*Philip Linden and Ashley Kosak | From Epoch to Ecosystem: Growing Robust Lunar PNT Networks.*
Abstract: Large-scale space capabilities rarely emerge fully formed. As standardized building blocks gain relevance through repetition, interoperability, and declining marginal cost, progress shifts from individual platform performance to accumulated flight heritage and stable interfaces. Once critical mass is reached, these architectures rapidly become default infrastructure. This pattern has appeared across space systems engineering, including CubeSats, where openness and standardization enabled a paradigm shift in satellite operations.
Epoch reframes lunar timekeeping from a specialized subsystem into shared infrastructure. By combining proven synchronization techniques, accessible hardware, and open interoperability principles, Epoch enables missions to achieve autonomy today while contributing to a resilient lunar PNT ecosystem tomorrow. Rather than relying on a single authoritative clock, Epoch builds a network of independently validated nodes whose collective resilience strengthens with each deployment.
Epoch complements efforts such as NASA LunaNet by providing a practical near term bridge. It enables autonomous operation today while remaining compatible with future shared lunar infrastructure and retaining long term value as a resilience and holdover layer.
*Philip Linden* is a space systems engineer focused on spacecraft operations, imaging systems, and onboard autonomy. At Planet, he develops automated commanding and anomaly response systems for the SkySat constellation. His background includes roles at Lockheed Martin and SpaceX spanning imaging systems, spacecraft structures, calibration, and mission operations. He is also a Research Fellow with the Open Lunar Foundation, exploring scalable and resilient precision timing systems for space missions.
*Ashley Kosak* is a technical operations and infrastructure leader with experience across aerospace, consumer electronics, and energy storage. Formerly at SpaceX and Apple, her work has focused on launch operations, propulsion reliability, manufacturing systems, validation infrastructure, and operational resilience. She is currently a Fellow with the Open Lunar Foundation, working on open and interoperable timing and coordination infrastructure for lunar and distributed space missions.

*About The Foresight Institute*
The Foresight Institute is a research organization and non-profit that supports the beneficial development of high-impact technologies. Since our founding in 1986 on a vision of guiding powerful technologies, we have continued to evolve into a many-armed organization that focuses on several fields of science and technology that are too ambitious for legacy institutions to support. From molecular nanotechnology, to brain-computer interfaces, space exploration, cryptocommerce, and AI, Foresight gathers leading minds to advance research and accelerate progress toward flourishing futures.
