Design innovations towards miniaturized GPS-quality clocks

Honeywell is developing a cold atom primary standard with reduced size, weight and power in comparison to existing clocks with similar performance, showing the feasibility of achieving the long-term goal of near-GPS-quality performance in a miniaturized, fieldable package. While the physics of these clocks is well known, unique challenges with miniaturizing the components and subsystems have required new innovative solutions. The challenges, investigated solutions, and results are discussed.
