GNSS Hotspots

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?”

Interference & Jamming

The threats just keep growing to a resource that hundreds of millions of people around the world have come to rely on for a myriad purposes.

GNSS is, after all, an RF technology, vulnerable in its own way to the kind of disruptive effects that turn an AM radio into a static-ridden howl as you drive under a powerline. And the radiated energy of signals arriving with from satellite sources tens of thousands of miles away are orders of magnitude weaker than those carrying the top 40 tunes broadcast by a local station.

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.

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.

Addition of Leap Second Highlights Campaign for Its Elimination

[Updated July 4] The world’s dominant mode of timekeeping, Coordinated Universal Time (UTC), took on another leap second on Saturday, June 30 at 23:59:60 UTC.

And then the fun began: the addition caused software handling Internet services such as LinkedIn, Pinterest, Mozilla, Reddit, StumbleUpon, Yelp, FourSquare and Gawker to behave unpredictably or even crash over the weekend.
