GPS is almost 40 years old. While mass consumer use of GPS began only within the past decade or so, GPS was "born" during the Labor Day weekend of 1973, when about a dozen military officers and industry analysts under the leadership of Brad Parkinson met to consolidate the concept for a single satellite-based navigation system for the U.S. Department of Defense. Their proposal for NAVSTAR GPS was approved on December 22, 1973. The first satellite to be launched under the GPS program, on July 14, 1974, was the Naval Research Laboratory’s Navigation Technology Satellite (NTS) 1. read more

“B1 ICD was released while Regional System is officially operational, will affect domestic BDS receiver industry? Pros? Cons?”

By Greg Turetzky, Intel I recently attended the Fourth China Satellite Navigation Conference (CSNC, held May 15–17 in Wuhan, China), as an invited speaker and panelist. I had attended the third CSNC last year in Guangzho, and as expected this year’s was a little bigger and a little better. The Chinese GNSS industry is growing quickly, as evidenced by the... read more

Beidou to Ensure Information Security

May 24, 2013By

The chief designer of the BeiDou Navigation Satellite System said China will advocate the use of the system, which will be compatible with new devices, “so that Beidou can function properly and independently even if something goes wrong with the GPS.” Sun Jiadong, chief designer of BDS and an academician of the Chinese Academy of Sciences, made his comments in... read more

Expert Advice: The Challenge of BeiDou

May 1, 2013By

By Mark Sampson, Racelogic GNSS is changing. The days of only American GPS satellites providing signals to the civilian population are gone as new constellations are launched. GLONASS was a slow starter, but is now well established, and its signal architecture is now commonly implemented in manufacturers’ chipsets. Galileo is still very much in test phase with global coverage planned... read more

Out in Front: The System, Simulated

May 1, 2013By

Wealth, breadth, and depth. That’s what this issue brings you, in signal simulation- and testing-related content. Unfortunately, the wealth on offer has to large extent elbowed out our two news sections, The Business and The System. The former is given short shrift in this issue and the latter even shorter herewith, in pithy precis with website shortcuts. And our apologies.... read more
