Precise Ensemble Network Communications Allowing PNT (Positioning, Navigation, and Timing)   2

Background
The Precise Ensemble Network Communications Allowing PNT (Positioning, Navigation, and Timing) project is initiated by the Air Force Research Laboratory (AFRL) with the objective of developing a network clock ensemble. This contract aims to enhance the reliability and accuracy of timing systems in dynamic environments, which is crucial for various military applications. The goal is to deliver prototype cards and algorithms that will be further developed and tested by the Government.

Work Details
The contractor will be responsible for the following tasks:

1. Development of a network clock ensemble implemented on a VPX card capable of running pntOS.
2. Delivery of prototype cards, networking methods, and an ensemble algorithm designed to evaluate local and remote timing references for stability, trustworthiness, and source validity.
3. Incorporation of a weighting system in the ensemble algorithm to allow references to enter and exit without disruption, along with outlier rejection mechanisms for invalid measurements.
4. Design of a resilient network method for disseminating timing and stability information utilizing existing communication links on aircraft, configured in various ways (point-to-point or hub-and-spoke).
5. Authentication of new nodes joining the network to ensure traceability and integrity.
6. Modification of a Commercial-Off-The-Shelf (COTS) 3U VPX card to function with pntOS while emphasizing open standards for data and physical interfaces.
7. Conducting simulated, lab, and flight tests to demonstrate the card's capabilities.

Period of Performance
The contract will be performed over a specified period that includes development phases leading up to testing milestones.

Place of Performance
The work will primarily take place at Wright Patterson AFB, OH.

Bidder Requirements
Bidders must demonstrate capability in developing complex electronic systems involving network communications and timing algorithms. Specific qualifications may include experience with VPX card modifications, familiarity with pntOS, and proven track record in conducting flight tests and simulations.
