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.

The European Agency for the Space Program (EUSPA) is moving forward with its rollout of the free Galileo high accuracy service (HAS). Speaking at the recent HAS Days event in Spain, EUSPA’s Carmen Aguilera said, “Galileo HAS is user driven, as is the case for all European space programs. Our goal is to make sure that the services we are delivering are tailored to meet the needs of the users and the industries that will employ them in their businesses.”
