Global Navigation Satellite Systems Engineering, Policy, and Design
When Mike Horton introduced GEODNET at the ION GNSS+ conference in 2021, he recognized it was a bit of a radical idea that may be met with skepticism—but he also knew it provided a solution to a common frustration, and that’s access to low-cost GNSS corrections with centimeter level accuracy.

Santa Clara, CA-based startup Anello Photonics has announced a GNSS INS module that it says is the world’s smallest optical gyro inertial navigation system for GPS-denied navigation and localization. It is powered by the company’s optical gyroscope technology and AI-based sensor fusion engine, the combination engineered to deliver high-accuracy positioning and orientation for applications in the agriculture, construction, robotics, and autonomous vehicle space.

A: Many augmentations of GNSS satellite navigation have been developed and fielded since the GPS constellation was completed and declared fully operational in 1995. The best known of these are satellite-based and ground-based augmentation systems (SBAS and GBAS), which are public systems designed to support civil aviation.
Earlier this year, FocalPoint Positioning announced a collaboration with General Motors on the possible application of the UK GPS software company’s Supercorrelation software in future vehicles, including potential enhancements and operational expansion of its Super Cruise hands-free ADAS (advanced driving assistance system) and its upcoming higher-tech sibling Ultra Cruise.
