The Chip-Scale Atomic Clock (CSAC) effort created ultra-miniaturized, low-power, atomic time and frequency reference units. The development of CSAC enabled ultra-miniaturized and ultra-low power atomic clocks for high-security Ultra High Frequency (UHF) communication and jam-resistant GPS receivers. The use of CSAC technology can greatly improve the mobility and robustness of any military system or platform with sophisticated UHF communication and/or navigation requirements.
The Microscale Rate Integrating Gyroscope (MRIG) effort seeks to create micromachined vibratory gyroscopes that can be instrumented to directly measure the angle of rotation, extending the dynamic range and eliminating the need to integrate angular rate information. If successful, MRIG will enable high performance, low cost gyroscopes which, when integrated in Inertial Measurement Units (IMU), will be small enough for adaptation in guided munitions’ platforms, hand-held devices, and add-in portable Guidance, Navigation, and Control (GN&C) units.
Micro Inertial Navigation Technology (MINT) aims to create navigation sensors that use secondary inertial variables, such as velocity and distance, to mitigate the error growth encountered with the inertial sensor alone. The combination of micro scale navigation aiding sensors will provide navigation accuracy beyond that which can be accomplished with a traditional inertial measurement unit (IMU) – equipped with only accelerometers and gyroscopes. If successful, the MINT effort will create micro- and nano-scale low-power navigation sensors that allow long term (hours to days) of GPS denied precision navigation.
The unrelenting progression of Moore's Law has created a steady cadence to ever-smaller transistors and more powerful chips, allowing billions of transistors to be integrated on a single system-on-chip (SoC). However, engineering productivity has not kept pace with Moore's Law, leading to prohibitive increases in development costs and team sizes for leading-edge SoC design. To help manage the complexity of SoC development, design reuse in the form of Intellectual Property (IP) modules has become the primary strategy.
In modern warfare, decisions are driven by information. That information can come in the form of thousands of sensors providing information, surveillance, and reconnaissance (ISR) data; logistics/supply-chain and personnel performance measurements; or a host of other sources and formats. The ability to exploit this data to understand and predict the world around us is an asymmetric advantage for the Department of Defense (DoD).
