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.

Drones to the Rescue!

August 1994, early morning. Spain’s Central Pyrenees Mountains still in darkness.

At the outset of an ascent to a 3,000-meter peak along the international border, one of the co-authors encounters a group of tourist hikers who have begun searching for a colleague who had left the camp the previous evening. In the pre-sunrise gloom, helicopters cannot yet operate.

A week later, the body of the hiker is found. The rescue efforts came, unfortunately, too late.

Addition of Leap Second Highlights Campaign for Its Elimination

[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.

With the first two Galileo in-orbit validation (IOV) spacecraft working well, the European Space Agency (ESA) has decided to end the mission of its pioneering GIOVE-A satellite that had long exceeded it original purpose and design life.

Meanwhile, with the next Galileo launch approaching, ESA has expanded its Radio Navigation Laboratory (RNL) to meet the testing needs of Europe’s GNSS program.

IP Rights and Wrongs

As Desi Arnaz often said to Lucille Ball during an “I Love Lucy” episode on TV, “You’ve got some ’splaining to do.”

I refer, of course, to the untoward and unexpected initiative by the British Ministry of Defense (MoD) to patent the technical innovations that underlie the planned next generation of civil GNSS signals.
