Primary and Secondary Calibration on Active Layer (PASCAL)

archived

The program seeks to address challenges associated with the long-term bias and scale-factor drift of chip-scale components for Positioning, Navigation, and Timing (PNT) tasks, and is specifically interested in development of Primary and Secondary Calibration on Active Layer (PASCAL) paradigm for in-situ calibration of inertial sensors and clocks. The deliverable of this program is an integrated, ultra-miniaturized microsystem (gyroscope, accelerometer, and/or clock) with in-situ calibration capabilities strategically implemented on-chip. The effective bias and scale factor deviation of the microsystem should not exceed 1 part per million (< 1 ppm) from a nominal input/output function over a one month period. The total size of the integrated micro-system should be on the order of 30 cubic millimeters (< 30 mm3) and consume less than 50 milliwatt of power (< 50 mW). The micro-system is expected to deliver long-term stability performance in a harsh military environment, with thermal variations from -550C to +850C, vibrations from 5 Hz to 5 kHz with an average amplitude of 5 g, spin rates on the order of 300 Hz, and mechanical shock on the level of 15,000 g. Please note that this Solicitation was originally anticipated to be funded with 6.3 funds only and therefore was only posted to FedBizOpps. However, the anticipated funding type has now changed to include 6.2 funds and has thus been added to Grants.gov to allow for assistance instrument proposals/applications. See DARPA-BAA-11-43 attached.
