GNSS Evolutions for Maritime

GNSS Evolutions for Maritime

Trends for marine accidents show rising numbers and costs that are mainly associated with collisions and groundings. Research indicates that about 60 percent of these accidents are caused by human error. The majority of them could have been avoided by providing suitable input to the navigation decision-making process, according to a 2008 report by the International Maritime Organization (IMO) Marine Safety Committee. (See IMO 2008 in Additional Resources section near the end of this article.).

FCC Opens GPS-Adjacent Ligado Proposal for Comment

The Federal Communications Commission (FCC) is officially asking for feedback on a proposal by Ligado Networks to repurpose frequencies near the GPS band for a terrestrial broadband network. The long-delayed public notice and comment period is a step in the approval process, although there is no assurance that Ligado’s plan for a new wireless service — which may still cause interference to GPS receivers — will get the go-ahead.

Up in the AIRR

Anyone who has sat through several iterations of a slide presentation by the Federal Aviation Administration (FAA) can’t help but wonder if there isn’t a better way to do things.

As speakers flip through an exhaustively vetted series of PowerPoint slides, squeezing out a new bullet point or two from one version to the next six months later, watching paint dry seems like a more productive — and briefer — use of one’s time. The agency sometimes brings a whole new meaning to the concept of geological time.

COMPASS POINTS

Engineering specialties

Algorithm development, Kalman filtering, GNSS/INS integration, digital signal processing, embedded software, system integration

Favorite equation

Kennedy really likes the foundational differential equation, the basis of Kalman filtering, because it can become so many different things:

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.

GLONASS logo_lo

GLONASS and PNT in Russia

The legal and regulatory framework of the Russian Federation covers not only the GLONASS system, but the country’s overall positioning, navigation and timing (PNT) system as well.

The term PNT is a synonym for navigation activities as defined in the Federal Law on Navigation Activities. The PNT system in the Russian Federation is defined as the combination of administrative and technical means that provide spatial and time data to all user groups, with GLONASS as a key element.

What are the fundamentals of an effective GNSS test plan?

Q. What are the fundamentals of an effective GNSS test plan?  

A. One aspect of GNSS development that engineers often find challenging is the lack of common testing standards and procedures. This can make life difficult for the engineer tasked with constructing a test plan for a new GNSS-enabled system. How much testing is proportionate, at which stages of development? What are the key performance parameters to measure? What apparatus is best suited to the application, and what are the appropriate pass/fail criteria?

How Privatizing Air Traffic Control Could Affect Satellite Navigation’s Role in Aviation

How Privatizing Air Traffic Control Could Affect Satellite Navigation’s Role in Aviation

The satellite-based NextGen program is in trouble — no question about it.

The Federal Aviation Administration (FAA) air traffic modernization effort will likely cost triple its original $40-billion program budget and need an extra decade — until 2035 or beyond — to reach completion, according to 2014 testimony by Department of Transportation (DoT) Inspector General Calvin Scovel.

SBAS and RNSS: The Unsung Heroes of GNSS

Okay, if I had wanted to pander to GNSS fans, I might have called this, “Making Great Greater.”

But there are only so many superlatives that can be lathered on this remarkable technology before simple praise turns into hagiography.

So, it’s time once more to give a little love to those unsung heroes of GNSS: the augmentations and regional navigation satellite systems.

Galileo Themes, Threads and Visions

Europe’s space community rang in the New Year with two of its brightest annual fixtures: the European Union (EU) Space Policy conference in Brussels and the European Space Agency (ESA) media briefing in Paris.

The events brought out all of the relevant voices and served to illustrate not only the disposition of materiel and troops but also their intent and even the level of morale.
