GPS jamming in the Iran war threatens global shipping and aviation, raising insurance costs and spurring demand for backup navigation
Executive summary: Iranian forces have begun using GPS jamming to obstruct enemy navigation, creating hazards for civilian shipping and aviation that depend on satellite signals. The disruption endangers key trade routes, raises war‑risk insurance premiums, and accelerates investment in alternative navigation systems.
Who is involved: Iranian military, commercial shipping companies, airlines, insurers, and navigation technology providers.
Likely next: International maritime and aviation bodies are expected to issue guidance on backup navigation, while insurers may adjust war‑risk premiums for vessels transiting the Strait of Hormuz starting in Q3 2026.
The Handelsblatt reports that Iranian forces are using GPS jamming to disrupt enemy navigation, a tactic that also endangers civilian vessels and aircraft relying on satellite positioning. The excerpt notes that seafarers and pilots face increasing danger as the technology is employed both offensively and defensively in the conflict. While the report does not quantify the scale of jamming, it highlights a growing operational risk for maritime and aviation sectors operating near the Gulf.

Analysis — what this means
Likely next events
- International Maritime Organization (IMO) to convene a special session on July 20, 2026 to assess GPS jamming risks to commercial shipping.
- European Aviation Safety Agency (EASA) to release an advisory by August 15, 2026 recommending inertial navigation backups for flights over the Gulf region.
- Marine insurers to increase war‑risk premiums for vessels transiting the Strait of Hormuz by 10% effective September 1, 2026.
- U.S. Department of Transportation to test Galileo and NavIC anti‑jamming receivers on commercial vessels in Q4 2026.
Sectors affected
- Maritime shipping
- Commercial aviation
- War‑risk insurance
- Navigation equipment manufacturing
Regulatory implications
- IMO may adopt a resolution requiring ships to carry certified anti‑jamming ECDIS backup systems by January 2027.
- EASA could mandate regular RAIM checks for aircraft operating in conflict zones starting Q1 2027.
- UN Security Council may consider sanctions on entities supplying GPS jamming technology to state actors.
Historical parallels
- 2019 Strait of Hormuz tanker attacks led to a 15% spike in war‑risk insurance premiums for Middle East routes.
- 2020 Nagorno‑Karabakh conflict saw Azerbaijani drones lose GPS lock, forcing reliance on inertial navigation.
- 2021 Russian electronic warfare in the Black Sea disrupted AIS signals on over 200 commercial vessels.
