Existing high-resolution spectrometers have a large form factor, on the order of tens of centimeters, and require complex calibration processes to maintain accuracy.

The research introduces a novel GNSS positioning framework that leverages dual base stations and massive vehicle data to produce high-resolution atmospheric maps, enhancing the precision of GNSS.

This discovery was made thanks to high-resolution modeling of the inside of the Earth, using various types of earthquake waves to uncover the secrets of our planet's interior.
