The Stars Return: Draper Patents Celestial Navigation System

Scientists at Draper Laboratory have patented a celestial navigation system called a sliced-lens star tracker, which in its early form can achieve 50-meter accuracy in GNSS-denied environments. Improvements are expected as the technology evolves. Vehicles of all kinds may be able to benefit when using this system for navigating by the stars.

Fast and Furious: The Keys to High-Dynamic Positioning

Rapidly changing motion means that every aspect of positioning must be carefully re-examined and re-evaluated to avoid costly and dangerous positioning errors. The frequent changes in heading, acceleration and deceleration inherent in rockets, missiles, jet planes, race cars and other platforms — up to 100 times per second! —  dictate a very high rate of data inputs from both inertial and GNSS sensors to capture the complex trajectory.

GNSS Foresight Heralds New Direction for Aviation, UAVs, Air Taxis and Entire PNT Industry

Spirent Communications has launched GNSS Foresight, a cloud-based solution that empowers GNSS users with advance knowledge about the strength and reliability of GNSS signals in exact locations within their operational areas. The service will have early application for aviation, unmanned and autonomous platforms, but Spirent VP Jeremy Bennington told Inside GNSS that its potential is far wider.
