AMBIT - Post-Auctioned SRF

The AMBIT Post Auction program, managed by the Defense Information Systems Agency (DISA), is a research, development, test, and evaluation (RDT&E) initiative funded under Program Element (PE) 0303867K. Its primary objective is to support federal agency efforts to relocate or share radio frequency spectrum, thereby making more spectrum available for commercial use. This program is closely tied to the Spectrum Relocation Fund (SRF), which was established to reimburse federal agencies for costs incurred when repurposing spectrum used for critical government missions.

The main goal of the AMBIT Post Auction line item is to facilitate the transition of federal communications systems to alternative spectrum bands or to enable spectrum sharing with commercial providers. Such transitions are technically complex and financially burdensome, often exceeding the regular budgets of federal agencies. By providing targeted funding, the program ensures that agencies can modify their systems without compromising mission effectiveness or operational security.

For Fiscal Year (FY) 2024, the program supports spectrum relocation and sharing activities. No additional funding is projected for FY 2025 or subsequent years in the current budget cycle, but the program is marked as Continuing, indicating ongoing or future planned activities. The funding is allocated to various contractors and performing activities, with award dates and specific contract details to be determined as requirements are finalized.

The JS1: AMBIT Post Auction project is the sole subcomponent under this program element. Its specific objective is to provide technical and financial support for the relocation or sharing of spectrum assets. This includes planning, engineering, and implementation activities necessary to transition federal systems to new frequency bands or to establish secure sharing protocols with commercial entities.

The project scope covers all phases of the spectrum relocation process, from initial analysis through final system modifications. Justification for the program centers on the need to balance national security and public safety requirements with the growing demand for commercial wireless services. As commercial spectrum auctions continue to expand access for private sector innovation, federal agencies must adapt their communications infrastructure to avoid interference and maintain operational capabilities.

The AMBIT Post Auction program is designed to mitigate risks associated with these transitions and to ensure compliance with federal spectrum management policies. The program does not specify a unique acquisition strategy, as funding is distributed across various support activities and contracts based on evolving technical needs. There are no other program funding summaries or acquisition remarks provided, reflecting the program's specialized and flexible approach to spectrum relocation challenges.

The schedule profile indicates that support for spectrum relocation activities began in the fourth quarter of 2021 and is planned to continue through the fourth quarter of 2028. The program's ongoing nature and flexible funding approach allow it to address emerging requirements as spectrum policy and technology evolve.
