Completed TRL 9 (started at 4, targeting 9)
The CubeSat Handling of Multisystem Precision Time Transfer (CHOMPTT) mission is a precision timing satellite equipped with atomic clocks synchronized with a ground clock via laser pulse. The 1U instrument contains a pair of chip-scale atomic clocks, picosecond event timers, and avalanche photo-detectors that will be integrated into a 3U CubeSat bus.
Clock synchronization between ground-to-space and space-to-space terminals is critical for future missions, especially outside GPS coverage. This technology could help enable constellations of nanosatellites to precisely correlate astronomical, heliophysical or Earth observations and to coordinate spacecraft to produce a distributed aperture.
Listed on TechPort itself — the most direct way to ask about this specific project.
This is a mature technology (TRL 9) — the realistic path in is usually NASA's Technology Transfer Program: licensing an existing NASA patent, or a Space Act Agreement to use NASA facilities/expertise directly. NASA also runs a startup licensing program with no upfront fee for companies formed to commercialize a specific NASA technology.
None of these are guaranteed paths for this specific project — TechPort itself doesn't have an "apply" button. Reaching out to the contact(s) above with a specific question is usually the fastest way to find out what's actually open.
