u-blox Announces Profit, Revenue Advances in 2014

Thalwil, Switzerland–based u-blox reported revenue and profit growth in its most recent annual report, driven by strong sales in its GNSS and wireless chipset and module business.
 
Consolidated revenue was CHF270 million (US$276.7 million) in 2014, a growth of nearly 23 percent compared to 2013 while net profit increased by 39.6 percent to CHF34.4 million (US$35.2 million), representing a 12.7 percent net profit margin for the year.

Flying Blind

It’s 10 p.m. somewhere over the vast oceans that comprise three-quarters of the Earth’s surface. Do you know where your airplane is?

Well, you could, but maybe you don’t.

The anniversary of the disappearance of Malaysia Airlines flight MH370 came and went in March with the fate of the Boeing 777 still unknown.

It didn’t have to happen.

GAO Report: More Delays, Cost Increases for OCX, GPS III

New delays and higher costs should be expected for both the GPS III satellite program and GPS-OCX, the new GPS ground system, federal watchdogs warned in a new report.

The Government Accountability Office (GAO) said both programs are in the process of rebaselining, that is, resetting their estimated schedules and costs. In the case of the Next Generation Operational Control System (GPS OCX), which is essential for full operation of the new GPS III satellites, the changes could be significant.

DHS, NIST Make Progress on Protecting GPS

Two agencies charged with helping protect America’s critical infrastructure are working on ways to safeguard GPS receivers, particularly those used to tap the signal for essential timing data.

The Department of Homeland Security (DHS) is building on its more recent, technically focused research to identify and mitigate risks.

Renewed Spectrum Fight Emerges between GPS, LightSquared at ABC Workshop

Spectrum-related tensions reemerged during a workshop on Thursday (March 12, 2015) organized to gather feedback on a testing plan to help protect GPS receivers.

The plan is part of the GPS Adjacent-Band Compatibility (ABC) assessment — a wide-ranging effort to determine the power levels at which services operating in frequencies next those used by GPS and other GNSS systems can broadcast signals without causing interference to GPS signals.

GNSS and Precision Farming

GNSS and Precision Farming

Nowhere has the fact that GNSS can guide things besides military weapons and transport manifested itself more profoundly than in agriculture.

While Google and automotive manufacturers struggle to figure out how to put autonomous vehicles on the highway, farmers have been using GNSS for well over a decade to guide equipment through their fields — along with a host of other ag-related, site-specific applications.

Indeed, GNSS — along with an array of other high-tech resources — is transforming agriculture at an accelerating rate.

How does a GNSS receiver estimate velocity?

How does a GNSS receiver estimate velocity?

Q: How does a GNSS receiver estimate velocity?

A: Stand-alone single-frequency GNSS receivers represent the largest slice of the commercial positioning market. Such receivers operate mainly in single point position (SPP) mode and estimate velocity either by differencing two consecutive positions (i.e., approximating the derivative of user position) or by using Doppler measurements related to user-satellite motion.
