Description

The objective for PENCAP is the development of a network clock ensemble and the implementation of it on a VPX card capable of running pntOS. Prototype cards, networking methods, and an ensemble algorithm will be delivered to the Government for further development and testing. The ensemble algorithm will be designed to be robust in dynamic environments, continuously evaluating both local and remote timing references for stability, trustworthiness, and source validity. It will incorporate a weighting system, allowing references to enter and exit the ensemble without disrupting it, and will feature outlier rejection to discard invalid or unstable measurements, ensuring a consistently accurate time. To support the ensemble algorithm, a resilient network method will be designed to disseminate timing and stability information. This network will utilize various existing communication links on aircraft and can be configured in multiple ways, such as point-to-point or hub-and-spoke. The system will be designed to authenticate new nodes that join the network, ensuring the traceability and integrity of all connections. The ensemble algorithm and network method will be implemented on a prototype card. This will involve modifying a Commercial-Off-The-Shelf (COTS) 3U VPX card to function with pntOS. The design will emphasize open standards for both data and physical interfaces to simplify future integration and upgrades. The project will culminate in a series of simulated, lab, and flight tests to demonstrate the card's full capabilities. Please see attachments for additional information.
