  • Weekly Takeaways-January 24,2023

    The Last 500 Feet Recently NASA hosted a Position, Navigation, and Timing (PNT) Workshop dedicated to the “last 500 feet.” While GPS and other satellite navigation systems work well on the open road and high seas, they don’t work well in large cities, urban canyons, and inside buildings. And this is where accurate positioning is needed for self-driving cars, flying taxis, and delivery drones. This is the "last 500 feet" problem. One solution: move the PNT signals closer to the ground. Terrestrial beacons can deliver high-power RF signals and be optimally concentrated near traffic lanes. But these beacons require very accurate time synchronization. Last Week's Theme: ...Looking Forward Industry News A flurry of new US government reports were recently released: A Department of Homeland Security (DHS) report on the 33 hour GPS outage at Denver International Airport was finally released, but didn’t explain what caused the outage. A US Government Accountability Office (GAO) report documents the US government's “head in the sand” approach to assessing GPS jamming. A National Science and Technology Council (NSTC) report outlines US government quantum plans and funding. In response to Russia’s satellite hacking the Aerospace Corporation developed a Space Attack Research and Tactic Analysis (SPARTA) framework “to describe the unique threats hackers may pose to systems in space.” NASA also admits that there is a new space race underway. Canada announced a National Quantum Strategy including plans for the QEYSSat quantum satellite. Two new venture funding reports are out: the CB Insights “State of Venture” report (estimates $415.1B in venture funding in 2022) and the Pitchbook “2023 US Venture Capital Outlook” report (estimates $238.3B in venture funding in 2022). The More You Know... The World Economic Forum (WEF) believes that "quantum technology will exponentially accelerate the Fourth Industrial Revolution." But this raises concerns of a Quantum Divide between the 17 countries that are investing in quantum research and the 150 that are not. But the divide is even more stark when you consider that only one country, China, is responsible for half of the global funding in quantum technology. The US has since made quantum and science funding a priority, as have other western countries. These funding efforts are outlined in a National Science and Technology Council (NSTC) report, and inspired the US State Department to set up an Office of the Special Envoy for Critical and Emerging Technology “to lead development of innovative technologies like artificial intelligence and quantum information.”

    Theme of the Week ...Looking Forward GPS has been a cornerstone for the modern world for nearly four decades. All financial transactions, communications, data centers and power grids rely on timing from GPS. And that will continue – GPS and other GNSS systems are critical for global navigation and timing. But there are future needs that they cannot address: 6G networks that require tight synchronization “to make far more efficient use of spectrum." Self-driving cars, flying taxis, and delivery drones cruising effortlessly through large cities. Precise indoor navigation and timing for manufacturing and delivery robots. Position sensors accurate enough for early tsunami and earthquake warning. Weather detection using RF signals delays caused by water vapor in the air. Quantum networks that may one day entangle quantum computers. Accurate, traceable, and verifiable time stamps for financial transactions. A lunar GPS network to support manned missions to the moon. Deep space missions including detection of dark matter. Satellites in tight formation flying for scientific and communication missions. It's 2023 and the future beckons. Last Week's Theme: Looking Back… Industry News The race for broadband-speed 6G networks is underway. China reportedly leads other countries in 6G patents and has over 2M 5G base stations compared to 100,000 in the US. And they will need better synchronization "to coordinate the sharing of frequency bands in real-time, rather than relying on guard time and guard bands (the buffer zones between different chunks of spectrum).” The Q-NEXT quantum research center's recent ​“A Roadmap for Quantum Interconnects” report outlines the research and scientific discoveries needed to develop the technologies for distributing quantum information on a 10- to 15-year timescale. The US $1.7T 2023 spending bill “includes the highest research and development-driving budget in the Pentagon’s history and billions in additional funds to accelerate the military’s adoption of cutting-edge capabilities” The moon also needs its own GPS system, and the Aerospace Corporation and Space Systems Command have ideas. Pitchbook’s 2023 US Venture Capital Outlook noted that fundraising hit records in 2022, “surpassing 2021's figure in just three quarters…Dry powder remains extremely high, but dealmaking has continuously slowed on a quarterly basis throughout the year.” Meanwhile The Quantum Insider prepared their assessment of quantum investments in 2022 and quantum predictions for 2023. If you suffered from travel delays over the holidays, there is hope that future quantum computers could one day help in “untangling operational disruptions.” Conferences Time and Money Conference, January 17, New York, New York Photonics West and Quantum West, January 28 - February 2, San Francisco, CA Workshop on Synchronization and Timing Systems, March 13 - 16, Vancouver, Canada Satellite 2023, March 13 - 16, Washington DC Space Symposium, April 17 - 20, Colorado Springs, CO The More You Know... Recently Russia has expanded their jamming of GPS into Russia and Moscow in the light of drone attacks. This is wreaking havoc with commercial flights and portends further escalation as the conflict drags on. When Russia originally invaded, they also expected easy disruption of Ukraine's communication networks. But they didn’t count on the resiliency of commercial satellite systems. Starlink, in particular, has been resilient to Russia’s cyber-attacks with their “ability to quickly update the system’s software.” And threats of attacks using anti-satellite missiles “would also be a lot less useful against a constellation like Starlink than against older systems. Knocking out a single Starlink would achieve more or less nothing. If you want to damage the space-based bit of the system, you need to get rid of lots of them.”

  • Weekly Takeaways-December 23,2022

    Theme of the Week The North Pole needs Quantum Scientists Santa has a problem. To efficiently deliver presents to 200 million homes in one day requires some serious planning! This is the traveling salesman problem. Let’s say the naughty-to-nice threshold is really high, so only four children get presents. Even with only four stops there are still 28 different routes Santa can take. Calculating an optimal path gets exponentially harder as more stops are added. This is beyond the capability of today’s computers, but fortunately for Santa (and other delivery companies) this might one day be solved by future quantum computers. Santa also needs a very precise clock - after all, a few microsecond error leads to missed targets when traveling at 1560 km per second. Good luck Santa! Last Week's Theme: Did You Know? Industry News A new US Department of Defense (DoDO report outlines concerns about China’s ability to “conduct jamming and anti-jamming operations against…Global Positioning System (GPS) satellite systems during force-on-force exercises,” noting that China “has also launched multiple anti-satellite (ASAT) missiles that are able to destroy satellites and developed mobile jammer to deny SATCOM and GPS.” A DoD official also claimed that China is expected to develop an ASAT weapon "targeting Geosynchronous Earth orbit (GEO) systems,” and “extensive electronic warfare capabilities intended to deny satellite communications, radar systems, and GPS navigation, and it’s developing laser weapons to dazzle sensors and potentially destroy satellite components.” The Quantum Computing Cybersecurity Preparedness Act was signed into law. It will help prepare agencies and companies develop “encryption strong enough to resist attacks from quantum computers developed in the future.” New reports emerged of GPS signals being disrupted in Russian cities as a response to drone attacks, “suspected Russian hackers lurking inside a U.S. satellite network,” and cyber attacks of energy grids. Q-NEXT, a U.S. Department of Energy (DOE) National Quantum Information Science Research Center, released “A Roadmap for Quantum Interconnects.” Conferences Time and Money Conference, January 17, New York, New York Photonics West and Quantum West, January 28 - February 2, San Francisco, CA Workshop on Synchronization and Timing Systems, March 13 - 16, Vancouver, Canada Satellite 2023, March 13 - 16, Washington DC Space Symposium, April 17 - 20, Colorado Springs, CO The More You Know... In addition to the solving problems like the efficient delivery of gifts, Inside Quantum Technology has explored other interesting quantum technology use cases for: Loans. mortgages, and the world of finance The automotive industry Detecting cancerous tumors Rooting out deepfakes The space industry Physicists even "purportedly created the first-ever wormhole" with a quantum computer. But before you get excited "this isn't a bona fide traversable wormhole." But as we assess the future that quantum technology could unlock, it is worth thinking about “what is meaningful for society in the long term.”
