Global Navigation Satellite Systems Engineering, Policy, and Design
Rohde & Schwarz, based in Munich, Germany, has launched two extensions to the GNSS simulator in its SMBV100A vector signal generator: GLONASS and GPS P-code capability.
The SMBV100A already had the capability to generate a range of GPS and Galileo civil signals as well as wireless standards, including GSM/EDGE, 3GPP with HSPA, LTE, Bluetooth, and Wi-Fi.

The United States GPS program is without doubt the elder statesman of GNSS, but it has had some close calls recently.
At the 2012 Munich Satellite Navigation Summit in March, a high-level Department of Transportation offical and the head of the Air Force GPS Directorate hailed continuing progress on the Global Positioning System’s third-generation satellite development and next-generation control segment (OCX), while apparently escaping — relatively unscathed — the dual perils of Congressional budget cuts and LightSquared interference.

[Updated March 27] We see lots of graphs, schemata, renderings and photographic images of the GNSS satellites and constellations. Perhaps it’s time to rest the eyes with imaginative images of space and satellites through the eyes of children.
Over a number of years, up to 30 of Europe’s Galileo navigation satellites are expected to reach orbit and each of them will be named after a child from one of the 27 European Union countries.

Virginia-based engineering firm UrsaNav Inc. has begun transmitting a variety of low frequency (LF) test signals, including enhanced Loran (eLORAN), as part of a cooperative research and development agreement (CRADA) with the U.S. Coast Guard (USCG).
The test program include a comprehensive palette of signals that are being evaluated for their ability to provide a robust, wide-area, wireless precise timing alternative that can operate cooperatively with GNSS technology or autonomously during GNSS unavailability.

[Updated March 26, 2012] Six experts debatd the exciting – and controversial – claims of faster-than-light neutrinos from physicists who used the Large Hadron Collider (LHC), the world’s largest particle accelerator, in a European experiment that called into question the basics of modern physics.

The 2012 European Satellite Navigation Competition will accept your idea, innovative service or business plan for GNSS applications beginning April 1. Submit your idea online at www.galileo-masters.eu through June 30.
This year, the competition is working with 20 partner regions in Europe, Brazil, the Middle East and North Africa. You do not have to be a resident of the partner regions in order to enter, however you must anticipate basing your business in one of them.

The Air Force is poised to forego putting nuclear detonation detection sensors on the Space-Based Infrared System (SBIRS) satellites, a decision that could complicate efforts to maintain the GPS system by hampering plans to launch multiple, lighter GPS satellites on a single rocket.

Registration is open for the 2012 GPS Partnership Council meeting at the USAF Space and Missile Systems Center, Los Angeles AFB, on Tuesday, May 1 and Wednesday, May 2. As always, participants can compete in a golf tournament on an optional third day of networking and camaraderie on Wednesday, May 3.
The registration deadline is April 27.

Whenever the annual Munich Satellite Navigation Summit came around, some GNSS program was usually in the ascendant, while others had reversed direction or found themselves treading water. This year, perhaps for the first time, all four major providers had reason to celebrate as the event’s organizers cut the cake at their 10th birthday party.

The British Royal Institute of Navigation has given prospective authors a May 4 deadline for abstracts for its annual conference, NAV12. The theme this year is "GNSS and Beyond."
Authors have a broad choice of navigation and technology topics from GNSS, eLoran and integrated systems technology to satellite navigation vulnerabilities to jamming and space weather to low-cost consumer apps design.

As part of an effort to control costs, the U.S. Air Force will be shifting the GPS III program to a fixed-price contract, a Pentagon official told members of a House subcommittee recently.

In a last-ditch effort to salvage its wireless broadband system from official rejection due to interference to GPS, LightSquared Inc. has filed a lengthy rebuttal to the Federal Communications Commission (FCC) notice of its plan to withdraw the agency’s conditional approval of the proposed high-power terrestrial network.

Over the last few years, several of us in the GNSS community have done our best to convince our colleagues, policymakers, and the general public that unsavory characters with GNSS jammers or spoofers are a genuine threat to GNSS and an orderly society.
"But who would want to use a jammer or spoofer?” people ask.
My response? Hackers, because they can. Thieves planning to snatch expensive cargo. A moonlighting employee in the company car. Worse yet, state actors or terrorists targeting our national infrastructure.
