• Spacecraft Speedometer promises precise satellite positioning, no GPS required
    www.techspot.com
    Forward-looking: Traffic in low Earth orbit has surged in recent years. The growing number of satellites is now pushing scientists to develop new management and tracking solutions, as GPS and ground-based stations can sometimes be unreliable or unavailable. The Los Alamos National Laboratory has introduced the "Spacecraft Speedometer," a novel technology for tracking satellites in low Earth orbit. This compact, resource-efficient device can precisely measure a satellite's speed as it orbits the planet. Researchers believe it could also serve as a tracking solution for deep-space missions.Designed to provide onboard, real-time velocity measurements, the Spacecraft Speedometer enables space agencies and commercial operators to predict satellite positions and execute orbital maneuvers to avoid collisions with other satellites or space debris.Los Alamos developed the system in response to increasing congestion in LEO, where the number of active satellites surged from 2,287 in 2019 to over 10,000 in 2024. With the rise of mega-constellations, traffic management challenges are expected to grow even more severe.Current methods for tracking satellite speed and position rely on GPS or ground-based radars. While GPS works when a satellite has a functioning receiver, it can become unreliable during solar storms. Ground stations, meanwhile, can only track orbiting objects intermittently sometimes just once every few hours or days.The newly introduced Spacecraft Speedometer offers a more reliable alternative to both systems, providing continuous velocity data even during extreme space weather. Researchers also suggest it could track orbital insertions in other planetary atmospheres, monitor local space environments, and measure dangerous particle charging levels. // Related StoriesThe device achieves these capabilities through its twin laminated plasma spectrometers, which measure charged particles (ions and electrons) striking the front and rear of a spacecraft. Los Alamos researchers compare this process to a car driving through heavy rain: more raindrops hit the front windshield than the rear. By analyzing this difference, the Spacecraft Speedometer can determine a satellite's speed and position in real time.

    www.digitaltrends.com
    Nvidia is working on a computer that combines AI, super-computing and quantum in one machine to rule them all. This will be born in the newly revealed Nvidia Accelerated Quantum Research Center (NVAQC).Nvidia made the major announcement for quantum computing fans from its GTC Global AI Conference today.Recommended VideosOne of the issues for quantum computing has been scaling. This new center could help to tackle that problem right away for next-generation computing, soon.Get your weekly teardown of the tech behind PC gaming A major stumbling block for quantum computing is sorting through the qubit errors that naturally occur. As qubits interact with their surrounding this creates noise which needs to be isolated. This is done by processing outputs from repeated measurements of these noisy qubits.The process of identifying, tracking and correcting qubit errors is called decoding. This is where AI and supercomputing come in, as these combined could help to accelerate decoding the goal of this new NVAQC facility.While Nvidia is creating the space for this research to take place, it is not going it alone. Quantum computing innovators will come together to work on the problems, including Quantinuum, QuEra and Quantum Machines.Academic partners are also taking part with partners in Harvard Quantum Initiative and the Engineering Quantum Systems group at the MIT Center for Quantum Engineering.The NVAQC draws on much-needed and long-sought-after tools for scaling quantum computing to next-generation devices, said Tim Costa, senior director of computer-aided engineering, quantum and CUDA-X at NVIDIA.He said: The center will be a place for large-scale simulations of quantum algorithms and hardware, tight integration of quantum processors, and both training and deployment of AI models for quantum.Nvidia gave the statement: Building on tools like NVIDIA DGX Quantum a reference architecture for integrating quantum and classical hardware and CUDA-Q, the NVAQC is set to be an epicenter for next-generation developments in quantum computing, seeding the evolution of qubits into impactful quantum computers.Editors Recommendations

  • How Auracast is helping the hard of hearing at Sydneys iconic Opera House
    www.digitaltrends.com
    Weve been talking up the possibilities of Bluetooths broadcast audio tech known as Auracast for some time now. And while weve been seeing it emerge more recently in devices such as Bluetooth speakers and headphones, in a world-first the wireless audio innovation has been installed in the iconic Sydney Opera House to help those with hearing needs rediscover their love for live music.Youd be forgiven if you havent heard of Auracast, but the technology, developed by Bluetooths governing body, the Bluetooth Special Interest Group (SIG), in a nutshell, uses Bluetooths super-efficient Low Energy (LE) Audio standard to allow high-quality audio to be broadcast from a Auracast-enabled transmitting devices to Auracast-enabled audio receivers in this case, hearing aids and headphones. Users can tune into the specific broadcasts using an app or other interface.Recommended VideosWeve checked out the technology first-hand at CES over the years, and it has broad application scenarios, including allowing airport visitors to tune into their specific flights gate announcements through their headphones, and even bars and restaurants could use it to allow sports fans to choose the sound they want if there are multiple games being played on several TVs.An Auracast transmitter installed on a TV broadcasts its audio to compatible Auracast devices. Derek Malcolm / Digital TrendsThe Sydney Opera House, in collaboration with hearing tech market leaders GN, Hearing Australia, and Australias National Acoustic Laboratories, today has just become the worlds first major cultural institution to install Auracast in its performance areas, which include its Drama Theatre, Playhouse, and Studio venues, with the larger Concert Hall and other rooms likely to follow. Bluetooth LE Audio not only offers low latency and efficient battery use, but allows for excellent sound quality. Combined with Auracast, the protocol can connect to a limitless number of receiving devices.A string quartet performs at the Sydney Opera Houses Auracast launch. GNAuracast is now available for live performances at the Sydney Opera House to allow users with compatible Auracast hearing aids or headphones to enjoy, in an effort to improve inclusion and enjoyment for all. With any luck, this will signal the rest of the world to follow suit and bring the tech to a broader audience.Please enable Javascript to view this contentHearing aid users can face barriers at live performances, with current assistive listening systems such as induction hearing loops optimized for speech, while music can sound distorted and available seating limited to areas with coverage, a press release states. The implementation of Auracast aims to improve the experience.For the Sydney Opera House launch, those without compatible hearing-aid devices were given a pair of Auracast-capable Samsung Galaxy Buds3 Pro to test out the experience. Reps from Samsung, Google, and the Bluetooth SIG were at the launch event, where they showcased Auracast-enabled products that demonstrated how it enhances listening experiences in public spaces and venues, the press release continues.Samsung Galaxy S24 Ultra with the Galaxy Buds3 Pro Andy Boxall / Digital TrendsIts reported that one in five people globally suffer from hearing loss. In the U.S. alone, 1 in 8 people (13%, or 30 million people) ages 12 or older has hearing loss in both ears, according to the National Institute on Deafness and Other Communication Disorders. But options are improving for those who suffer from hearing loss. In 2022, the FDA formally opened the market for over-the-counter (OTC) hearing aids, making them available to mild-to-moderate sufferers without a prescription or hearing exam. Most recently, Apple added hearing aid features to its AirPods Pro 2 earbuds.Auracast has the ability to drive things ever further for those with hearing-related issues.We are at the forefront of bringing Auracast to hearing aid wearers so they can easily connect to and enjoy great sound no matter where they are, said Peter Karlstromer, CEO of GN. We are very proud to collaborate with the Sydney Opera House, National Acoustic Laboratories and Hearing Australia to enable Auracast and inclusive performances at this iconic venue we hope it will encourage more to follow suit and enter the next era of connectivity.Editors RecommendationsHouse of Marleys new headphones look to provide powerful sound with a purpose

  • Rather than lower rates, Arkansas jail simply cancels all inmate phone calls

    INfeasible Rather than lower rates, Arkansas jail simply cancels all inmate phone calls One angry sheriff takes on the FCC. Nate Anderson Mar 18, 2025 4:08 pm | 26 Credit: Getty Images Credit: Getty Images Story textSizeSmallStandardLargeWidth *StandardWideLinksStandardOrange* Subscribers only Learn moreSheriff John Montgomery of Baxter County, Arkansas, isn't going to take it anymoreif by "it" you mean "having to offer lower phone call rates to incarcerated inmates." Noting that such phone calls are "not required to be provided by law," Montgomery is ending all inmate phone calls on March 30, 2025.The cause of Montgomery's wrath, and of his March 30 date, is the Federal Communications Commission, which set an April 1, 2025, deadline for smaller jails to lower the obscene rates of inmate phone calls. (Larger jails had to comply in January.) According to the FCC, 15-minute phone calls to inmates could run as much as $12.10 in these smaller jails. The Commission now demands that such calls cost no more than $1.35. (You can read the new rate schedule here.)The rates are high in part because extra security is required for inmate communications services, but the system had also become a way for local agencies to make money by charging vendors a "site commission payment." In this model, vendors might be selected based less on what was good for security and for inmate families and more on how much cash the vendor could funnel to the jail. FCC Commissioner Geoffrey Starks even referred to these payments as "kickbacks."In 2024, the FCC finally took a hatchet to this entire system. The Commission slashed the fees paid by inmates, it banned all sorts of nickel-and-dime fees that had crept into the process, and it prohibited communications vendors from making "site commission" payments to jails.Now, with compliance coming into view, agencies like the Baxter County Sheriff's Office are expressing their displeasureand taking it out on the inmates. Montgomery recently announced that he is canceling all inmate phone calls. He knows that this will "place a hardship on families," as his press release puts it, but he places all the blame on the federal government, which is name-checked three times in four paragraphs.If "the Federal Communications Commission reverses their adverse regulations," Montgomery said, "the Baxter County Sheriff's Office will revisit the feasibility of reimplementing the inmate phone system."One might expect this view to generate some sympathy in the MAGA-fied halls of FCC HQ. But the Commission's two Republicans actually voted in favor of the rate control order last year. Current FCC Chair Brendan Carr even agreed that inmate phone calls in American prisons were often "excessive" and that the private operators behind these systems represented a "market failure." He then voted for straight-up, old-school price caps.In fact, Carr went on to offer a robust defense of inmate calling, saying: "[I often] heard from families who experienced firsthand the difficulties of maintaining contact with their incarcerated loved ones. I also heard from formerly incarcerated individuals who underscored the decline in mental and emotional health that can result from a lack of external communications. Beyond that, studies have repeatedly shown that increased communication between incarcerated people and their families, friends, and other outside resources helps reduce recidivism rates."So Montgomery may not get this decision reversed easily. (On the other hand, Carr did just launch a "Delete! Delete! Delete!" initiative focused on cutting regulations, so who knows.)Baxter County claims that the FCC decision means that phone services are no longer "feasible." In 2018, however, when Baxter County wanted to expand its jail and didn't have the cash, officials found a way to make it feasible by asking voters to approve a 1-cent sales tax collected between April and September of that year. (You can even watch a time-lapse video of the jail expansion being built.) Feasibility, it turns out, is often in the eye of the beholder.Montgomery did say that he would add some additional in-person visiting hours at the jail to compensate for the lack of phone calls, and last week his office posted the new schedule. But as positive as in-person contact can be, in a busy world it is still nice to have the option of a reasonably priced phone callyou know, the kind that's "feasible" to offer at most other jails in the US.Nate AndersonDeputy EditorNate AndersonDeputy Editor Nate is the deputy editor at Ars Technica.

  • Gemini gets new coding and writing tools, plus AI-generated podcasts
    arstechnica.com
    Collaborate with robots Gemini gets new coding and writing tools, plus AI-generated podcasts Gemini is absorbing features from one of Google's coolest AI products. Ryan Whitwam Mar 18, 2025 3:40 pm | 7 Credit: Google Credit: Google Story textSizeSmallStandardLargeWidth *StandardWideLinksStandardOrange* Subscribers only Learn moreOn the heels of its release of new Gemini models last week, Google has announced a pair of new features for its flagship AI product. Starting today, Gemini has a new Canvas feature that lets you draft, edit, and refine documents or code. Gemini is also getting Audio Overviews, a neat capability that first appeared in the company's NotebookLM product, but it's getting even more useful as part of Gemini.Canvas is similar (confusingly) to the OpenAI product of the same name. Canvas is available in the Gemini prompt bar on the web and mobile app. Simply upload a document and tell Gemini what you need to do with it. In Google's example, the user asks for a speech based on a PDF containing class notes. And just like that, Gemini spits out a document.Canvas lets you refine the AI-generated documents right inside Gemini. The writing tools available across the Google ecosystem, with options like suggested edits and different tones, are available inside the Gemini-based editor. If you want to do more edits or collaborate with others, you can export the document to Google Docs with a single click.Canvas is also adept at coding. Just ask, and Canvas can generate prototype web apps, Python scripts, HTML, and more. You can ask Gemini about the code, make alterations, and even preview your results in real time inside Gemini as you (or the AI) make changes.Audio Overviews is not actually a new featureit debuted last year as part of a Google product called NotebookLM. The gist is that you upload some documents, and the AI assimilates the data to generate a conversation between two people who don't exist. Google likens this to a podcast-style discussion, and that's a fair description of what you get. Sometimes, the fake hosts even give the fake podcast a name. Gemini Audio Overviews. To use Gemini's Audio Overviews, just upload a document and look for the "Generate Audio Overview" button above the prompt bar. Be warned, creating the audio takes several minutes, even for a relatively small amount of text. This is similar to Audio Overviews in NotebookLM, but the feature has a little more to offer as part of Gemini.Audio Overviews is also integrated with Deep Research, the AI-powered agent that can peruse the Internet on your behalf. Google recently made Deep Research free for limited use, and now you can do more with those reports. When viewing the results of Deep Research (which also take several minutes to create), you'll now be able to generate an Audio Overview from the report.Google says both Canvas and Audio Overviews are available for all users globallyyes, even the free version of Google's AI. However, Audio Overviews only works in English for now. The company promises more languages later.Ryan WhitwamSenior Technology ReporterRyan WhitwamSenior Technology Reporter Ryan Whitwam is a senior technology reporter at Ars Technica, covering the ways Google, AI, and mobile technology continue to change the world.
