This is GPS World. But the magazine has never limited itself to coverage of the U.S. Global Positioning System. We have also chronicled the development of GLONASS and Galileo; of WAAS and LAAS and NDGPS and EGNOS and private correction services; of MSAS, and QZSS, and Beidou, and GAGAN, and GRAS.

In addition to this business of global navigation satellite systems, we examine many fellow travelers, the technologies that GPS has taken along for the ride in its efforts to achieve greater accuracy, availability, integrity, and robustness. We're talking inertial sensors, LORAN-C, lasers, LIDAR, electronic compasses, cellular signal positioning, video signal positioning, odometers, wheel speed sensors, ultra wideband, RFID, Bluetooth, DSRC, and more.

These draw our interest because GPS — as a concept now, not just a physical manifestation— has spread relentlessly, inexorably across the landscape, the seas, into air space, into outer space. It has dived deep into integration with these technologies, driven by designers and engineers crafting new solutions for challenging problems in the marketplace.

Wherever it goes, we follow. That's because we all need some understanding of, or at least familiarity with, integration issues to follow GPS/GNSS in its ever-widening sphere of influence.

And because our fold increases daily. GPS World readers now come from all high-tech sectors, as other industries realize they can benefit from high-accuracy position and timing. Thanks to our new Digital Edition, all qualified readers can now get GPS World.

We're global. We're about position. And we study systems. We're not only GPS. We're more.
