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.

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.

[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.

[Updated July 2] Appropriators in both the U.S. House and Senate have slashed next year’s funding for support of the civil portion of the GPS program. Lawmakers halved the portion of the Federal Aviation Administration budget dedicated to supporting the civil signals as well as the ground network monitoring of those signals.

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.
