Project to advance multi-GNSS development uses Spirent test systems

June 15, 2017By

Spirent Communications’ testing systems are being used by the European Union TREASURE project (Training, REsearch and Applications network to Support the Ultimate Real-time high-accuracy EGNSS). The aim of the four-year project is to provide instantaneous and high-accuracy positioning anywhere in the world, exploiting different satellite systems operating together to provide users with positional accuracy of a few centimeters. By 2020... read more

More, More, More. Accuracy, Accuracy, Accuracy.

September 2, 2015By

Reliable, consistent positioning accuracy has always driven new product development in the survey and mapping sector of the GPS/GNSS market. It’s remarkable how quickly the provided accuracy in successive new survey products over the years has increased the required accuracy from users and customers in the field, and consequently the desired accuracy in a feedback loop to the product developers.... read more

Out in Front: Addiction on the Rise

September 1, 2015By

Memory fails as to who first said “Accuracy is addictive.” Or perhaps it’s my knowledge base that is deficient. At any rate, I’ll gladly publish documented evidence from anyone who can show the earliest — print or audio — expression of that dictum. It continues to hold as true for this industry as Moore’s Law does for computer technology as a... read more

Directions 2014: Great Expectations

December 1, 2013By

By Peter O. Large, Vice President, Trimble November 29, 2013, marks the 210th anniversary of the birth of Christian Doppler. His work laid down the fundamental concepts that enabled researchers at Johns Hopkins University in the United States to make observations on the signals of Sputnik I during the International Geophysical Year of 1957. From those observations more than 60... read more

Out in Front: Welcome to Accuracy Anonymous

October 1, 2010By

Hi, my name is Alan, and I’m an accuracy addict. I got my first taste of accuracy back in 2000 when I started at GPS World, and discovered the vast range of very advanced things that people were doing with the signals of the Global Positioning System. This filled me with a great feeling of elation, expansiveness, and effectiveness. I can position anything. I can track anything. I can go anywhere, and know where I am. I can direct something else to go somewhere, and have it hit exactly on target. I can examine the minute movements of the earth, the swaying of skyscrapers, the moisture content of the atmosphere, and I can know all. I began to feel the illusion of omnipotence — of power over all. The more I found out about accuracy, the more I used it, the more addicted I became. read more

Follow up: What’s Going to Happen When GPS Accuracy is Cheap?

June 16, 2010By

I received some interesting e-mails and saw some web comments regarding my newsletter column a couple of weeks ago titled “What's Going to Happen When High-Accuracy GPS is Cheap?” The comments ranged from “I don’t believe it’s going to happen” to “We’d better adapt to the changes in technology.” read more
