NovAtel Launches TerraStar-L Correction Service

NovAtel Inc. has announced the launch of its TerraStar-L, a new 40 centimeter precise point positioning (PPP) correction service. TerraStar-L is a subscription based correction service that delivers GNSS correction data via satellite to users of precision navigation systems.

The company says that position accuracy of 40 centimeters makes TerraStar-L ideal for broad accuracy applications such as agriculture, GIS or unmanned vehicle navigation, particularly where tree lines, buildings and other obstructions can be an impediment to continuous positioning.

Sandy Kennedy: Here to Stay

Sandy Kennedy and her husband Arlin Amundrud

>>Sandy Kennedy’s Compass Points

Sandy Kennedy grew up in Miami. Miami, Manitoba, Canada, that is — a town of 150 people with a school, a café, a defunct railroad station, and an ice skating rink.

Now she’s director and chief engineer in charge of receiver core cards at NovAtel Inc., a developer and manufacturer of high-precision GNSS products headquartered in Calgary, Alberta. It’s a long way from where she started, but then again, maybe not.

BBC, Chronos Report on Lengthy Disruptions Caused by GPS Timing Problem

The British Broadcasting Corporation (BBC) said yesterday (February 2, 2016) that the recent decommissioning of a GPS satellite led to difficulties for listeners receiving digital radio signals.

In a response to the reported issues, the BBC said: "The outages were caused by a rogue GPS satellite (SVN23), which was taken out of service in the evening of 26 January."

State of Play in the European Union

Global navigation satellite systems have become core elements of the global economy. Essential for many civilian applications and innovations, GNSS brings rapidly growing economic benefits due to convergence of GNSS with smartphones, geospatial data, unmanned aerial vehicles, automated driving systems and other commercial technologies.

GNSS Receiver Manufacturers Thwart Jamming, Spoofing

[SIGNALS exclusive] With customers demanding greater security against hackers and jamming, GNSS receiver manufacturers are incorporating a widening array of techniques to thwart interference both natural and nefarious.

But sometimes security-related innovations take a while to catch on.

Single Antenna, Dual Use

A GNSS single-antenna system can be compared to a single-pixel camera. Electromagnetic waves traveling 20,000 kilometers from every overhead direction can reach us. Yet once at the antenna, this diverse set of information is collapsed into a single magnitude and phase value, then sent off to the receiver so that value can be extracted.

Federal Agencies Move to Close Most NDGPS Sites

A Federal Register notice published yesterday (August 18, 2015) seeking comment on plans to shut down a large portion of the Nationwide Differential GPS (NDGPS) network marks the effective end of a program that spurred a hard-fought controversy in the era of Selective Availability (SA).

LightSquared Submits GPS Market Study to FCC

A “GPS market review” submitted to the Federal Communications Commission (FCC) this week diverges in methodology and results from a preliminary study of U.S. benefits of the Global Positioning System provided earlier this year to the National Space-Based Positioning, Navigation, and Timing (PNT) Advisory Board.

Study: GPS Contributed More Than $68 Billion to the U.S. Economy

GPS contributed more than $68 billion to the U.S. economy in 2013, according to the preliminary results of a new study presented to the National Space-Based Positioning, Navigation, and Timing (PNT) Advisory Board.

And the study’s author, Irv Leveson, a consultant to ASCR Federal Research and Technology Solutions, LLC, described that figure as conservative because it did not fully incorporate a host of GPS applications including those depending on GPS timing information.
