Roger Easton, GPS Developer for Satellite Navigation, Dies at 93

As reported by BloombergRoger Easton, one of the lead inventors of the Global Positioning System, the satellite-based navigation technology used by everything from mobile phones to guided missiles, has died. He was 93.  

He died May 8 at his home in Hanover, New Hampshire, according to a statement by the U.S. Naval Research Laboratory in Washington, where he worked for 37 years.

Easton helped create some of the most significant space systems, including Project Vanguard, which in 1958 launched the first solar-powered satellite, and the U.S. Naval Space Surveillance System, which tracked thousands of man-made objects orbiting Earth through a nationwide network of detectors.
His contributions to the Global Positioning System, or GPS, grew out of his earlier work and were the source of his greatest fame. The system today involves two dozen orbiting satellites, called Navstar, that send out precisely timed signals. The transmissions are detected by mobile phones, aircraft, cars and ships at sea to enable accurate navigation.
Originally deployed for the military, GPS has come to encompass entire industries involving navigation, surveying, communication and time-keeping. Services related to the technology generate annual revenue of $150 billion to $270 billion globally, according to a 2013 study by Oxford, U.K.- based Oxera Consulting Ltd.
At the Navy lab starting in 1964, Easton developed the Timation system (named for time-navigation) which featured satellites carrying highly accurate clocks in orbit.
Other Contributors
Easton isn't the only scientist credited for the development of GPS. Ivan Getting, a Raytheon Manufacturing Co. scientist who envisioned a version of GPS in the 1950s, and Bradford Parkinson, an Air Force colonel who developed it in the 1970s, were both inducted into the National Inventors Hall of Fame for their contributions to satellite-based navigation.
Easton held 11 U.S. patents including patent 3,789,409 for “navigation systems using satellites and passive ranging techniques” for timation, according to the Navy lab statement.
Roger Lee Easton was born on April 30, 1921, in Craftsbury, Vermont, to Frank Birch Easton, a physician, and Della Donnocker Easton, a homemaker. He graduated from the Craftsbury Academy in 1939 and Middlebury College in Vermont in 1943. Later that year, after one semester at the University of Michigan, he joined the Navy lab.
His initial work was on radar beacons and instrument landing systems. In the 1950s, at Whites Sands Proving Grounds in New Mexico, he was involved in rocket experiments, according to the Navy lab’s statement. He also helped coordinate tracking of Sputnik after the Soviet Union launched the world’s first satellite in 1957.
Lab Retirement
In 1980, Easton retired as head of the Space Applications Branch at the lab.
He moved to Canaan, New Hampshire, and served two terms in the state legislature. In 1986, he ran in the Republican gubernatorial primary, focusing on his opposition to the Seabrook Station nuclear power plant, then under construction.
“The only thing worse than losing would be winning,” he told his family, according to the statement.
In 2004, President George W. Bush presented him with the National Medal of Technology. In 2010, he was inducted into the National Inventors Hall of Fame in Alexandria, Virginia.
Survivors include his wife of 68 years, the former Barbara Coulter; a daughter, Ruth Easton; two sons, Roger Easton Jr. and Richard Easton, and five grandchildren, according to the Navy lab statement.

Solar Roadways Project Blows Past $1M Crowdfunding Goal

As reported by ComputerWorld: A project to develop solar power-generating panels that can snap together and form roadways and other surfaces has far exceeded its $1 million crowdsourcing goal.

With three days left to go, Solar Roadways has attracted more than 35.000 donors who've shelled out more than $1.5 million toward the project.

The Solar Roadways Indiegogo crowdfunding project even surpassed the previous record holder for the most Indiegogo contributors; that record had been held by Matthew Inman (The Oatmeal), whose project was to create a museum for Nikola Tesla (33,000 funders).

The Sagle, Idaho-based Solar Roadways company founders, Scott and Julie Brusaw, believe that if deployed on most roadways their technology has the potential to generate three times more electricity than is now used in the U.S.

The hexagonal panels can melt snow and ice to keep road surfaces safe and have LED lights embedded in them that can be used to reconfigure traffic patterns and issue warnings to drivers.

The Solar Roadway panels are made up of four layers. There's a half-inch thick glass surface, followed by a layer of LED lights, an electronic support structure (circuit board) and a base layer made of recyclable materials.

Solar Roadways prototypes have already received federal funding, and the Brusaws now hope to use the crowdsourcing money to ramp up production.



German Scientists Successfully Test Brain-Controlled Aircraft

As reported by Aerospace TechnologyScientists from the Institute for Flight System Dynamics at Technical University of Munich (TUM), Germany have demonstrated the feasibility of flying a brain-controlled aircraft.


Led by professor Florian Holzapfel, the team is researching ways that brain-controlled flight works in the EU-funded project 'Brainflight'.
TUM project head Tim Fricke said a long-term vision of the project is to make flying accessible to more people.
"With brain control, flying, in itself, could become easier," Fricke said. "This would reduce the workload of pilots and thereby increase safety.
"In addition, pilots would have more freedom of movement to manage other manual tasks in the cockpit."
To facilitate humans and machines communication, brain waves of the pilots are measured with the help of electroencephalography (EEG) electrodes connected to a cap.
An algorithm developed by Team Physiological Parameters for Adaptation (PhyPA) of the Technische Universität Berlin (TU Berlin) allows the program to decipher electrical potentials and converts them to useful control commands.
However, the brain-computer interface recognizes only the very clearly defined electrical brain impulses required for control.
"With brain control, flying could become easier. This would reduce the workload of pilots and increase safety."
The German researchers conducted flight simulator tests on seven subjects with varying levels of flight experience, including one person without any practical cockpit experience.
"One of the subjects was able to follow eight out of ten target headings with a deviation of only 10°," Fricke added.
Several of the pilots who participated in the tests managed the landing approach under poor visibility, while one test pilot even landed within only few meters of the center-line.
Following the tests, scientists are now studying how the requirements for the control system and flight dynamics have to be altered to accommodate the new control method.
During general flights, pilots feel resistance in steering and must apply significant force when the loads induced on the aircraft become too large.
As this feedback is missing in brain control, researchers are looking for alternative methods of feedback to signal when the envelope is pushed too hard.

NASA's New Mega-Rocket, Orion Capsule on Track for Future Test Flights

As reported by Space.comA new era of space exploration — supported by a history-making new mega-rocket and a spacecraft designed to deliver humans into deep space — could be on the horizon for NASA.  

The space agency is gearing up to build the largest and most powerful rocket in history. The huge launcher, called the Space Launch System (SLS), will move a new spacecraft dubbed Orion, designed to send up to four astronauts farther into the solar system than ever before. A short list of destinations includes the moon, nearby asteroids and, eventually, Mars.

Everyone is looking forward to 2021, the year when the first manned launch will occur. But before that happens, the rocket and spacecraft will have to pass a number of tests. [NASA's Space Launch System Rocket in Pictures]

SpaceX Unveils Manned Dragon ‘Space Taxi’

As reported by Universe TodaySpaceX CEO, founder and chief designer Elon Musk is set to unveil the manned version of his firms commercial Dragon spaceship later this week, setting in motion an effort that he hopes will soon restore America’s capability to launch US astronauts to low Earth orbit and the International Space Station (ISS) by 2017.


Musk will personally introduce SpaceX’s ‘Space Taxi’ dubbed ‘Dragon V2’ at what amounts to sort of a world premiere event on May 29 at the company’s headquarters in Hawthorne, CA, according to an official announcement this evening (May 27) from SpaceX.
“SpaceX’s new Dragon V2 spacecraft is a next generation spacecraft designed to carry astronauts into space,” according to the SpaceX statement.

The manned Dragon will launch atop the powerful SpaceX Falcon 9 v1.1 rocket from a SpaceX pad on the Florida Space Coast.

Dragon was initially developed as a commercial unmanned resupply freighter to deliver 20,000 kg (44,000 pounds) of supplies and science experiments to the ISS under a $1.6 Billion Commercial Resupply Services (CRS) contract with NASA during a dozen Dragon cargo spacecraft flights through 2016.

Musk is making good on a recent comment he posted to twitter on April 29, with respect to the continuing fallout from the deadly crisis in Ukraine which has resulted in some US economic sanctions imposed against Russia, that now potentially threaten US access to the ISS in a boomerang action from the Russian government:
“Sounds like this might be a good time to unveil the new Dragon Mk 2 spaceship that @SpaceX has been working on with @NASA. No trampoline needed,” Musk tweeted.
“Cover drops on May 29. Actual flight design hardware of crew Dragon, not a mockup,” Musk added.

The ‘Dragon V2’ is an upgraded, man rated version of the unmanned spaceship that can carry a mix of cargo and up to a seven crewmembers to the ISS.

Dragon is among a trio of US private sector manned spaceships being developed with seed money from NASA’s Commercial Crew Program in a public/private partnership to develop a next-generation crew transportation vehicle to ferry astronauts to and from the ISS by 2017 – a capability totally lost following the space shuttle’s forced retirement in 2011.

Since that day, US astronauts have been totally dependent on the Russian Soyuz capsules for ferry rides to orbit and back.

The Boeing CST-100 and Sierra Nevada Dream Chaser ‘space taxis’ are also vying for funding in the next round of contracts to be awarded by NASA around late summer 2014.
All three company’s have been making excellent progress in meeting their NASA mandated milestones in the current contract period known as Commercial Crew Integrated Capability initiative (CCiCAP) under the auspices of NASA’s Commercial Crew Program.

However, US progress getting the space taxis actually built and flying has been repeatedly stifled by the US Congress who have severely cut NASA’s budget request for the Commercial Crew Program by about half each year. Thus forcing NASA to delay the first manned orbital test flights by at least 18 months from 2015 to 2017.

The situation with regard to US dependency on Russian rocketry to reach the ISS has always been awkward.

But it finally took on new found importance and urgency from politicos in Washington, DC, since the ongoing crisis in Ukraine this year exposed US vulnerability in a wide range of space endeavors affecting not just astronaut rides to the ISS but also the launch of the most critical US national security surveillance satellites essential to US defense.

US space vulnerability became obvious to everyone when Russia’s deputy prime minister, Dmitry Rogozin. who is in charge of space and defense industries, said that US sanctions could “boomerang” against the US space program and that perhaps NASA should “deliver their astronauts to the International Space Station using a trampoline.”

Rogozin also threatened to cut off exports of the Russian made RD-180 rocket engines which power the first stage of the United Launch Alliance (ULA) Atlas V rocket used to launch numerous US National Security spy satellites.

“Moscow is banning Washington from using Russian-made rocket engines, which the US has used to deliver its military satellites into orbit,” Rogozin said at a media briefing held on May 13.

NASA is also a hefty user of the Atlas V for many of the agency’s science and communication satellites like the Curiosity Mars rover, MAVEN Mars orbiter, MMS, Juno Jupiter orbiter and TDRS.

Musk and SpaceX have also filed lawsuits against the US Air Force to legally block the importation of the RD-180 engines by ULA for the Atlas V as a violation of the US economic sanctions.

So overall, US space policy is in a murky and uncertain situation and Musk clearly aims for SpaceX to be a central and significant player in a wide range of US space activities, both manned and unmanned.

The First Driverless Cars Will Be Electric, Thanks to Google & Tesla, And That’s Important

As reported by GigaOmMentioned very briefly, and with far less emphasis than the many descriptions of the tiny size of Google’s new driverless car, is that Google’s new experimental fleet of robotic cars are electric.

That’s important because as one of the leaders of developing the software and artificial intelligence that will move autonomous cars through the streets, Google is now also helping set the path for the hardware of the future industry, and it’s skewing that path toward electric vehicles.  

Google has a long history of tinkering with electric cars. They built up a large fleet of plug-in cars for Google employees to use years ago. The program was called theRechargeIT Initiative and was funded with $10 million. I met one of the leaders of that group at an event over six years ago. Today if you go walk around Google’s campus it’s got one of the largest employee fleets of plug-in hybrid and all-electric cars out there.
Google self-driving car
We already knew that Google was interested in exploring pairing autonomous cars with electric cars. I had heard that Google and Tesla were collaborating on some kind of tech around EVs and robotic cars awhile  back, and both Google and Tesla have confirmed that they’d had discussions, though there were no concrete plans here. The leaders of both companies have big-picture end games to make transportation more sustainable in general. I asked Tesla if they had contributed any work to Google’s recently announced robotic car fleet, and I’ll update this when I hear back.
Electric car company Tesla has also maintained that it wants to do its own autonomous car technology for its cars perhaps by 2016. The first driverless tech in a Tesla car will likely be a mode that is like a very good cruise control — picture auto pilot in a plane. But Tesla’s entire goal is to make its cars cheaper, so likely it would need to build its own system that is much less expensive than the current Google one.

That the two most important companies building autonomous car tech will implement their products in electric cars is a big step for the future of personal transportation and an early important market for getting the next generation of cars off of using oil for a fuel. Will robot cars help push electric cars out there, or vice a versa? I can envision both.
It also just makes sense from a technology perspective. Internal-combustion cars, which have a lot of moving parts and create a lot of heat waste, are far more complex than electric cars. Electric cars are like large gadgets, that (obviously) run on electricity, making them a more natural fit with an all-computer powered car. Tesla CEO Elon Musk even called the internal combustion engine a ridiculous way to make a car at an event recently.

Google’s Next Phase in Driverless Cars: No Brakes or Steering Wheel

As reported by the New York Times: Humans might be the one problem Google can’t solve.

For the past four years, Google has been working on self-driving cars with a mechanism to return control of the steering wheel to the driver in case of emergency. But Google’s brightest minds now say they can’t make that handoff work anytime soon.

Their answer? Take the driver completely out of the driving.

The company has begun building a fleet of 100 experimental electric-powered vehicles that will dispense with all the standard controls found in modern automobiles. The two-seat vehicle looks a bit like the ultracompact Fiat 500 or the Mercedes-Benz Smart car if you take out the steering wheel, gas pedal, brake and gear shift. The only things the driver controls is a red “e-stop” button for panic stops and a separate start button.

The car would be summoned with a smartphone application. It would pick up a passenger and automatically drive to a destination selected on a smartphone app without any human intervention.

Google won’t say if it intends to get into the car manufacturing business or simply supply technology to carmakers, but it says there are plenty of possibilities if it can persuade regulators to allow cars with no drivers. One potential use: driverless taxi cabs.

In an interview at Google’s headquarters here, Sergey Brin, a Google co-founder who is actively involved in the research program, said the company decided to change the car project more than a year ago after an experiment in which Google employees used autonomous vehicles for their normal commutes to work.

There were no crashes. But Google engineers realized that asking a human passenger — who could be reading or daydreaming or even sleeping — to take over in an emergency won’t work.

“We saw stuff that made us a little nervous,” said Christopher Urmson, a former Carnegie Mellon University roboticist who directs the car project at Google.

The vehicles will have electronic sensors that can see about 600 feet in all directions. Despite that, they will have rearview mirrors because they are required by California’s vehicle code, Dr. Urmson said. The front of the car will be made from a foamlike material in case the computer fails and it hits a pedestrian. It looks like a little bubble car from the future, streamlined to run by itself — a big change from the boxy Lexus SUV Google has been retrofitting the last few years with self-driving technology.

The new Google strategy for autonomous cars is a break from many competing vehicle projects. Mercedes, BMW and Volvo have introduced cars that have the ability to travel without driver intervention in limited circumstances — though none completely eliminate the driver.

That feature, which is generally known as Traffic Jam Assist, allows the car to steer and follow another vehicle in stop-and-go highway driving at low speeds. In the Mercedes version, the system disengages itself if the driver takes his hands off the steering wheel for more than 10 seconds.

Volvo said that by 2017 it planned to have the cars in the hands of ordinary consumers for testing in the streets of Gothenburg, Sweden, where the company has its headquarters.

In the interview, Mr. Brin acknowledged those advances, but said they were incremental. “That stuff seems not entirely in keeping with our mission of being transformative,” he said.

The current plan is to conduct pilot tests in California, starting with ferrying Google employees between buildings around its sprawling corporate campus here.

Laws permit autonomous vehicles in California, Nevada and Florida. But those laws have generally been written with the expectation that a human driver would be able to take control in emergencies.

Google executives said the initial prototypes would comply with current California automated-driving regulations, issued on May 20. They will have manual controls for testing on California public roads.

In the future, Google hopes to persuade regulators that the cars can operate safely without driver, steering wheel, brake or accelerator pedal. Those cars would rely entirely on Google sensors and software to control them.

So where might the driverless cars be used besides at Google’s offices?

Last year, Lawrence D. Burns, former vice president for research and development at General Motors and now a Google consultant, led a study at the Earth Institute at Columbia University on transforming personal mobility.

The researchers found that Manhattan’s 13,000 taxis made 470,000 trips a day. Their average speed was 10 to 11 m.p.h., carrying an average of 1.4 passengers per trip with an average wait time of five minutes.

In comparison, the report said, it is possible for a futuristic robot fleet of 9,000 shared automated vehicles hailed by smartphone to match that capacity with a wait time of less than one minute. Assuming a 15 percent profit, the current cost of taxi service would be about $4 per trip mile, while in contrast, it was estimated, a Manhattan-based driverless vehicle fleet would cost about 50 cents per mile.

The report showed similar savings in two other case studies — in Ann Arbor, Mich., and Babcock Ranch, a planned community in Florida.

Google is one of the few companies that could take on a challenge like that, said John J. Leonard, a Massachusetts Institute of Technology roboticist. But he added: “I do not expect there to be driverless taxis in Manhattan in my lifetime.”

Mr. Brin said the change in Google’s car strategy did not mean that the company was giving up on its ultimate goal of transforming modern transportation.

“Obviously it will take time, a long time, but I think it has a lot of potential,” he said. “Self-driving cars have the potential to drive in trains much closer together and, in theory, in the future at much higher speeds.

“There is nothing to say that once you demonstrate the safety, why can’t you go 100 miles per hour?”
