Growing dependence on GNSS for positioning, navigation, and timing (PNT) has raised a parallel concern about the potential risks of signal interference. The popular press has recently highlighted accounts of car thieves using GPS jammers, solar flares pumping out L-band radiation, and faulty television sets causing havoc to GPS receivers across an entire harbor.

European Union GNSS Receiver Workshop

The Geospatial Building at the University of Nottingham

A two-day workshop on GNSS receivers will take place at the Geospatial Building at the University of Nottingham Innovation Park on April 14 and 15, 2011.

In addition to talks by GNSS experts, the workshop features product demonstrations, using the test facilitiies at GRACE, the GNSS Research and Applications Center of Excellence. These include GPS and Galileo full constellation Spirent simulator, signal record and replay devices and the roof-based fixed test track designed for dynamic research and testing.

Beihang Authors Suggest TMBOC Design for China’s Compass B1 Civil Signal

Despite the fact that China’s rapidly developing global navigation satellite system now has seven spacecraft in orbit intermittently broadcasting test signals, it is the only GNSS provider that has not yet published a draft version of its interface control document (ICD), although one has reportedly been completed for more than a year.

Against that background, any new source of information about the directions of the Compass design — official, semi-official, or other — draws special attention.
