The objective of this SBIR Open Topic is to develop applied research towards the development of an independent, autonomous precision timing source, such as an Atomic Clock, to enable precision timing in Radio Frequency (RF) contested and congested environments.
Existing systems depend on the Global Positioning System (GPS) for positioning, navigation, and timing (PNT) services. In environments where GPS is unavailable, RF communication systems relying on precision timing are impacted. The proposed technology should address how autonomous precision timing sources can integrate into current systems and mobility platforms, including chip-scale, modular, and fixed-based timing sources. The aim is to provide a reliable autonomous precision timing source to support mission success in contested and congested environments.
