Discover the intricacies of the Global Positioning System (GPS), a critical technology featuring 24 satellites in 6 orbital planes at 20,200 km altitude. Each plane consists of 4 satellites, collectively ensuring accurate positioning. Learn about the requirements for GPS interrupts, including the need for 1 PPS signal and the importance of WAAS for enhanced accuracy (under 3 meters). Explore how accurate positioning is vital for CIPS and DCVG surveys, and how Cathodic Technology Limited can meet your needs in North America.
