When a Drone Just Can’t Do It
There is a growing ebb in the tide of UAS adoption for aerial surveying, mapping, and remote sensing—finding the right balance between manned and unmanned aerial operations Unmanned aircraft systems (UAS), remotely piloted aircraft systems (RPAS), or just plain old “drones”—call them whatever you wish—have had a tremendous impact on geospatial industries. A decade ago,...
Capturing Today’s (and Tomorrow’s) Constellations
Access to all GNSS constellations provides better data, better results Enhancements made to improve the handling of satellite systems (also called constellations) and the increasing number of signals produced by these systems provide a tangible benefit to any solution that requires precise positioning. Depending on the time of day and the geographical location, some of...

Like a good surveyor, xyHt‘s March issue covers a lot of ground, bringing you stories about surveying, mapping, UAVs and, this month’s special, a look at how drones are becoming indispensable on construction sites. As always, if you don’t have a subscription to our print edition, or if someone else in the office has snaffled your...
GNSS on Bench Marks?
The GPS on Bench Marks campaign of the National Geodetic Survey is a triumph of constituency participation to improve the nation’s geodetic infrastructure. The initiative is seeing success, but also faces challenges. Multi-constellation support, and acceptance of short RTK/RTN observations, will add a productivity boost. The “GPS on Bench Marks” program of the U.S. National...
Drones in Construction
For decades the construction industry didn’t change much-and then UAV technologies came along Unmanned aerial vehicles (UAVs) or drones, as they are commonly called, are mostly electric-powered aircraft, which do not require a pilot onboard and are used to perform tasks that are either too dangerous for humans to do or too expensive with other...
Citizen Geodesist
A GPS on Bench Marks odyssey Philip Melcher of Provost & Pritchard Consulting Group in Visalia, California, has submitted GPS on Bench Marks observations on an incredible 650 Bench Marks all up and down California in the last three years. We will ask Philip a few questions to find out how he has accomplished this,...
