Miniaturized Phonon Trap Timing Units for PNT of Cubesats

Active Technology Project

Project Introduction

Miniaturized Phonon Trap Timing Units for PNT of Cubesats
This project develops a fast and accurate chip-scale timing unit (clock) that can improve the quantity and quality of data transmitted from small spacecraft. Based on a new generation of phonon traps/resonators that are both passively and actively compensated, the proposed approach tackles these technical challenges by developing a chip-scale all silicon integrated clock that has orders of magnitude better frequency stability, lower acceleration sensitivity, and higher speed compared to quartz-based clock.
