Owners of Fisker electric vehicles are reverse-engineering software and developing open-source tools to keep their cars running after the company went bankrupt. Fisker Ocean owners have set up a nonprofit, the Fisker Owners Association, to coordinate maintenance and repairs. They are hiring independent experts, sharing firmware and repair know-how and jointly buying parts. The group is also pressing U.S. regulators on recall obligations and discussing insurance coverage.

Warnings are growing that navigation accuracy for aircraft and drones could be disrupted as reference data used by electronic compasses ages quickly. Electronic compasses rely on Earth magnetic field models, unlike GPS, and the World Magnetic Model underpins compass functions in most devices. Earth’s magnetic field is constantly changing, shortening model validity. Concerns are also rising that an end to ESA’s Swarm mission could weaken data reliability, prompting U.S. efforts to develop near real-time magnetic sensing technology.
