GNSS Hotspots | August 2012

GNSS Hotspots | August 2012

1. PAPER CUTS
Washington, Oklahoma, Ohio, Georgia, Pennsylvania
√ State transportation departments in Georgia, Pennsylvania, Oklahoma, and Ohio are printing fewer state highway maps, says the Associated Press. Washington did away with them entirely. Blame it on the double whammy of public sector budget cuts and smartphone, handheld, and in-car GPS. But there are lots of holdouts. As one Indiana man said, without a paper map, “You’re beholden to the GPS lady, you know?”

Brussels View: Remembrance of Things Past

In 2003, China committed to investing €200 million (US$270 million) for the privilege of participating in the development of Europe’s Galileo program. But by 2007 it had been forced out of major decision-making because of security concerns and the collapse of the original financing plan for the program, which was to include public and private money.

Galileo SVs Test ‘Dummy’ MBOC Signal in Space

The first two Galileo in-orbit validation (IOV) satellites in space have achieved a new milestone, transmitting dummy signals in a modulation scheme designed to allow full interoperability with GPS once operational services start.

“This is an advanced modulation technique that offers robust protection against signal interference and the misleading signal reflections known as ‘multipath’,” said Marco Falcone, Head of Galileo System Services.

Single- versus Dual-Frequency Precise Point Positioning
July 5, 2012

Single- versus Dual-Frequency Precise Point Positioning

Q: What are the tradeoffs between using L1-only and L1+L2 for PPP?

A: Precise point positioning (PPP) is a technique that can compute positions with a high accuracy anywhere on the globe using a single GNSS receiver. It relies on highly accurate satellite position and clock data that can be downloaded from the International GNSS Service (IGS) or obtained in real-time from a number of service providers, using either the Internet or satellite links.
