Team develops a real-time photonic processor with picosecond latency for dynamic RF interference

Posted by in categories: health, internet, military, robotics/AI

Radar altimeters are the sole indicators of altitude above a terrain. Spectrally adjacent 5G cellular bands pose significant risks of jamming altimeters and impacting flight landing and takeoff. As wireless technology expands in frequency coverage and utilizes spatial multiplexing, similar detrimental radio-frequency (RF) interference becomes a pressing issue.

To address this interference, RF front ends with exceptionally low latency are crucial for industries like transportation, health care, and the military, where the timeliness of transmitted messages is critical. Future generations of wireless technologies will impose even more stringent latency requirements on RF front-ends due to increased data rate, carrier frequency, and user count.

Additionally, challenges arise from the physical movement of transceivers, resulting in time-variant mixing ratios between interference and signal-of-interest (SOI). This necessitates real-time adaptability in mobile wireless receivers to handle fluctuating interference, particularly when it carries safety-to-life critical information for navigation and autonomous driving, such as aircraft and ground vehicles.

North Korea Unveils New Missile Designed for US Mainland Strike

Posted by in categories: energy, existential risks, military

North Korea claimed to have launched a new solid-fuel, intermediate-range missile with a hypersonic warhead, aiming to test its reliability and maneuverability. The missile, designed to strike U.S. military bases in Guam and Japan, flew approximately 620 miles before landing between the Korean Peninsula and Japan. The test follows a previous claim of successfully testing […] The post North Korea Unveils New Missile Designed for US Mainland…

Space Development Agency awards contracts worth $2.5 billion for missile-tracking satellites

Posted by in categories: military, satellites

WASHINGTON — The Space Development Agency announced Jan. 16 it selected L3Harris, Lockheed Martin and Sierra Space to build and operate 54 satellites equipped with infrared sensors capable of tracking hypersonic missiles in all phases of flight.

The satellites will be part of SDA’s Tranche 2 Tracking Layer, a network of satellites in low orbit 1,000 kilometers above Earth.

The three agreements are worth about $2.5 billion. Each company will produce and operate 18 satellites — the contract awarded to L3Harris is worth $919 million, Lockheed Martin’s is $890 million and Sierra Space’s is $740 million. The contracts include incentives for on-time delivery.

New report calls for DoD investments in lunar space infrastructure

Posted by in categories: economics, military, space travel

WASHINGTON — The U.S. needs to flex its space muscles in the face of China’s lunar ambitions, argues a new report from the Mitchell Institute for Aerospace Studies released Jan. 17.

More specifically, the U.S. military should step up collaboration with NASA and support the development of infrastructure for scientific and economic activities in cislunar space, “as well as the means to secure those activities from potential threats such as territorial claims and irresponsible or hostile behavior,” writes Charles Galbreath, senior fellow for space studies at the Mitchell Institute.

Cislunar space — the region of space between Earth and the orbit of the moon — is becoming increasingly important strategically and economically due to potential lunar exploration, space mining and other commercial efforts poised to ramp up in the coming years.

North Korea Claims Successful Hydrogen Bomb Test

Posted by in categories: existential risks, military, nuclear weapons

Year 2017

North Korea claims it has again tested a hydrogen bomb underground and that it “successfully” loaded it onto the tip of an intercontinental ballistic missile, a claim that if true, crosses a “red line” drawn by South Korea’s president last month.

In a state media announcement, North Korea confirmed the afternoon tremors in its northeast were indeed caused by the test of a nuclear device, and that leader Kim Jong Un personally signed off on the test.

OpenAI’s policy update signals for the future of AI and military

Posted by in categories: government, military, policy, robotics/AI

From blanket bans to specific prohibitions

Previously, OpenAI had a strict ban on using its technology for any “activity that has high risk of physical harm, including” “weapons development” and “military and warfare.” This would prevent any government or military agency from using OpenAI’s services for defense or security purposes. However, the new policy has removed the general ban on “military and warfare” use. Instead, it has listed some specific examples of prohibited use cases, such as “develop or use weapons” or “harm yourself or others.”
