Sandia National Laboratories’ four-channel, silicon photonic single-sideband modulator chip, measuring 8 millimeters on each side and marked with a green Sandia thunderbird logo, sits inside packaging that incorporates optical fibers, wire bonds, and ceramic pins. Credit: Craig Fritz, Sandia National Laboratories ==================================================================== A milestone in quantum sensing is drawing closer, promising exquisitely accurate, GPS-free navigation. Peel apart a smartphone, fitness tracker or virtual reality headset, and inside you’ll find a tiny motion sensor tracking its position and movement. Bigger, more expensive versions of the same technology, about the size of a grapefruit and a thousand times more accurate, help navigate...

I have a full grown, 80 lb. Black Lab and 3 odd shaped acres.He's stud, rambunctious and a handful for my 100 lb. wife.I've seen an ad about a GPS system and research shows me they're not new and with a number of variable features.If anyone has any pragmatic information, I'd like it.

The Global Positioning System runs the modern world.… But it is under daily attack. This year alone, researchers say, more than 60,000 commercial flights have been hit by bogus GPS signals, which can confuse pilots.… The American GPS network that was once the gold standard is at risk of becoming a relic as Chinese, Russian and European systems modernize.

Opinion The scientific community celebrated April 14 as World Quantum Day to raise awareness of quantum science’s impact across diverse fields The world of science is on the cusp of a transformative era driven by the burgeoning field of quantum technology. Quantum science is founded on several key principles that underpin the behaviour of particles and systems at the quantum scale. The term “quantum scale” refers to the realm of physics that deals with phenomena occurring at very small scales, typically at the level of atoms, subatomic particles and fundamental particles. It encompasses the principles of quantum mechanics, which govern...

Every once in a while, a revolutionary product comes along that changes everything. Or so said Steve Jobs when he announced iPhone in 2007.But I’m talking about a different revolutionary product. A foundational product that forever changed how everyone on this planet gets to where they need to be. Today, I’d like to tell you about the Etak Navigator, a truly revolutionary product and the world’s first practical vehicle navigation system.Here’s a picture of it:At the time, it was considered out-of-this-world. This is what Silicon Valley’s San Jose Mercury News said about it:The Etak Navigator launched 39 years (!) ago...

GPS is being blocked across swathes of Israel in order to disrupt missiles and drones, as tensions rise with Iran. Iran has vowed to respond after a strike on its consulate building in Syria on Monday - which Israel was widely believed to be behind - killed 13 people, including a senior general. The Israel Defense Forces (IDF) also announced it was halting all leave for soldiers serving with combat units. It comes a day after reservists were called up to bolster air defence units. Israeli authorities seem to believe an Iranian response is imminent and could come as soon...

Commercial air crews are reporting something “unthinkable” in the skies above the Middle East: novel “spoofing” attacks have caused navigation systems to fail in dozens of incidents since September. In late September, multiple commercial flights near Iran went astray after navigation systems went blind. The planes first received spoofed GPS signals, meaning signals designed to fool planes’ systems into thinking they are flying miles away from their real location. One of the aircraft almost flew into Iranian airspace without permission. Since then, air crews discussing the problem online have said it’s only gotten worse, and experts are racing to establish...

I am appearing on The Space Show today at 12:30 pm EST with Pete Wilhelm. Pete worked at the Naval Research Lab from 1959-2014 and knew many space pioneers including Wernher von Braun and Elon Musk. He has great stories. Listen live on the website or download a podcast.

Two people and their dog were found dead at Banff National Park on Saturday after a grizzly bear attack. A GPS device alerted Parks Canada on Friday night, indicating a bear attack was happening within the Red Deer River Valley region west of Ya Ha Tinda Ranch in Canada’s Banff National Park... Due to poor weather conditions, an emergency team reportedly could not fly to the location via helicopter, so they traveled by ground during the night. When the team arrived at the scene, they reportedly found two individuals who were deceased and ... The victim’s identities have not been...

A North Carolina woman is suing Google after her husband died after driving off a collapsed bridge while following GPS directions, according to a lawsuit filed this week. Philip Paxson died after driving off "an unmarked, unbarricaded collapsed bridge" on the night of Sept. 30, 2022, in Hickory, his widow, Alicia Paxson, said in the suit filed in Wake County on Tuesday. Paxson was not aware the bridge had collapsed and was following GPS directions from Google, which had not been updated, the lawsuit says.

It’s taken 400 years of scientific discoveries to make it possible for anyone to find his location anywhere on the globe using GPS.With the letters GPS, we instantly recognize an innovation that has revolutionized our lives. The concept was born half a century ago in a sweltering room at the Pentagon over Labor Day weekend in 1973.That’s the genesis of the concept for a constellation of platforms orbiting the Earth, transmitting radio signals to determine location. Many years of calculation, experiment, and miniaturization led to the Navigation Signal Timing and Ranging (NAVSTAR) satellites that became known as the Global Positioning...

A 9K33 Osa SAM System is hit by HIMARS about 50 kilometers from the frontlines in Kherson. (Very interesting discussion in comments.)

French police should be able to spy on suspects by remotely activating the camera, microphone and GPS of their phones and other devices, lawmakers agreed late Wednesday. Part of a wider justice reform bill, the spying provision has been attacked by the left and rights defenders as an authoritarian snoopers' charter, though Justice Minister Eric Dupond-Moretti insists it would affect only 'dozens of cases a year'.

After nearly five months of waiting, an alarm activated on Michael Cove’s radio, a sign his study was working. To hunt pythons, an invasive predator in the Florida Keys, Cove and fellow researchers have been strapping GPS collars to opossums and raccoons. When one was eaten by a python in September, researchers programmed the device to notify them from within the snake’s stomach.... According to a ScienceDaily study, the number of raccoons, opossums and bobcats in the Everglades all dropped by at least 87 percent between 1997 and 2012. The same study found that marsh and cottontail rabbits and foxes...

KYIV, Ukraine — Ukrainian officials said they require coordinates provided or confirmed by the United States and its allies for the vast majority of strikes using its advanced U.S.-provided rocket systems, a previously undisclosed practice that reveals a deeper and more operationally active role for the Pentagon in the war. The disclosure, confirmed by three senior Ukrainian officials and a senior U.S. official, comes after months of Kyiv’s forces pounding Russian targets — including headquarters, ammunition depots and barracks — on Ukrainian soil with the U.S.-provided High Mobility Artillery Rocket System, or HIMARS, and other similar precision-guided weapons such as...

It was easy to make jokes last summer when reports surfaced that Google Maps and other navigation systems were wrongly directing people off of Interstate 80 and rerouting drivers through Colorado. Sure, it added eight hours to a trip, but it wasn’t necessarily dangerous. But seven months later, it’s still happening. And in the winter months, it could be deadly. The problem is these navigation apps continue to send the wrong information primarily on or around Interstate 80 in southcentral Wyoming. The Rock Springs area seems to be the hot spot. On one day last month, the Sweetwater County Sheriff’s...

The news item here can be summed up in a limerick: There once was a prez on Nantucket, and he couldn’t get ‘round in a bucket. He rented some cars, and drove under the stars, until each one, a car fire struck it. Okay, so I ain’t Shakespeare. But this really happened. As Fox News reported more prosaically Tuesday, “President Biden’s rented Secret Service vehicles burst into flames in a parking lot Monday, just one day after he left his Nantucket vacation.” Yes, they really called him, whimsically enough, “President Biden,” not the more accurate “Alleged President Biden” or “Ostensible...

President Joe Biden’s Secret Service rental vehicles were part of a large fire just one day after he left from a Nantucket vacation. The Monday fire at the Nantucket Memorial Airport in Massachusetts included five vehicles rented from Hertz that were used to transport the president and his family. “A large car fire involving multiple rental vehicles at Nantucket Memorial Airport is now out. There were no injuries reported but at least four cars sustained significant damage,” the Nantucket Current tweeted in a series of posts alongside videos and pictures of the damage. “The fire was just 40 feet away...

Data was used to help Democrats win elections. Tens of millions of US citizens were given a “COVID-19 decree violation” score as a result of a data harvesting program conducted during the first lockdown by voter analytics firm PredictWise. “These Covid-19 decree violation scores were calculated by analyzing nearly two billion global positioning system (GPS) pings to get “real-time, ultra-granular locations patterns.” People who were “on the go more often than their neighbors” were given a high Covid-19 decree violation score while those who mostly or always stayed at home were given a low Covid-19 decree violation score,” writes Reclaim...
