China Holds GPS Advantage Over US

The US approval of a $11 billion weapons package for Taiwan has elevated tensions across the Taiwan Strait. China’s layered approach to GPS disruption using terrestrial and fiber-based assets provides an operational tempo advantage if US forces operate under degraded or deceptive GPS conditions. The Strategic Remedy involves building a system-of-systems approach to PNT, including multi-constellation GNSS, hardened signals, and terrestrial PNT alternatives.
Key Takeaways
- The US relies heavily on GPS for positioning, navigation, and timing.
- GPS signals can be easily disrupted or denied by adversaries.
- A layered approach by China using terrestrial and fiber-based assets provides a PNT architecture that does not rely on space alone.
Strategic Implications
If Beijing escalates toward armed conflict or sustained gray zone coercion, the US dependence on GPS could undermine deterrence and complicate intervention decisions. A more resilient system-of-systems approach to PNT is needed, assuming disruption and deception as baseline conditions in a Taiwan contingency.
