Positioning Infrastructure


A variety of methods have evolved to determine geographic positions on the earth for navigation, orientation, and control systems. Many different surveying tools and devices have emerged to make measurements in real-time using lasers, radio waves, optical devices, etc. Perhaps the most significant positioning technology of our time is based on the Global Positioning System, or GPS. The combination of GPS satellites and ground-based, solid state receiver electronics enable accurate, real-time measurements virtually anywhere on earth. GPS has proven to be a valuable and cost-effective asset for anyone needing geographic position information.

View-of-Sky: A Requirement for GPS

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 near high walls in open pit mines and areas with overhead obstructions. A variety of technologies have been implemented to augment GPS, including the development of receivers that track GPS along with additional GNSS signals such as GLONASS, Galileo, and Compass, and the use of Terralite XPS technology, optical technology, inertial systems, laser augmented GPS and others . Open pit mining operations 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.

Trimble's Solution

Trimble Terralite XPS technology can be used to form a "positioning infrastructure". Based on a wealth of experience with pseudolites, Trimble has adapted this technology to be deployed for high-value, precision enabled operations in surface (or "open pit") mines, urban canyons, and other areas with significant overhead obstructions. By establishing their own positioning infrastructure, owners can enhance the efficiency and productivity of their operations by having direct control of position coverage, 24/7.
