Using HD Radio Signals for Navigation By Ananta Vidyarthi, H. Howard Fan and Stewart DeVilbiss THE YEAR WAS 1906. On Christmas Eve of that year, Canadian inventor Reginald Fessenden carried out the first amplitude modulation (AM) radio broadcast of voice and music. He used a high-speed alternator capable of rotating at up to 20,000 revolutions per minute (rpm). Connected to... read more

How the Internet of Things Now Drives Location Technology
The number of devices connecting to the Internet is growing fast. The applications running on them require location context to determine the most likely use case. These devices need continuous location — not necessarily noticed or activated by the user, but always on. The specification that becomes important is energy per day: the device must maintain its location without draining its battery — and increase location availability indoors. That creates new design requirements for hybrid capability. read more

High-Precision Receiver Design: More than Accuracy

September 2, 2015By
Hamilton-opener-O

Users in emerging applications may have different requirements from traditional high-precision users. Tracking all of the new multi-GNSS signals, and then using the large number of inputs in the positioning engine, drives the amount of processing power and memory required onboard the receiver. These in turn drive the cost, size and power consumption of the receiver in exactly the opposite direction from the expectations of customers. read more

Out in Front: Addiction on the Rise

September 1, 2015By
How accurate is good enough for the majority of your market sector? This chart show the answers from those who identified themselves as members of the survey and high-precision community. For more results from this and other sectors, see the 2015 State of the GNSS Industry Report.

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
