A roundup of recent products in the GNSS and inertial positioning industry from the February 2022 issue of GPS World magazine.
The tight integration of GNSS, inertial systems, lidar sensors and 360° spherical imagery into mobile mapping systems makes 3D modeling possible and traditional GNSS or optical measurement instruments obsolete.
“Seen & Heard” is a monthly feature of GPS World magazine, traveling the world to capture interesting and […]
How Inertial Systems and GNSS Availability Will Help
Self-driving cars in urban environments can be problematic. The required multi-sensor automated systems will include GNSS, but buildings block and reflect GNSS signals, reducing system availability and accuracy. Researchers from the Illinois Institute of Technology report on how inertial navigation systems coupled with wheel-speed sensors and vehicle dynamic constraints can help.

guidance for farm vehicles must be consistently accurate at the decimeter-level, lest the machines damage the valuable crops that they are designed to service.
No matter the farm task — planting, spraying, harvesting or specialized applications such as robotic grass mowing — position accuracy matters.
Trimble’s WeedSeeker 2 technology senses whether a weed is present and signals a spray nozzle to deliver a precise amount of chemical, spraying only the weed.
