Septentrio Tracks BeiDou GNSS Signals Using New ICD

Septentrio reported today (January 8, 2013) that the Belgium-headquartered GNSS receiver manufacturer has successfully computed a position/velocity/time (PVT) calculation using BeiDou/Compass satellites in a three-constellation (GPS+GLONASS+BeiDou) solution.

"We are positively surprised of the better than expected performance coming out of what we characterize to be ‘a quite mature constellation,’” Laurent Le Thuaut, Septentrio’s business development manager, told Inside GNSS in an e-mail.

GPS Coalition to FCC: LightSquared’s Requests Must Not Come at Expense of Critical Services

A GPS advocacy group has urged the Federal Communications Commission (FCC), as it considers expansion of terrestrial use of the mobile satellite spectrum (MSS) adjacent to GPS, to recognize that expansion “not come at the expense of critical GPS services.”

Civil Galileo System Poses New Options for Secure Services

Conceptual design of ULTRA (ultra low-cost PRS receiver)

When European leaders first took up the idea of creating their own GNSS system nearly 20 years ago, they held up the concept of civilian control as a crucial differentiator from existing services operated by national military establishments.

As Galileo nears its operational phase, that principle may manifest itself in a surprising form: the opportunity to offer a range of security-oriented positioning and timing solutions in place of the all-or-nothing alternatives on encrypted services maintained by defense agencies.

Longer Show Hours, Fewer Days for ION GNSS 2013 Exhibitors

ION GNSS 2012

Companies who exhibit at the Institute of Navigation GNSS conference next September will have longer exhibit hall hours to work the floor – but fewer days to do so – at the 2013 event in Nashville, Tennessee.

Based on feedback from exhibitors, ION will eliminate the Friday hours for the industry show and increase the Wednesday and Thursday hours next year.

DoT Gives GPS Spectrum Protection Team Award

The GPS Spectrum Protection Team has received the U.S. Department of Transportation (DoT) Partnering for Excellence Award for outstanding performance in support of the government and industry-wide assessment of potential impacts to GPS operations and safety.

The spectrum protection team played an important role in responding to the proposed LightSquared wireless broadband system’s spectrum plan.

An experimental GPS receiver, built by Surrey Satellite Technology Limited (SSTL), has successfully achieved a GPS position fix at a 23,300-kilometer altitude — the first position fix above the GPS constellation on a civilian satellite, according to the company.

SSTL’s SGR-GEO receiver is collecting data that could help the company to develop a receiver to navigate spacecraft in geostationary Earth orbit (GEO) or even in deep space.

GNSS IC Sales Approach $3 Billion Mark

ABI Research: GNSS IC market shares in non-cellular applications

Global sales of the smallest GNSS form factor — the integrated circuit (IC) — will exceed $3 billion next year, driven in large part by incorporation of position/location capabilities in smartphones, according to a leading research organization.

U.S. Space-Based PNT Executive Leadership to Change

A top leadership change is under way at one of the most important U.S. GPS policy and management organizations, the National Space-Based Positioning, Navigation, and Timing (PNT) Coordination Office (NCO).

Anthony (Tony) Russo, who has served as NCO director for the past three years — and as deputy director for two years before that, has accepted a new position with the National Aeronautics and Space Administration (NASA).

Our Harvest Being Gotten In

This is, as they say in Hollywood, a wrap.

The final issue of our seventh year heads off to the printer. And tomorrow I will point my car north and west, returning as generations of Americans have done over the centuries to the family farm, the “home place,” for Thanksgiving.

Because this is the season for gathering in and counting up. For gratitude at what we have received in the year past, and for those untoward things that we have avoided.

ICAO AN-Conf/12: 12th Air Navigation Conference

The International Civil Aviation Organization, a specialized agency of the United Nations, will hold its 12th Air Navigation Conference (AN-Conf/12) at the ICAO headquarters assembly hall in the Quartier National of Montreal from November 19 through November 30, 2012. The conferences take place every 10 years.

Taking Turns at the Fiscal Cliff

The GPS program has taken a fiscal hit that will delay critical plans to begin multi-satellite launches and could ultimately hamper the Air Force’s ability to keep the constellation at its current level of service.

The shortfall is just one of the challenges facing the program over the next four months as the current six-month budget extension winds down, the government’s ability to borrow runs out, and, barring a fast political deal, the onerous budget cuts set up under sequestration kick in.
