The final constellation of 30 satellites will more than double the spacecraft providing the American Global Positioning System, increasing the accuracy and reliability of navigation and timing signals that can be received across the planet.
Broadcom and Qualcomm are improving the indoor positioning capabilities of their chips and improving accuracy and availability of the technology at the same time.
For example, researchers in Arizona are using real-time kinematic global positioning systems, an ultra-precise version of GPS that can measure positions with sub-inch accuracy levels, to control weeds in cotton fields with steel cultivators.
