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

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.

INS Face Off

The automobile versus the horse and buggy. Cloud computing opposite desktop software. The trend is predictable, yet it is always surprising when one technology takes over the market space of another. After all, television did kill off the radio star.

House Action Would Thwart GPS-Aided Tracking of Commercial Trucks

Independent truck operators and a general fear of government surveillance led to passage of an amendment today (June 29, 2012) that would prohibit U.S. agencies from implementing any rule requiring GPS tracking or other devices to be installed in passenger or commercial vehicles.

In a voice vote on the floor of the U.S. House of Representatives, congressmen approved the amendment to H.R. 5972, the Transportation, Housing and Urban Development and Related Agencies Appropriations Act of 2013.
