About Us

The Business and Technology of Global
Positioning, Navigation and Timing

GPS World, the magazine, has covered the global positioning industry since 1989. Our website, gpsworld.com, began providing that same coverage in 1998, with news as it happens.

GPS World’s Navigate! newsletter first appeared in 2007, providing news conveniently delivered to your inbox.

The Digital Edition, electronically reproducing the full print issue, launched in mid-2005. Complete, convenient (browser-based, with no fat files or mandatory downloads), interactive (live, zoomable, thumbable, with immediate clickthrough to advertisers’ and other referenced sites), and portable — download it to your computer for offline reading and archiving. We introduced Apple and Android apps in 2012 and 2013, respectively.

GPS World’s market-segmented microsites are the freshest out-of-the-box tools for professionals in every tech field that uses or seeks to use global positioning, navigation, and timing. Use the tabs at the top of this page to access these highly targeted, highly accurate source materials.

We’re more than a magazine. We are an information dissemination system. And we’re not done yet.

For continuous innovation in delivery of the freshest, most comprehensive GPS/GNSS-related news to high-level corporate managers, project and engineering managers, product designers, researchers and system developers — all of whom rely on GPS World when making purchase decisions in a $5.8 billion market — just watch this space.

A Note about Our Name

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, WAAS, LAAS, NDGPS, EGNOS, private correction services, MSAS, QZSS, Beidou, 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 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.
