North Korea’s GPS jamming against South Korea has collapsed this year, according to Seoul’s radio regulator, even as faults in the South’s own monitoring equipment have risen. The Central Radio Management Service confirmed the drop to NK News but would not say when the last incident occurred, citing security concerns.
The numbers are stark. As of September 14, the North’s jamming had been detected on only 10 days in 2026. That compares with 248 days in 2025 and 78 days in 2024, a fall of more than 95 percent from last year’s tempo.
Why the silence matters
GPS interference from the North has been a persistent nuisance for the South’s shipping and aviation for years, disrupting hundreds of vessels and aircraft in past campaigns. A near-total halt is a significant shift in the peninsula’s electronic warfare picture.
It is also unexplained. Pyongyang has said nothing about the change, and Seoul’s refusal to date the most recent event leaves open whether the drop reflects a policy decision, technical problems with the jamming systems, or a deliberate pivot. The regulator’s silence on timing means analysts cannot rule out a recent resumption that has simply gone unreported.
The monitoring gap
The rising faults in South Korea’s GPS monitoring network compound the uncertainty. If the equipment meant to detect interference is itself degrading, a quiet year could partly be a measurement artifact rather than a genuine stand-down.
That ambiguity is the real story for defenders. Jamming is cheap, deniable and immediate. A drop in observed attacks is not the same as a drop in capability, and any assessment that treats the two as equivalent would leave the South exposed if the campaign restarts without warning.
