2, 4, 6, 8 — Who Do We Appreciate?

January 29, 2015By

Galileo, that’s who! For dogged determination and persistent pushing-forwardness in the face of adversity, obstacles, and the occasional technical difficulty. That there may be occasional confusion, as well, or mixed messages as to just what the future may bring, is certainly understandable. In fact, it is to be expected, given the circumstances. Let’s review the math. Two Two for the... read more

Out in Front: All-Day, Everywhere for All

January 1, 2015By

We appear incompletely before you this month. A funny thing happened on the way to the presses: we discovered that we had more content than pages in which to squeeze it. “All the news that fits to print,” the motto of the New York Times, can in this instance not be ours. All the news just won’t fit! First to... read more

GNSS Frontiers: BeiDou and Ubiquitous Location

December 18, 2014By

The Stanford Center for Position, Navigation and Time conducted its eighth symposium on PNT in October. These symposia have always been a superb two (this year three) days of excellent presentations, ranging over the entire domain of PNT, including policy factors as well as technical ones. read more

As location penetrates smaller and smaller devices that lack memory and computation power, GNSS chips must reacquire the standalone capability that they shed when first going to small form factors such as phones. A new chip with a new architecture demonstrates navigation and tracking and avoids burdening its main processor with heavy software. read more

Topcon NET-G5 Tracks New L3 GLONASS Signal

November 13, 2014By

Topcon Positioning Group said that its latest GNSS reference receiver, the NET-G5, is capable of tracking a new signal from the GLONASS constellation. The GLONASS-M 55 satellite was launched in June 2014 and is equipped with the experimental payload capable of transmitting signals in the L3 frequency band. Engineers successfully tracked the signal with the NET-G5 receiver during a series of... read more
