COVER STORY
GNSS Milestones
GNSS Leaders Review 2009 and Predict 2010
From the United States, Russia, China, Europe and Japan, Inside GNSS draws on commercial and public sector leaders from all of the satellite navigation system operators to discuss the new world of four active GNSSes. Get their take on the most important events, decisions and developments of 2009—and what to expect in 2010.

FEATURE ARTICLE
THE TOP TEN
GNSS Competitiveness, Nation by Nation

Jay Gullish, Futron Corporation
More GNSS systems are live or in the pipeline than ever before. But not every space-based PNT provider can rely on supportive government policies, generous funding, abundant skilled technicians or a strong national economy. In this article, an analyst from a noted aerospace management consulting company examines the current and projected capabilities of the world’s GNSS system operators and ranks the top ten.

TECHNICAL ARTICLE
THE BURREDO
Synchronization for Direct Georeferencing on Small UAVs

John Perry, Ahmed Mohamed, Joshua Childs; University of Florida
All about the development of Burredo, an inexpensive, lightweight sub-microsecond timing system that synchronizes the position and attitude of a remote sensing system at the moment of exposure.

The Longer the Better: Coherent Integration Time in GNSS Receivers
Thomas Pany, IFEN GmbH
Data bit transitions, oscillator jitter, and user dynamics prevent coherent integration time in a GNSS receiver for more than a few dozen milliseconds. But increasing this to several seconds would help solve three problems in a degraded signal environment: multipath mitigation, enhancing the cross-correlation properties of the PRN codes to alleviate the near-far problem (or intra-system interference), and reducing the squaring loss to provide more accurate pseudorange/Doppler measurements. A recently developed GPS/Galileo receiver prototype addresses these very issues.
