On February 28, ships navigating the Strait of Hormuz started appearing on tracking screens in places they couldn't possibly be. They appeared to be sitting on airport runways, parked on Iranian land, and clustered at nuclear power plants. More than 1,100 commercial vessels had their navigation systems scrambled in a single day following US-Israeli airstrikes on Iran, bringing a waterway that handles a fifth of the world's oil exports to a halt.

In the two weeks since the U.S. and Israel launched attacks against Iran, thousands of vessels have experienced navigation interference in the Persian Gulf. Commercial shipping through the strait, which carries roughly 20 percent of the world's oil, has nearly ground to a halt. Though rocket and drone attacks are also to blame, another major hazard is GPS spoofing—the transmission of counterfeit satellite navigation signals.

The other day we were scrolling through r/meshtastic and someone asks: "Why does my device show 10+ satellites in view while my buddy's barely sees 8?" Good question. Really good question, actually. And it's about to take us down a rabbit hole that involves atomic clocks, Cold War competition, European independence, and why your Meshtastic node cares about all of this.

The 256th Cyber Assault Division said it partnered with open-source intelligence groups to promote a network of Telegram channels and bots that offered to help the Kremlin's troops register Starlink terminals on a Ukrainian whitelist. But the channels were a ruse, and had instead been run by Ukrainian forces, who were sent location and terminal data from the soldiers, the 256th said.

Apple's satellite features were originally designed for emergencies, allowing iPhone users to contact emergency services when cellular and Wi-Fi coverage is unavailable. With recent versions of iOS, Apple has expanded those capabilities to include sending and receiving messages via satellite. This makes it possible to stay in touch with friends and family from remote locations where traditional networks do not reach, such as hiking trails, rural areas or offshore locations.

Much like the war in Ukraine, future battlefields could be drowning in electronic interference, so the US Army stress-tested new command-and-control tech against that threat. The need to maintain connections between command and deployed weapons and crews, or reestablish those links when they're lost, is shaping how soldiers train on the service's Next Generation Command and Control, a new software-driven system that's being developed for the Army.

On Thursday, Ukraine's energy minister, Denys Shmyal, warned Ukrainians to prepare for more power blackouts in the coming days as Russian air attacks continued. Prime Minister Yulia Svyrydenko said Russia had struck energy infrastructure 217 times this year. Shmyal said 200 emergency crews were working to restore power to 1,100 buildings in Kyiv alone. Russia has been targeting Ukrainian power stations, gas pipelines and power cables since mid-January, leaving hundreds of thousands of people without heat or electricity at various points.

The Defense Department didn't realize the drone was being flown by CBP when it shot it down, and had not first coordinated the use of the laser system with the US Federal Aviation Administration. The military hasn't been coordinating counter-drone measures with the FAA, and CBP drone operators didn't inform the military's laser unit that it was launching.
