Taking Turns at the Fiscal Cliff

The GPS program has taken a fiscal hit that will delay critical plans to begin multi-satellite launches and could ultimately hamper the Air Force’s ability to keep the constellation at its current level of service.

The shortfall is just one of the challenges facing the program over the next four months as the current six-month budget extension winds down, the government’s ability to borrow runs out, and, barring a fast political deal, the onerous budget cuts set up under sequestration kick in.

Galileo Round Up

If one is not careful, idle conversation can turn into rumor and rumor become a “buzz.”

Navipedia — The GNSS Wiki

Javier Ventura-Traveset introduces Navipedia at the Munich Satellite Navigation Summit on March 14, 2012. He is responsible for managing Navipedia’s development as well as GNSS education activities for ESA.

Working Papers explore the technical and scientific themes that underpin GNSS programs and applications. This regular column is coordinated by Prof. Dr.-Ing. Günter Hein, head of Europe’s Galileo Operations and Evolution.

In the last 30 years, satellite navigation applications have grown in number and kind, entire new systems have emerged, and existing systems have modernized.

LTE, Positioning, and the Implications for GNSS Over-the-Air Testing

FIGURE 1: (top) Device without case. (bottom) Device with case.

Long Term Evolution (LTE) technology in mobile communications, often called 4G, is making its way into a host of consumer devices. It started with data-only modules for Internet connectivity but quickly made its mark on smartphones, automotive communication, and embedded modules that provide fast and reliable wireless data connectivity to the machine-to-machine (M2M) market.
