The System: IRNSS Signal Close up

September 1, 2013By and

IRNSS Signal Close up By Richard Langley, Steffen Thoelert, and Michael Meurer The spectrum of signals from IRNSS-1A, the first satellite in the Indian Regional Navigation Satellite System, as recorded by German Aerospace Center researchers in late July, appears to be consistent with a combination of BPSK(1) and BOC(5,2) modulation. Figure 1 shows that, centered at 1176.45 MHz, the signal... read more

The System: IRNSS Success, GLONASS Bellyflop

August 1, 2013By

IRNSS Success The Indian Regional Navigation Satellite System (IRNSS) successfully launched its first satellite on July 1 from the Satish Dhawan Space Centre at Sriharikota spaceport on the Bay of Bengal. An Indian-built Polar Satellite Launch Vehicle PSLV-C22, XL version, carried the 1,425-kg satellite aloft. IRNSS-1A is the first of seven satellites that will make up the new constellation: four satellites... 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
