Galileo & EGNOS Evolution

Prof. Dr. Günter Hein

A global navigation satellite system seems like such solid thing, like the pyramids, perhaps, or a mountain. Permanent, fixed, immutable.

Nor is this surprising. After all, GNSS distinguishes itself from many other technologies of the moment by its grounding in a large and widespread infrastructure: a master control station, launch facilities, far-flung monitoring stations, the space segment with dozens of massive satellites that can operate 20 years or more as did a recently retired GPS Block IIA spacecraft.

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 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

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.
