Drones swarming indoors only one highlight of AUVSI Xponential

May 17, 2017By

The Association for Unmanned Vehicle Systems International‘s annual Xponential show, which took place May 8-11 in Dallas, Texas, seemed to be at least as large as last year’s in New Orleans, Louisiana. According to the Intel CEO Brian Krzanich’s keynote address, I was among more than 7,000 attendees and 650 exhibitors. Krzanich and the Intel folks dazzled us with live indoor drone flying... read more

The sky’s alive at AUVSI’s Xponential 2017

May 12, 2017By

The Association for Unmanned Vehicle Systems International (AUVSI) Xponential 2017 show, May 8-11 in Dallas, convened a global community of commercial and defense suppliers in intelligent robotics, drones and unmanned systems. It showcases the broad forefront of autonomous vehicles generally, but in-flight in particular, and there were plenty of expanded capabilities and expanding applications on display. In one of several... read more

Surveyors’ coordinate systems for 2022 and beyond

May 3, 2017By

Time. Ask anyone what time means to them, and they will give you a different answer. Benjamin Franklin famously stated that “time is money.” Time for the surveyor can mean being out in the field retracing a boundary, drafting a plat or working with a client to help them see their goals achieved. Just like any other profession, time can... read more

New developments in UAV navigation and control

April 19, 2017By

Since we’re running essentially a navigation magazine, someone had the bright idea that maybe we could bring together the monthly review of UAS/UAV activities combined with some hint of navigation content. Seems reasonable. So delving into the academic world once more, we’ve been searching for prior papers that address novel ways for divining where a UAV might be and how it... read more

Expert Opinions: Trending technologies for UAV navigation

April 19, 2017By

Q: Where is leading technology trending for UAV navigation in complex, unstructured, and uncertain (GNSS-denied) environments in industrial applications? A: Tight integration between GNSS and inertial navigation systems (INS) can provide accurate, reliable navigation in GNSS-challenged environments, and advances in MEMS inertial technology continue to push the performance of systems that meet the size, weight and power requirements for UAV... read more

Anti-jam technology: Demystifying the CRPA

April 12, 2017By

Controlled reception pattern antennas (CRPAs, pronounced “serpers”), adaptive antennas, null-steering antennas, beamforming antennas… You’ve probably heard of at least one of those terms in any discussion around GPS anti-jam technology for defense. Because they are all terms that describe essentially the same thing: a specialized antenna that helps protect GPS receivers from interference and jamming. But what exactly are they? Where... read more
