Micro-Technology for Positioning, Navigation, & Timing (micro-PNT)
Abstract
The Micro-Technology for Positioning, Navigation, & Timing (micro-PNT) program developed low-cost, size, weight, and power (CSWaP) sensors and timing devices for navigation in GPS-degraded environments. The program primarily focused on improving microelectromechanical systems (MEMS) sensors, which currently display limited performance but excellent CSWaP, and miniaturizing atomic gyroscopes and clocks, which are currently limited to laboratory experiments because of their complexity and high CSWaP. To enhance MEMS sensor performance and realize low-CSWaP atomic sensors, the program developed novel microfabrication processes, investigated new material systems, and contributed to the understanding of error sources. Innovative microfabrication techniques development allowed co-fabrication of dissimilar devices on a single chip that enabled the required clocks, gyroscopes, accelerometers, and calibration components to integrate into a small, low-power architecture. Ultimately, low-CSWaP inertial sensors and clocks enabled ubiquitous guidance and navigation on all platforms, including guided munitions, unmanned aerial vehicles (micro-UAVs), and mounted and dismounted soldiers. Service labs have been actively involved throughout the program and are facilitating transition of micro-PNT technology to Service-led programs for further development and testing.
