US: Trimble acquired Terralite assets from Novariant to expand its portfolio of positioning solutions. The Terralite XPS technology is a scalable infrastructure that generates signals for real-time positioning to augment existing GPS coverage. The technology uses a network of ground-based transmitter stations to broadcast a proprietary signal to one or more mobile GPS+XPS receivers.
Bryn Fosburgh, Vice President of Trimble, said, “The solution can improve the efficiency and productivity of surface mining and other high-value site operations challenged by limited or no GPS coverage.”
GPS is a proven utility for determining positioning on the Earth’s surface. However, in certain cases it requires augmentation in areas with obstructed views of the sky, such as heavily forested areas, near high walls in open pit mines, and areas with overhead obstructions such as bridges and cranes. A variety of technologies have been implemented to augment GPS, including the development of receivers that track GPS along with additional GNSS signals, and the use of optical technology, inertial systems, cellular network assisted GPS, LAN-based positioning, laser augmented GPS and others.
Operations such as open pit mining can enhance the continuity, efficiency and productivity of GPS applications by deploying the Terralite technology to have direct control of positioning coverage in their area.
