Hat tip to Kevin Wamsley of Inside China Business. His recent video explaining the importance of China’s Beidou satellite navigation system provides a critical insight into the current success of Iran’s missile strikes on US and Israeli targets. It is a game changer.The
Here’s the video:
Let me summarize it. During the 12-day war in June 2025, Iranian missiles and drones struggled against sophisticated Israeli and American electronic warfare. GPS jamming and spoofing repeatedly disrupted their guidance systems, limiting their effectiveness during the intense 12-day conflict. Fast-forward to early 2026, and the battlefield dynamics had shifted dramatically. Iran’s precision strikes began threading through advanced air defenses, hitting high-value targets across the Gulf with surprising accuracy. Intelligence analysts pointed to one key factor: Iran had ditched GPS for China’s Beidou satellite navigation system.
The US unwittingly provided the spark that ignited China’s quest for the Beidou. The story begins in 1993 when a single Chinese container ship, the Yinhe, sailing to Iran, the vessel was accused by the CIA of carrying chemicals for weapons production. Middle Eastern ports, under pressure from the US, refused entry and the ship was stranded in the Indian Ocean. The US not only pressured allies but reportedly disabled the ship’s GPS access, forcing it to drop anchor for weeks. Inspections in Saudi Arabia eventually cleared the vessel, but China received no apology or compensation.
This humiliation—losing navigation mid-ocean due to reliance on a foreign-controlled system—became a pivotal lesson for Beijing. It accelerated development of an independent satellite navigation network: Beidou (BDS).
BDS-1 (2000s) provided initial regional coverage.
BDS-2 expanded capabilities.
BDS-3 (completed around 2020) transformed it into a global powerhouse with dozens of satellites, far more ground stations (especially in the Global South), and superior accuracy in many regions compared to GPS.
Today, Beidou outperforms GPS in coverage and precision across roughly 165 countries, offering a resilient alternative that cannot be unilaterally jammed or spoofed by Western powers.
After the 2025 conflict exposed vulnerabilities in GPS-dependent systems, Iran moved decisively. By late 2025 or early 2026, it integrated Beidou into its missile and drone arsenals. Reports from March 2026 already highlighted dramatic improvements: Iranian munitions evaded electronic countermeasures that had worked months earlier.
Key advantages of Beidou for Iran include:
Resistance to jamming/spoofing — Advanced frequency-hopping and anti-interference tech.
Higher accuracy — Circular error probable under 5 meters in key regions, enabling precise strikes with fewer munitions.
Real-time command — Secure messaging allows mid-flight adjustments over long distances.
This upgrade has contributed significantly to Iran’s ability to penetrate US defenses in the Gulf countries and dramatically improved Iran’s ability to strike critical targets, which has undermined confidence in US security guarantees in the Gulf.
The US decision to use GPS as a weapon in 1993 has backfired spectacularly—proof that humiliating China inspired a technological leap that now gives China and its allies a strategic advantage over the US.

It's pronounced like "bay dough". Please, for the love of God, say it that way. It really hurts my ears when you slaughter it.
Turkey : Erdogan is a rogue and dangerous leader; nobody should trust him! Regarding the F35, Interestingly the US are unable de deliver any before years, not to mention that they cannot build the radars due to their rare earth shortfalls.
Beidu: one point to clarify is the actual effect of US GPS spoofing on Iranian missiles during the 12 day 2025 war; Indeed it was then understood that Israël was close to disruption and desperately asked for US intervention…how is this to be reconciled with the GPS spoofing story ?
