> "With little funding or congressional support, I proposed integrating China’s BeiDou satellite navigation system as a backup for civilian use to enhance redundancy and interoperability across the private sector, including in critical infrastructure. The proposal raised eyebrows. Over time, however, it gained traction with key stakeholders across the executive branch, including the National Security Council, the National Space Council, the Cybersecurity and Infrastructure Security Agency, and the Department of Transportation. Unfortunately, the administration’s time in office ended before I could bring the proposal to a broader group of agencies for review and approval. A new opportunity may now be on the horizon."
