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.

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.

Drones to the Rescue!

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.

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.

GSA Issues Second GNSS Market Report: 1.1 Billion Units by 2020

The European GNSS Agency (GSA) has published its second GNSS market report, including a special focus on maritime and surveying application markets and refining its projections of unit and sales revenue volumes through 2020.

According to the new GSA report, the worldwide GNSS market is growing rapidly with total market size expected to increase at an average of 13 percent per year until 2016. At that point, increasing market saturation, price erosion, and platform convergence will reduce the growth rate.
