Global Navigation Satellite Systems Engineering, Policy, and Design
Topcon Positioning Group has announced the launch of Topcon Delta, its new deformation monitoring solution for construction, tunneling, and mining.
According to the company, Topcon Delta is a system of software and hardware components, which delivers accurate and reliable monitoring measurements and associated reporting to provide protection of assets during works.

Air Force Space Commander Gen. John Hyten at subcommittee hearingWhile acknowledging the fury over problems with the new GPS ground system, the head of Air Force Space Command told lawmakers this month that finishing the program with the current contractor was the best way forward.
That contactor, Raytheon, is years behind on the Next Generation Operational Control System (OCX), a project whose price tag may now top $4 billion.
By Inside GNSSAnyone 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.

Prof. Dr. Günter HeinA 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.

This webinar was presented on Thursday, April 7, 2016, as Inside GNSS continued its series of web seminars focusing on the rapidly expanding field unmanned aerial vehicles (UAVs) in a webinar sponsored by Applanix Corporation.
The recent adoption of UAVs for airborne mapping applications promises to greatly reduce the cost and complexity of collecting geospatial data and images for a broad range of applications.

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.

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.

Working Papers explore the technical and scientific themes that underpin GNSS programs and applications. This regular column is coordinated by Prof. Dr.-Ing. Günter Hein, head of Europe’s Galileo Operations and Evolution.
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?

Southampton’s Town WallsThe Royal Institute of Navigation will host a one-day event on The Future of GNSS with speaker Prof. Terry Moore on April 21, 2016 at the Warsash Maritime Academy in Southampton, England.
The speaker will outline the future of GNNS and its systems, anticipated changes and the impact of these developments.
This meeting which is joint with the NI and UK Hydro Society will be followed by the RIN Solent branch AGM.
This event is free. Prior booking not required, guests are welcome.

As the contractor for the new GPS ground system works its way through a make-or-break 90-day evaluation period, the U.S. Air Force (USAF) is weighing whether it should look at leapfrogging past that program and shifting control of the newest GPS satellites to a new common ground system for Air Force space assets.
The Next-Generation Operational Control System or OCX, currently under development by Raytheon, is essential to integrating the GPS III satellites into the U.S. GNSS constellation and operating them at their full potential.

Representatives of the world’s GNSS providers outlined the current plans and progress of their systems at the 2016 Munich Satellite Navigation Summit in Germany.
BeiDou has entered its transition period from Phase II to Phase III, with test and validation of the next phase with its new signal structures and frequencies taking place through the second half of 2017, said Jun Shen, deputy director for International Research at the China Satellite Navigation Office. In the meantime, “there will be a coexisting of Phase II/III BeiDou signals.
