Indoor Location: To Boldly Go . . . with or without GNSS

A cross-industry group comprising 22 companies has launched the In-Location Alliance to drive technology innovation and market adoption of high-accuracy indoor positioning solutions such as Bluetooth 4.0 and WiFi in environments where GNSS has difficulty providing service.

Established August 23, alliance members include leading handset manufacturers Nokia and Samsung as well as chipset providers, among them GNSS and mixed-signal RF companies Qualcomm, CSR (most of whose assets were recently acquired by Samsung), and Broadcom.

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?”

It’s Back: GNSS and the Right to Privacy

A new U.S. appellate court decision could bring the issue of warrantless tracking of suspects using GPS and other positioning data derived from mobile phones back before the Supreme Court.

And if the case — United States of America v. Melvin Skinner — is appealed to and accepted for review by the “Supremes,” they would probably have an opportunity to more directly address the question of whether U.S. citizens have a “reasonable expectation of privacy” in their personal location information garnered surreptitiously from GPS-enabled cell phones by police.

Interference & Jamming

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

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.
