FAA Warns of GPS Outages This Month During Mysterious Tests on the West Coast

As reported by GizmodoStarting today, it appears the US military will be testing a device or devices that will potentially jam GPS signals for six hours each day. We say “appears” because officially the tests were announced by the FAA but are centered near the US Navy’s largest installation in the Mojave Desert. And the Navy won’t tell us much about what’s going on.

The FAA issued an advisory warning pilots on Saturday that global positioning systems (GPS) could be unreliable during six different days this month, primarily in the Southwestern United States. On June 7, 9, 21, 23, 28, and 30th the GPS interference testing will be taking place between 9:30am and 3:30pm Pacific time. But if you’re on the ground, you probably won’t notice interference.
The testing will be centered on China Lake, California—home to the Navy’s 1.1 million acre Naval Air Weapons Center in the Mojave Desert. The potentially lost signals will stretch hundreds of miles in each direction and will affect various types of GPS, reaching the furthest at higher altitudes. But the jamming will only affect aircraft above 50 feet. As you can see from the FAA map below, the jamming will almost reach the California-Oregon border at 4o,000 feet above sea level and 505 nautical miles at its greatest range.

I gave the Naval Air Warfare Center Weapons Division a call yesterday, but they couldn’t tell me much.
“We’re aware of the flight advisory,” Deidre Patin, Public Affairs specialist for Naval Air Warfare Center Weapons Division told me over the phone. But she couldn’t give me any details about whether there was indeed GPS “jamming,” nor whether it had happened before. Patin added, “I can’t go into the details of the testing, it’s general testing for our ranges.”
As AVWeb points out, Embraer Phenom 300 business jets are being told to avoid the area completely during the tests. The FAA claims that the jamming test could interfere with the business jet’s “aircraft flight stability controls.”
GPS technology has become so ubiquitous that cheap jamming technology has become a real concern for both military and civilian aircraft. And if we had to speculate we’d say that these tests are probably pulling double duty for both offensive and defensive military capabilities. But honestly, that’s just a guess.
These tests are naturally going to fuel plenty of conspiracy theories about mind control, weather modification, and aliens—especially with China Lake’s proximity to both large population centers like LA and Las Vegas, and the fact that Area 51 is practically just down the road. But it doesn’t take a conspiracy theorist to tell us we’re fucked if terrorists or shitty teenagers make it a habit of jamming GPS signals for everybody.
If you experience any significant GPS interference this month or know the “real” reason behind these test (aliens, right?) please let us know in the comments.

Is This Gliding Electric Bus the Future of Public Transportation?

As reported by Popular Mechanics:If you've ever been stuck on the bus wondering how and when the humble vehicle will make the jump into the future, a fresh concept video could ease your transportation-related concerns.

The mass-transit concept, created by Beijing-based Transit Explore Bus, was shown off at the 19th China Beijing International High-Tech Expo (CHITEC) over the weekend. As the video below shows, the electric transit elevated bus glides above traffic and is designed to allow cars to pass beneath it.



The evolutionary Monorail concept is also apparently cheaper and quicker to develop than subway systems, and can hold up to 1,400 passengers. With Hebei's Qinhuangdao City set to adopt the gliding apparatus in the second half of this year, we might just see the Straddle Bus cruising over cars in no time.

Tesla Tests Self-Driving Functions with Secret Updates to Its Customers’ Cars

As reported by MIT Technology ReviewWhen Tesla Motors introduced the Model S sedan in 2012, one of its many notable features was an always-on cellular based Internet connection. A Tesla executive explained today that it has turned into a powerful advantage in the company’s contest with other carmakers and Internet giants such as Google to get self-driving cars onto public roads.

Tesla can pull down data from the sensors inside its customers’ vehicles to see how people are driving and the road and traffic conditions they experience. It uses that data to test the effectiveness of new self-driving features. The company even secretly tests new autonomous software by remotely installing it on customer vehicles so it can react to real road and traffic conditions, without controlling the vehicle.

“The ability to pull high-resolution data from these vehicles and to update the vehicles over the air is a significant part of what’s allowed us in 18 months to go from very behind the curve to what is today one of the more advanced autonomous or semi-autonomous driving features,” said Sterling Anderson, director of Tesla’s Autopilot program, at MIT Technology Review’s EmTech Digital conference in San Francisco on Tuesday (see “No Industry Can Afford to Ignore Artificial Intelligence”).

Tesla began bundling a suite of new sensors into its vehicles in 2014, saying it was for a new emergency braking feature.

But the 12 ultrasonic sensors positioned around the car sense nearby objects, and the forward-facing cameras and radar units were intended for bigger things. Tesla engineers began using data streaming from cars with those sensors and information on their locations to start testing autonomous driving features.

“Since introducing this hardware 18 months ago we’ve accrued 780 million miles,” said Anderson. “We can use all of that data on our servers to look for how people are using our cars and how we can improve things.” Every 10 hours Tesla gets another million miles worth of data, he said.

Tesla’s engineers initially test new self-driving software against those records. Any that perform well can also be tested by secretly installing them onto customer vehicles and watching how they respond to conditions on the road, although the software doesn't actually control the car.
“We will often install an ‘inert’ feature on all our vehicles worldwide,” said Anderson. “That allows us to watch over tens of millions of miles how a feature performs.”

Anderson’s team can also watch closely when a new feature is activated. For example, he showed a chart illustrating how self-driving Teslas using the Autopilot feature hold themselves much more tightly to the center of the lane than humans do when steering the car. Since its launch last October, Tesla has logged 100 million miles of vehicles steering themselves (see “10 Breakthrough Technologies 2016: Tesla Autopilot”).

Tesla’s ability to pull data from its cars and even covertly test autonomous driving software is likely unique. Google has demonstrated some of the most advanced self-driving technology, but it can only pull data from its fleet of prototypes, likely smaller and less widely distributed than the collection of Tesla vehicles on the road.

Other carmakers, such as GM, are also working on self-driving. But they have not embraced the idea of Internet connectivity and over-the-air updates in the way Tesla has.

However, Tesla’s strategy of using its data infrastructure to test and develop its technology in public could run into problems. Google restructured its autonomous car program in 2014 after the concerning results of an experiment in which Google employees could use self-driving prototypes. People quickly became complacent about the technology’s abilities, despite the fact that they were supposed to be ready to take over at all times.

“One guy noticed that his cell-phone battery was low, pulled out his laptop, and plugged it in at 65 miles per hour on the freeway,” Chris Urmson, who leads Google’s project, said at the EmTech event today. “We thought, this is not good.” Google committed itself to car designs without steering wheels or pedals, piloted by software alone (see “Lazy Humans Shaped Google’s New Autonomous Car”).

Anderson takes a different view. He said Tesla’s data-centric strategy will allow the company to keep advancing the company’s Autopilot technology, for example to include the ability to drive in more urban conditions and handle intersections. Tesla must be aware of drivers’ expectations, but doesn’t need to take them out of the equation altogether, he said.

“Autopilot is not an autonomous system and should not be treated as one,” said Anderson. “We ask drivers to keep their hands on [the wheel] and be prepared to take over.”

14 Galileo GNSS (GPS) Satellites Now in Orbit

As reported by GPS WorldThe Galileo satellite navigation system that will help Europe find its way in the 21st century now has 14 satellites in orbit after today’s double launch.

Galileos 13 and 14 lifted off together at 08:48 GMT (10:48 CEST, 05:48 local time) atop a Soyuz rocket from French Guiana.
This seventh Galileo launch went by the book: the first three Soyuz stages placed the satellites safely into low orbit, after which their Fregat upper stage hauled them the rest of the way into their target medium-altitude orbit.
The twin Galileos were deployed into orbit close to 23,522 km altitude, inclined 57.394 degrees to the equator, 3 hours and 48 minutes after liftoff. The coming days will see a careful sequence of orbital fine-tuning to bring them to their final working orbit, followed by a testing phase so that they can join the working constellation later this year.“Today’s textbook launch has added two more satellites to what has become Europe’s largest satellite constellation,” commented Jan Woerner, director general of ESA. “It was made possible by the fact that European industry’s manufacturing and testing of Galileo satellites has achieved a steady tempo.”
“Today’s launch brings Europe’s Galileo constellation halfway to completion, in terms of numbers,” remarked Paul Verhoef, ESA’s Director of the Galileo Program and Navigation-related Activities.
“It is also significant as Galileo’s last flight by Soyuz this year before the first launch using a customized Ariane 5 to carry four rather than two satellites each time – which is set to occur this autumn.
“Meanwhile, hard work is proceeding behind the scenes to ensure the worldwide Galileo system, including its far-flung ground stations, is reliable, secure and robust for the start of operational services to users.”
Full video replay of the launch is available here.
The launch was carried out from the purpose-built ELS launch complex at Europe’s Spaceport,. Total payload lift performance was estimated at 1,599 kg.
The flight had an early morning liftoff from the Spaceport – coming at precisely 5:48:43 a.m. French Guiana time. This Arianespace Soyuz mission was performed at the service of the European Commission, which is managing the Galileo program’s ongoing FOC (Full Operational Capability) phase. Design and procurement agent responsibilities have been delegated to the European Space Agency (ESA) on the commission’s behalf.
It is during the FOC phase that the Galileo network’s complete operational and ground infrastructure will be deployed. Today’s Soyuz mission — designated Flight VS15 — was Arianespace’s fifth overall carrying FOC spacecraft in sets of two. It follows one launch in 2014 (VS09), then three performed last year (VS11, VS12 and VS13). The medium-lift workhorse also lofted a total of four satellites in the program’s IOV (in-orbit validation) phase in 2011 and 2012.
The satellites orbited today — named “DanielÄ—” and “Alizée” after winners of a European Commission-organized painting competition for children — are the 13th and 14th Galileo spacecraft overall to be orbited by Arianespace.
The spacecraft’s onboard payloads were supplied by UK-based Surrey Satellite Technology Limited (SSTL) — a company 99-percent owned by Airbus Defense and Space, which is an Arianespace shareholder, as well.
Israël acknowledged others that contributed to this latest Arianespace success, including State Space Corporation Roscomos and Russia’s industrial partners involved in the production and operation of Soyuz; along with the European support companies; the French CNES space agency; the ground contractors in French Guiana and Arianespace’s own teams.
Arianespace will conduct another launch for Galileo’s FOC phase later in 2016 — this time using an Ariane 5 and its heavy-lift capability to orbit a four-satellite payload. Two additional launches of the heavy-lift workhorse in 2017-2018 will bring total Galileo deployments to 26 spacecraft.

Engineers Just Smashed the Record for Fast Wireless Data Transmission

As reported by GismodoLike the idea downloading the contents of a DVD in less then 10 seconds without a cable in sight? That’s exactly what a team of German engineers can do, having broken the record for wireless data transmission using terrestrial radio signals.

A team of researchers from the Fraunhofer Institute for Applied Solid State Physics claims to have beaten the previous record for beaming data in this way by a factor of 10. To achieve the feat, they transmitted data on signals in the 71–76 GHz radio frequency band—which is usually used for terrestrial and satellite broadcasting.
But to squeeze in that amount of data requires an impressive signal-to-noise ratio, to avoid having to waste bandwidth on error-correction. So the team built a system of ultra-efficient transmitters and receivers. The transmitters are based on semiconductor chips made gallium-nitride, which provide a high-power signal that’s transmitted from a focused parabolic antenna.
The team beamed the signals between a 45-story tower in central Cologne and the Space Observation Radar in Wachtberg, 23 miles away. At the receiver, the researchers used special low-noise amplifiers built using indium-gallium-arsenide transistors. Their sensitivity allows them to detect incredibly weak signals.
The resulting speed of 6 gigabits per second has pretty obvious application. The researchers points out that a single transmission beam could be used to supply as many as 250 internet connections running at 24 meagabits per second to sites where it’s impossible to run a wired connection. While you might immediately think such a system would be best suited to, say, disaster zones, the researchers reckon it could even prove a “cost-effective replacement for deployment of optical fiber.”

New Space Station Orbiting The Moon By 2020 Announced

As reported by FuturologyOrbital ATK has unveiled a practical new proposal to build a near term man-tended outpost in lunar orbit that could launch by 2020 and be operational in time for a lunar link-up with NASA’s Orion crew module during its maiden mission, when American astronauts finally return to the Moon’s vicinity in 2021 – thus advancing America’s next giant leap in human exploration of deep space.

The intrepid offer by Orbital could be carried out rather quickly because it utilizes an evolved version of the company’s already proven commercial Cygnus space station resupply freighter as “the building block … in cislunar space,” said Frank DeMauro, Orbital ATK Vice President for Human Spaceflight Systems, in an exclusive interview with Universe Today. See an artist concept in the lead image.
“Our Cygnus spacecraft is the building block to become a vehicle for exploration beyond low Earth orbit,” Orbital ATK’s Frank DeMauro told Universe Today.
“We are all about supporting NASA’s Mission to Mars. We feel that getting experience in cislunar space is critical to the buildup of the capabilities to go to Mars.”
NASA’s agency wide goal is to send astronauts on a ‘Journey to Mars’ in the 2030s – and expeditions to cislunar space in the 2020s serve as the vital ‘proving ground’ to fully develop, test out and validate the robustness of crucial technologies upon which the astronauts lives will depend on later Red Planet missions lasting some 2 to 3 years.
Orbital ATK’s lunar-orbit outpost proposal was announced at an official hearing of the US House of Representatives Subcommittee on Space on Wednesday, May 18, by former NASA Astronaut and Orbital ATK President of the Space Systems Group, Frank Culbertson.
“A lunar-orbit habitat will extend America’s leadership in space to the cislunar domain,” said Orbital ATK President of the Space Systems Group, Frank Culbertson.
“A robust program to build, launch and operate this initial outpost would be built on NASA’s and our international partners’ experience gained in long-duration human space flight on the International Space Station and would make use of the agency’s new Space Launch System (SLS) and Orion deep-space transportation system.”
The idea is to assemble an initial crew-tended habitat with pressurized work and living volume for the astronauts based on a Cygnus derived vehicle, and have it pre-positioned and functioning in lunar-orbit by 2020.
As envisioned by Orbital ATK, the habitat would be visited during NASA’s first manned mission of SLS and Orion to the Moon known as Exploration Mission-2 (EM-2).
The three week long EM-2 lunar test flight could launch as early as August 2021 – if sufficient funding is available.
The goals of EM-2 and following missions could be significantly broadened via docking with a lunar outpost. And Orion mission durations could be extended to 60 days.
NASA hopes to achieve a launch cadence for Orion/SLS of perhaps once per year.
Therefore autonomy and crew tended capability has to be built in to the lunar habitat right from the start – since crew visits would account for only a fraction of its time but enable vastly expanded science and exploration capabilities.

Uber Shows Off its First Self-Driving Car

As reported by Engadget: Uber's foray into the world of self-driving vehicles will become a lot more visible in the coming weeks after the company confirmed its first autonomous car will officially hit the streets of Pittsburgh. The prototype -- a hybrid Ford Fusion -- will assist the company in collecting mapping data while putting its self-driving capabilities to the test. Uber's Advanced Technologies Center (ATC), which is headquartered in the city, has equipped the car with a variety of sensors including radar, laser scanner and high-resolution cameras, but a human rider will be present at all times.

While this isn't the first time we've heard about Uber's prototype -- it was spotted cruising the city's streets by the Pittsburgh Business Times last year -- it is the first time the company has publicly shared news of its plans. In a blog post, Uber says that the development of its self-driving technology will mean "less congestion, more affordable and accessible transportation, and far fewer lives lost in car accidents."

Uber has already gained permission from local authorities to test its car and will use the road miles to ensure it can deal with pedestrians, cyclists and other drivers. It thinks Pittsburgh's streets will also provide the right environment for its vehicle to learn from, with its differing road types, traffic models and weather conditions. It also helps that Carnegie Mellon is on the doorstep, allowing the company to gather experience from engineers who have already built advanced autonomous robots and Mars rovers.

The end game, it appears, is to be one of the first to market with a fleet of for-hire vehicles. General Motors will invest $500 million in Lyft to help beat Uber to the punch and Google is forging ahead with the development of its own driverless car with the idea to spin the business off into an autonomous taxi service. Each entrant needs thousands of road miles before their vehicles are ready to take passengers, suggesting you'll see many more driverless prototypes in the wild in the months ahead.
