies quickly.

As always, the problem reveals the opportunity – a low-cost, mass producible IMU with navigation-grade performance metrics could not only solve the munitions guidance issue, but it could also service the large DoD user community needing tens of thousands of units annually.

Archangel Systems, Inc. (ASI) proposes an approach coined TALON (Triaxial Accelerometer with Low Offset and Noise). TALON is a variant of ASI’s patented NGMARS concept funded through DoD SBIRS and DARPA’s NGIMG (Navigation Grade Integrated Micro Gyroscope) project. In NGMARS, a silicon rotor is force balanced electrodynamically to a null position (x, y and z) and attitude (tilt) within a cavity. Once balanced, the rotor is spun at high speed allowing roll and pitch sensing via precession forces. In this sense, NGMARS is akin to a spinning mass gyro with electrodynamic gimbals. To achieve the three axis accelerometer in TALON, the device does not need to be spun thus reducing the complexity of the electronics and algorithms.

Archangel Systems Inc. announced today it has been awarded a Phase IV contract to continue development of a Navigation Grade version of the MARS device and MARS-based Inertial Measurement Unit (IMU), under the Defense Advanced Research Project Agency (DARPA) Navigation Grade Integrated Micro-Gyroscope (NGIMG) program. 

The general purpose of this competitively awarded DARPA contract is to investigate innovative approaches that enable revolutionary advances in science, devices, or systems. The specific purpose is to develop a micro-electro-mechanical systems (MEMS) implementation of NGIMG, with the ultimate objective being the realization of tiny, low-power, rotation rate sensors capable of achieving performance commensurate with requirements for GPS-denied navigation of small platforms, including individual soldiers, unmanned (micro) air vehicles, unmanned underwater vehicles, and even tiny (e.g., insect-sized) robots. By harnessing the advantages of micro-scale miniaturization, the NGIMG program is expected to yield tiny (if not chip-scale) gyroscopes with navigation-grade performance characteristics Successful completion of this 54 month project will enable completely autonomous navigation without any reliance on GPS. Project goals are gyro bias stability of 0.1°/hr and angular random walk of 0.005°/hr in a one cubic cm package using less than 100mW of power for a six axis IMU.

NGIMG-enabled devices with characteristics similar to that listed above and achieved via low cost, batch fabrication methods are expected to enable a myriad of strategic capabilities. In particular, the sheer portability of the rotation rate sensors sought by the NGIMG program should introduce a host of new applications and deployment scenarios, including wearable inertial measurement units (IMU's) for dismounted warriors capable of GPS-denied navigation for lengthy periods; small IMU's for unmanned air and underwater vehicles, and for guidance of small, long-range munitions; and tiny IMU's for insect-like robots intended for a variety of future applications, including first warning perimeter sensing. Together with chip-scale atomic clocks (CSAC's) and location-tracking algorithms that harness additional kinetic information (e.g., biokinetic), chip-scale NGIMG's should allow man-portable dead-reckoning devices with unprecedented precision, with and without GPS. By enabling a swelling of applications, as illustrated above, miniaturization via NGIMG technology is expected to generate a need for high volume manufacturing that, together with wafer-level batch fabrication methods enabled by MEMS technology, should substantially lower the cost of miniature navigation systems, and thus, further fuel expansion of the application suite for NGIMG technology.

Archangel Systems, Inc. announced today that it has been awarded a Phase I Small Business Innovative Research (SBIR) contract to study a Radiation Hardened Location & Attitude Module (R-LAM). R-LAM 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.

This SBIR project will leverage Archangel's NG-MARS (a spinning mass IMU with navigation-grade performance), Symmetricom's Chip-Scale Atomic Clock, and NASA-Goddards' Rad-hard GPS (Navigator for the Magnetospheric Multiscale program).
