Expert Opinions: Integrity in the vehicle environment

January 23, 2017By

Q: Why do we need to take integrity seriously in the vehicle environment?   A: Since the 1980s, surveyors and geodesists have used GPS for high-accuracy positioning. We take for granted centimeter- and even millimeter-level accuracy positioning capability that is faster, more reliable, at a lower cost and with fewer constraints than ever before. However, the demand for “trustworthy positioning”... read more

Drone developments: Avionics, fuel cells and swarms

January 18, 2017By

The first year I was at the Association for Unmanned Vehicle Systems International (AUVSI) convention in 2012 (well before it became Xponential) in Las Vegas, Nevada, I spent a lot of time looking for any exhibitors who were thinking of business in commercial unmanned aerial systems (UAS). At that time, the U.S. military had not yet suffered the major budget... read more

January issue: All the news that fits…

January 15, 2017By

We have a finite number of pages to bring you each month, one might say a tightly controlled number. That number has never easily accommodated the quantity of fresh, relevant GNSS and PNT news and technical material that emerges each month. The pace of your developments is too fast with which to keep up! This month, a case in point.... read more

Geolocation and the surveyor: Looking back to the future

January 5, 2017By

The surveyor has been known throughout history for many things: part expert measurer, part historian, part lawyer and part geographer. These attributes have led the surveyor to become a trusted member of the mapping community, on both the public, and private sides. Through the use of technology and associated mapping knowledge, the surveyor has provided the base layer for almost... read more

GNSS CEOs see bright future, alternative PNT promises well

December 28, 2016By

It has been a good year for all global navigation satellite systems (GNSS), as the chief executives of each system testify here. Alternative positioning, navigation and timing (PNT) also thrives. In this roundup of the latest highlights from the past year and forecasts for the future, 2017 augurs very well indeed! Let’s look at the newest alternative-PNT offerings first, followed... read more

New defense signals offered, new defense editor sought

Two important new signals — or rather, one signal and one group of signals — became available for military users worldwide last week. Satelles made an exciting announcement of what amounts to a new dimension in satnav: a whole new constellation in low-Earth orbit, bringing global coverage and most critically, a signal strength hitherto unknown to GNSS users. The satellite... read more

When inertial can help with GNSS solutions

December 14, 2016By

A number of organizations are focusing on how inertial can help GNSS receivers to provide more stable, reliable position outputs when signals are hard to receive. Papers presented in September at the ION GNSS+ 2016 conference in Portland, Oregon, demonstrate that there is indeed a lot of focused effort in this area. The conference showcased several integrated inertial GNSS solutions from a... read more
