The world's most accurate atomic clock has passed a crucial test, confirming the precision and reliability of the timekeeping technology. Atomic clocks underpin GPS, telecommunications and fundamental physics research, so any advance in accuracy is closely watched by scientists. The result is being reported as a milestone in precision measurement, though details of the test and the team behind it are not specified.

Bill Gates appeared on CNN's Fareed Zakaria GPS to discuss what should be done about artificial intelligence right now. He set out his view on how governments and the tech industry should respond to the rapid rise of AI, adding his voice to the growing debate among business leaders and policymakers over regulation, safety and the technology's economic impact.

Galileo, the European Union's satellite navigation system and alternative to American GPS, has demonstrated its first cryptographically authenticated position fix while under active spoofing attacks. The achievement means receivers could verify that a location signal genuinely comes from the satellite constellation rather than an imposter. It matters because GPS spoofing is a growing threat to aviation, shipping and critical infrastructure, and Galileo's OSNMA-style encryption offers a defence other systems lack.

A new GPS tracking study has mapped where loggerhead turtles in Florida's Biscayne Bay face the greatest risk of being struck by boats. By following the turtles' movements, researchers identified areas where turtle activity overlaps with heavy vessel traffic, information that could guide speed limits and protections. The findings are drawing attention as boat strikes remain a leading cause of sea turtle deaths in Florida waters.
- 5Fighting GPS Spoofing With Galileo's Encrypted Signals●Defeating Satellite Spoofing With Galileo’s Encryption
Galileo, the European Union's satellite navigation system, offers an encrypted signal that can help receivers detect and defeat spoofing attacks, in which fake GPS signals trick devices into reporting false positions or times. Attention is turning to how this authentication capability can be used to protect navigation systems against growing jamming and spoofing threats.
