Unmanned Air Vehicles

Once we tried to Google “UAV” and got more than two million citations on the Internet.

Try to find the definition of unmanned aerial vehicle (UAV) and you’ll uncover a welter of choices in the literature. So, let’s just say that a UAV is an aerial vehicle capable of sustained flight without the need for a human operator onboard.

Geospatial Fusion on the Fly

(The following online version is text only. To see graphs, charts, and images, download the article pdf above.)

The development of GNSS worldwide has fundamentally changed the way many professions conduct their business.

Arguably, the profession of surveying has been most affected because surveyors, at their core, are experts at measurement. For millennia they have been the first to take advantage of any new technology that improves their ability to locate objects accurately.

Additional GPS IIR-M Satellite Launched, Quickly Begins Transmitting

The U.S. Air Force launched the fifth modernized GPS Block II Replenishment (IIR-M) satellite at 3:04 p.m. EST (20:04 UTC) December 20 from Cape Canaveral Air Force Station, Florida, (December 20) aboard a United Launch Alliance Delta II rocket. Air Force controllers set the spacecraft to "healthy" status on January 2, in what is probably a record time of 13 days.
