Iran May Use China's BeiDou for Targeting

Intelligence experts suggest Iran may be utilizing China's BeiDou satellite navigation system to enhance the targeting accuracy of its missiles against Israeli and United States military assets in the Middle East. This assessment follows a noticeable improvement in Iranian missile precision since the 12-Day War with Israel in June, according to former French foreign intelligence director Alain Juillet.

Iran has launched hundreds of ballistic missiles and drones towards Israel since February 28, with some successfully striking targets despite Israeli defenses.

China officially commissioned its BeiDou Navigation Satellite System (BDS) in July 2020, developing it after the 1996 Taiwan crisis to reduce reliance on the U.S. Global Positioning System (GPS).

Background

BeiDou employs 45 satellites, significantly more than the 24 satellites used by GPS, Russia's GLONASS, or the European Union's Galileo system. This increased satellite count contributes to a reported margin of error of less than 1 meter (3.3 feet) and enhanced resistance to jamming and spoofing techniques.

The potential shift to BeiDou would allow Iran to circumvent Western jamming systems that previously disrupted its GPS-guided munitions. The system's military-tier B3A signal, with its complex frequency hopping and Navigation Message Authentication, is considered largely unjammable.

Additionally, BeiDou's short message communication tool enables in-flight redirection of missiles and drones up to 2,000 km (1,240 miles) away, offering greater operational flexibility. Iran has not confirmed or commented on the use of BeiDou.
