Vector Delay Lock Loops

GNSS receivers determine their position and clock bias by measuring the arrival times of satellite signals. Delay lock loops (DLLs) are used in traditional receivers to measure the arrival times of the signals.

Genene Fisher: Bringing Space Science Down to Earth

SIDEBAR: Genene Fisher's Compass Points

As Solar Cycle 24 rolls around toward its maximum peak next May, when a hundred or more sunspots may appear during the course of a single day, no single navigator stands at the helm to guide the hundreds of companies, research groups, users, and policy workers through the uncharted realm of spiking solar activity and its inevitable effects on GNSS.

ION's Big Year! GNSS 2012 Plus a New Pacific Rim Conference

It's a big year for the Institute of Navigation, with the venerable ION GNSS 2012 happening this September in Nashville and the new and highly anticipated Pacific PNT conference opening for the first time next April in Honolulu.

ION GNSS 2012, the granddaddy of all GNSS events, begins shortly in Music City, USA: Nashville, Tennessee.

It's scheduled during the third week of September at the downtown Nashville Convention Center, a five minute walk to the Country Music Hall of Fame and other attractions.

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?”

China Seeks to Increase BeiDou Acceptance through Standardization and Certification Effort

China will build a testing and certification network for its BeiDou satellite navigation system over the next three years as part of an effort to make the GNSS system more competitive globally.

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.
