Denver International Airport (DIA) has fully implemented its new arrival and departure procedures, the next phase in the Federal Aviation Administration’s mass overhaul of U.S. airspace, called NextGen. Denver is among the airports at the front end of the adoption process, and is highlighted in an in-depth feature in the Denver Post.
According to the article, “The recently completed phase at DIA trims arrival and departure fuel costs by eliminating several intermediary steps. The traditional system requires an airplane to come into and out of cruising altitude by firing its thrusters at every new altitude level, wasting hundreds of pounds of fuel… The traveling public will not likely notice an immediate difference in travel time, but proponents hope that the early investment pays off in the end.”
The FAA predicts that NextGen improvements will reduce flight delays by 38 percent and lead to a 1.4-billion-gallon total reduction of fuel burn by 2020.
ST-Ericsson, a joint venture of STMicroelectronics and Ericsson, has sold its mobile connectivity GNSS business to Intel.
ST-Ericsson, which focuses on mobile and wireless chips, announced the sale on Tuesday without naming the buyer. An Intel spokesman later said the U.S. chipmaker bought the assets.
According to ST-Ericsson, the sale “represents another step in the execution of Ericsson’s and ST’s announcement of March 18, 2013,” when the company announced it was winding down the joint venture. Ericsson will assume 1,800 employees and contractors, with the largest concentrations in Sweden, Germany, India and China. ST will assume 950 employees, primarily in France and in Italy.
In addition to the assets and intellectual property rights associated with this business, 130 employees in Daventry, UK, Bangalore, India, and Singapore are anticipated to join Intel at closing of the transaction, and will be added to Intel’s already-existing GPS assets.
The closing of the transaction is subject to regulatory approvals and standard conditions and is expected to be completed in August. ST-Ericsson estimates the proceeds from the sale, combined with the avoidance of employee restructuring charges and other related restructuring costs, will reduce the joint venture’s cash needs by approximately $90 million.
“Today’s transaction validates the leading innovation developed by ST-Ericsson in mobile navigation systems and marks a further important step towards the execution of our shareholders’ decision to exit from ST-Ericsson” commented Carlo Ferro, President and CEO of ST-Ericsson. “I am pleased that this organization will continue to develop leading-edge technologies and delighted that the team found a new home at a leading player in the semiconductor industry.”

UPDATE, May 24, by Richard Langley: The Centaur upper stage with the payload still attached was photographed from Tavistock, Devon, in the U.K. by Andy Smith. As can be seen from the ground trace figure in an earlier GPS World news item, the Centaur passed over the U.K. following MECO1, the first main engine cutoff. From Europe, the Centaur could be easily seen by reflected sunlight against the background stars. Its maximum (apparent) brightness magnitude has been estimated as -1 or -2. (Sirius, the brightest star in the night sky, has a magnitude of -1.5; Betelgeuse in the constellation Orion has a mean magnitude of about 0.4; and the limiting visual magnitude for the unaided eye is about 6.)
Smith’s photograph was taken at 21:58:38 UTC (start) with a Canon EOS 450D Digital Rebel camera with an 18-55mm zoom lens. The camera settings were: focal length 55mm, aperture f/5.6, and an exposure of 8 seconds at an ISO value of 1600. Two images are shown below: the original, as obtained from the camera, and a greyscale image with edge enhancement.
The Centaur can be seen traveling left to right and starts its track as it crosses the constellation of Cygnus. There’s a slight wobble at the beginning as the shutter release was pressed. The glow at the bottom of the frame is from a streetlight. The elevation angle of the Centaur was approximately 12 degrees.
SVN66 will operate as PRN27 and it will eventually occupy the C-2 orbital slot, replacing SVN33/PRN03, a Block IIA satellite launched in 1996. SVN66 is currently in a drift orbit about 400 kilometers above the operational constellation. It should reach the C-2 slot within a few days from now. The satellite has already been added to the broadcast almanac although it has not yet started to transmit standard signals. It is currently marked as unhealthy in the almanac and will remain so, even after standard signals are switched on, until testing is completed sometime this summer.

A U.S. Air Force Global Positioning System satellite built by Boeing was successfully launched May 15. The fourth GPS IIF satellite, Space Vehicle Number (SVN) 66, was carried aboard a United Launch Alliance Atlas V Launch Vehicle at 5:38 p.m. EDT (21:38 UTC) May 15 from Cape Canaveral Air Force Station, Florida.
The new capabilities of the IIF satellites will provide greater navigational accuracy through improvements in atomic clock technology; a more robust signal for commercial aviation and safety-of-life applications, known as the new third civil signal (L5); and a 12-year design life providing long-term service. These upgrades improved anti-jam capabilities for the warfighter and improved security for military and civil users around the world, the Air Force said in a statement.
“I’m extremely pleased with today’s launch and delighted to be part of this mission that enhances our nation’s critical GPS capability. Thanks to the superb efforts of the of the 45th and 50th Space Wings, United Launch Alliance, our industry partners, the Atlas V and GPS IIF launch teams, the GPS IIF-4 mission was successfully carried out,” said Col. Bernie Gruber, director of the Space and Missile Systems Center’s Global Positioning Systems Directorate.
“The GPS constellation remains healthy and continues to meet and exceed the performance standards to which the satellites were built. Our goal is to deliver sustained, reliable GPS capabilities to America’s warfighters, our allies and civil users around the world, and this is done by maintaining GPS performance, fielding new capabilities and developing more robust modernized capabilities for the future,” said Colonel Gruber.
Here are videos of the launch:

The chief designer of the BeiDou Navigation Satellite System said China will advocate the use of the system, which will be compatible with new devices, “so that Beidou can function properly and independently even if something goes wrong with the GPS.”
Sun Jiadong, chief designer of BDS and an academician of the Chinese Academy of Sciences, made his comments in an interview with The Beijing News, as reported by the Chinese government’s website.
He added that this compatibility is the only way to ensure the protection of national information. “Safety issues abound in economic areas,” said Sun. “Ordinary people may have few concerns about the security of information but it is of vital significance.”
The development of Beidou also largely depends on the government’s involvement. “Even though the enterprises spare no effort in developing the system, the products they make would not be available for mass production, which will in turn be reflected by the prices. The government has to promote the research and development of the system,” Sun said. Sun cited the governments of Beijing, Shanghai, and Guangzhou as examples of local governments that were effectively helping to develop the BDS.
The use of Beidou could go beyond basic navigation functions and extend to the civilian market. It would take longer for the BDS to be available for civilians, said Sun. The use of Beidou on mobile phones relies on the development of a small and power-efficient chip. Otherwise the phone cannot be used.
When asked about when and how the cost of developing the BDS will be recovered, Sun reiterated that Beidou was developed to ensure the security of national information, and not to make profits.
The Beidou global navigation system will be available by 2020 with the launching of more than 30 satellites.
The fourth International Colloquium on Scientific and Fundamental Aspects of the Galileo Programme will be held in Prague, Czech Republic, December 4–6.
Since 2007, the worldwide scientific community has met every two years to discuss the possibilities for boosting the scientific use of Galileo and for contributing to the development of the GNSS.
The event is always organized in one of the 20 European Space Agency’s Member States, and makes an essential contribution to ESA’s implementation and definition of the evolution of the European GNSS. The gathering of major academic players provides a scientific reference for institutional executives and industry, as well as offering a unique platform for promoting innovative GNSS initiatives at large.
The colloquium focuses on four major areas of research:
Scientific applications in meteorology, geodesy, geophysics, space physics, oceanography, land surface and ecosystem studies, using either direct or reflected signals, differential measurements, phase measurements, radio occultation measurements, using receivers placed on the ground, in aircraft or on satellites.
Scientific developments in physics, dealing with future GNSS, particularly in testing fundamental laws in astronomy and in quantum communication. Relativistic reference frames and relativistic positioning will be addressed.
Aspects of metrology such as reference frames, onboard and ground clocks, and precise orbit determination.
Scientific aspects of satellite navigation and positioning such as signal propagation, tropospheric and ionospheric corrections and the means to model and mitigate multipath and interference.
The various possibilities to use navigation satellites such as Galileo for scientific purposes will be reviewed and the use of scientific applications to contribute to make the most of the present systems and define their evolution will be scrutinized.
The conference is being organized as a series of plenary talks and two parallel half-day sessions.
Online submission of abstracts is open until June 14 through the colloquium website, where other detailed information is also available.
skobbler brings together hybrid online and offline worldwide maps and full turn-by-turn navigation in a low-priced app with the launch of GPS Navigation & Maps for Android.
skobbler is looking to exploit the weaknesses of established Android navigation alternatives with the fully featured GPS Navigation & Maps, which offers an improved experience compared to both Google Maps and high-priced third-party alternatives, skobbler said. GPS Navigation & Maps is effectively two apps in one, with both online and offline turn-by-turn navigation and digital mapping for smartphones.
Using open-source digital map OpenStreetMap and powered by the skobbler NGx map engine, GPS Navigation and Maps has full online and offline capability. The £1 price includes worldwide online functionality as well as an installable map of one country of choice for offline use. From here, users have the option to in-app purchase individual cities, states, countries and continents to use offline, and worldwide maps are available as standard for online use. Existing users of ForeverMap 2 will receive a free upgrade to GPS Navigation & Maps. New users can either purchase the full app or try GPS Navigation & Maps’ free app with unlimited online functionality and a 14-day navigation trial.
While Google Maps is free to download and use, its offline functionality is restricted. Users cannot perform any searching or routing tasks without an Internet connection, which means that when abroad or in low signal areas they either have to pay expensive roaming costs or spend a significant time without map coverage, limiting its usability while traveling, skobbler said. Expensive alternatives such as Co-Pilot Live or TomTom UK & Ireland/Europe do offer premium features and offline navigation, yet none of them give users a choice of which areas they want to use online and which offline. Most premium sat nav apps generally cannot be used as travel apps at all, as their pure map functionalities are limited at best. GPS Navigation & Maps is the perfect blend. Offering the best of both worlds for a fraction of the price, it can be relied upon to deliver any place, at any time, and being two great apps in one offers a fantastic cost-to-benefit ratio and unbeatable flexibility for consumers, skobbler said. Individuals can build their own navigation and maps app depending on what resources they use the most, and more effectively manage the limited storage space on their devices, skobbler said.
GPS Navigation and Maps has full turn-by-turn navigation, worldwide mapping and all features of the software accessible both online or offline. This unique move, and market first, is made possible thanks to skobbler’s NGx map engine, which delivers a seamless browsing experience with ultrafast real-time rendering and stunning map visuals, skobbler said. NGx also offers a range of unique map styles to, for example, accentuate color density for outdoor use to improve clarity. Maps are highly customizable with control over features such as online/offline functionality, map display (style and zoom), routing, map matching and more.
“We’re very proud to launch the first navigation product utilising our powerful NGx mapping engine,” said skobbler CTO Philipp Kandal. “Being the first and only company on the Android platform to offer full online and offline capability for both mapping and navigation, we hope both new users and our existing customers will be won over by the high performance and flexibility GPS Navigation & Maps offers. We’re already working on future updates and have a few powerful additions lined up to improve the app’s functionality and flexibility even further in the coming months.”
Additional maps beyond the free map provided will be available via in-app purchases for offline use. In keeping with the low price for the initial app purchase, add-ons are similary competitive and are priced at £0.77 for cities, £1.11 for states, £2.22 for a whole country, £4.44 for a continent and just £7.77 for the entire planet, so users can quickly and easily supplement their map coverage as they see fit.
skobbler is committed to providing regular updates to users to keep maps fresh and accurate, and promises a range of new premium features in future updates. GPS Navigation & Maps is now available from the Google Play Store, with existing ForeverMap 2 users able to upgrade for free.
The full version of GPS Navigation & Maps, including one free offline country map, can be downloaded.
Accord Technology’s NexNav GPS receiver will be supporting FreeFlight Systems with its recently awarded FAA Capstone Retrofit Project.

Rohde & Schwarz and 7Layers have verified and validated the synchronized test approach to determine the Envelope Correlation Coefficient (ECC), a value characterizing the antenna subsystem of multiple-input and multiple-output (MIMO) LTE devices. The Synchronized ECC approach delivers significantly shorter test durations and repeatable results, ultimately resulting in reduced costs. Long term, this collaboration will also help product manufacturers develop devices that achieve greater data speeds over LTE by using highly optimized MIMO antenna configurations, the companies said.
The Synchronized ECC approach involves over-the-air transfer of measured data between the test platform and a mobile device in a synchronized fashion. This method, proposed by a leading U.S. wireless carrier, does not require any overhead or user interaction to calculate the ECC, making it easier and faster to execute test versus other approaches. 7Layers test engineers used the Rohde & Schwarz TS8991 OTA Performance Test System and software option R&S AMS32-K30 as a test platform for validation.
”7Layers is excited to help bring an ecosystem of vendors together to advance testing of LTE enabled devices utilizing MIMO,” commented Mahesh Kodukula, business development manager of 7Layers. ”As an accredited test laboratory, we provided a realistic test environment for our partners.”
”We are pleased to enable this type of testing on our R&S TS8991 OTA test platform and to offer this functionality to a variety of customers that have been waiting for this feature,” said Thorsten Hertel, OTA product specialist at Rohde & Schwarz. ”We strive to meet the industry needs of the leading edge development of LTE devices.”
