What’s Inside Your GNSS Rover? Part 2
The second installment of a three-part look at the inner workings of high-precision surveying rovers. In Part One of this series (xyHt magazine, September 2023 issue) we focused on the antenna, amplification, and housing elements of rovers. This installment continues with channels, boards, and gates. Channels There is a lot of misunderstanding about what receiver...
What’s Inside Your GNSS Rover? Part 1
The venerable GNSS rover, has evolved into an essential part of a surveyor’s toolkit, although some mystery remains as to what that magic box does and how it does it. To demystify this, we engaged GNSS engineers to help craft this three-part “explainer” series. Part one The work of a surveyor requires a lot of...
Refining Measurement
A land surveyor unpacks the concept of accuracy “Accuracy is addictive,” my friend David Doyle once said. Doyle is a geodesist by trade. For someone in his line of work, this addiction has a rich tradition. Geodesy is the study of Earth’s shape, rotation, and gravity field. The discipline involves an eternal quest to refine...
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...
A Better GNSS?
With America, Russia, China, and the EU all now having GNSS constellations operating, what does it mean for surveyors and geospatial professionals?
GNSS
Above: The third satellite in IRNSS being tested before its successful launch. What Did Not Happen and Increases, Improvements, Innovations Sometimes the most telling precursors of the future are things that did not happen. By all accounts, 2014 should be remembered a horrible, terrible, very bad GNSS year with botched launches, toxic broadcast ephemerides, near peak...
