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

The Precise Ensemble Network Communications Allowing Positioning, Navigation, and Timing (PENCAP) solicitation seeks the development of a network clock ensemble system to be implemented on a modified 3U VPX commercial-off-the-shelf card running pntOS. The core objective is to create a resilient timing solution capable of operating in dynamic environments by continuously assessing the stability, trustworthiness, and validity of both local and remote timing references. The ensemble algorithm must support dynamic membership with weighted references, enabling seamless entry and exit of timing sources while rejecting outliers to ensure persistent accuracy. Complementing the algorithm is a flexible network architecture designed to disseminate timing and stability data using existing aircraft communication links, supporting configurations such as point-to-point and hub-and-spoke, with built-in authentication to secure node integration and maintain traceability. The prototype hardware must be engineered to open standards for both physical and data interfaces to facilitate future upgrades and integration, culminating in simulated, laboratory, and flight testing to validate full operational capability. The effort is structured as a Cost-Plus Fixed Fee contract with a 36-month period of performance, including a 33-month technical phase and three months reserved for final reporting. Deliverables include the prototype VPX card, the ensemble algorithm software, supporting network methods, and associated data items as defined in the Contract Data Requirements List (Attachment 5), with all hardware and software due at the end of the technical period. The solicitation requires a two-step proposal process, beginning with an Intent to Propose due 1 July 2026 and followed by a full white paper submission by 17 July 2026 via the DoD SAFE portal. Full technical and cost proposals must follow within 30 business days of a request and adhere to strict formatting rules including 10-point Arial, Times New Roman, or Calibri font, double-spaced, eight-and-a-half by eleven inch pages with one-inch margins, submitted in Microsoft Word and Excel formats respectively. Evaluation is based primarily on Technical merit, assessed through Innovation, Understanding, Technical Soundness, and Transition Potential, with Cost/Price as a substantial secondary factor focused on realism. Proposers must comply with stringent security and personnel requirements outlined in AFRLI 61-113, including submission of Senior/Key Person Profiles, a Security Program Questionnaire, and Privacy Act consent forms for all covered individuals. All personnel must complete Level I OPSEC training within 30 days of joining and undergo annual reinforcement, with
