DARPA Announces Quantum Optical Clocks to Counter GPS Spoofing and Jamming
What Happened — DARPA unveiled the “It’s About Time” program, contracting IonQ to build tactical‑grade optical atomic clocks that can maintain precise timing for weeks to months without GPS. The clocks are intended to protect military platforms from GPS signal disruption, spoofing, and jamming.
Why It Matters for Compliance & Audit Readiness
- Timing integrity is a core component of SOC 2 Availability (CC6.1) and Security (CC7.1) criteria; loss of accurate time can cascade into service outages and data integrity issues.
- Demonstrating a resilient timing source satisfies continuous‑risk‑management requirements and provides auditable evidence of contingency planning for external dependencies.
- Verisq’s Control Mapping capability helps you align this emerging technology to existing SOC 2 controls and capture the necessary evidence for auditors.
Who Is Affected – Defense, aerospace, critical‑infrastructure operators, and any organization that relies on GPS‑derived timing for communications, navigation, or synchronization.
Recommended Actions
- Inventory all systems that depend on GPS timing and document the associated SOC 2 controls.
- Incorporate alternative timing sources (e.g., optical clocks) into your risk assessment and business‑continuity plans.
- Use a control‑mapping platform to record the mitigation, collect evidence, and keep the audit trail up‑to‑date.

Technical Notes – GPS signals are vulnerable to jamming and spoofing; optical atomic clocks operate at optical frequencies, offering holdover accuracy for weeks (airborne unit) to months (regional master). The program moves prototypes from lab to ruggedized, manufacturable form factors.
