Tern AI’s low-cost GPS alternative actually works

By Lurker,
We’ve all experienced that moment of frustration when the GPS glitches and you miss an exit on the highway. The team at Tern AI, which is building a low-cost GPS alternative, says that’s because the current technology is limited by its reliance on satellite positioning.
Tern AI says it has figured out how to locate the position of a vehicle using only map information and a vehicle’s existing sensor data. The company’s pitch: It’s a cheap system that doesn’t require any additional expensive
Sony Unveils the World’s Smallest and Lightest LiDAR Depth Sensor

By Lurker,

Sony announced the AS-DT1, the world’s smallest and lightest miniature precision LiDAR depth sensor.
Measuring a mere 29 by 29 by 31 millimeters (1.14 by 1.14 by 1.22 inches) excluding protrusions, the Sony AS-DT1 LiDAR Depth Sensor relies upon sophisticated miniaturization and optical lens technologies from Sony’s machine vision industrial cameras to accurately measure distance and range. The device utilizes “Direct Time of Flight” (dToF) LiDAR technology and features a Sony Single Photon
Australia unveils jam-proof quantum tech that’s 50 times more accurate than GPS

By Lurker,
Australia’s Q-CTRL has announced the first real-world demonstration of its commercially viable quantum navigation system. The system works without Global Positioning Systems (GPS), cannot be jammed, and is already proving to be drastically more accurate than anything else.
This is a big deal as many vehicles worldwide (including planes and cars) rely heavily on GPS for navigation. However, GPS can be jammed, spoofed, or even denied, especially during military conflicts or cyberattacks.

Writing A GPS Receiver From Scratch

By Lurker,

GPS is an incredible piece of modern technology. Not only does it allow for locating objects precisely anywhere on the planet, but it also enables the turn-by-turn directions we take for granted these days — all without needing anything more than a radio receiver and some software to decode the signals constantly being sent down from space. [Chris] took that last bit bit as somewhat of a challenge and set off to write a software-defined GPS receiver from the ground up.
As GPS started as a m
