Infrared remote sensing technology Infrared remote sensing is to use infrared sensitive devices to complete the required measurement tasks at a distant (high altitude) place without contacting the measured target. For example, infrared remote sensing devices are used on reconnaissance satellites to photograph or detect military targets. Recently, infrared remote sensing technology has been used in the development of agricultural resources. https://lnkd.in/gtCFZJg2

This is a great example of defense innovation, one of hundreds of awards on AMTC that move our nation forward. On several occasions I have heard some confusion about what a DoD program can do on an Other Transaction Agreement (OTA). Those that follow me know I have spoken quite a bit about the progress in Army Aviation (FVL / FLRAA / UAS), and also the component level programs that have leveraged modules as well as whole systems on OTA awards. What I have written less about are these additional awards in the areas of missiles, space, general purpose technology, and more that I regularly see on AMTC award cycles. Thanks govmates for posting this article! We need to talk more about successes and solutions. I have been privileged to serve on the AMTC Executive Committee for the past several years and still regularly hear program teams confused about the limits, colors of money, types of programs, speed, or other aspects of using an OTA. One of the best aspects is our model for open collaboration - we can help you reach the dialogue and refinement potential where you are in the current program. Whether you are on the industry side (such as helping refine a solution from a need) or on the government side (fostering competition while still refining a requirement) then you have options you may not be aware of. One of the ExCom team would be happy for offer our AMTC Education and Outreach briefing to you so you can consider a project, large or small, on the AMTC contract.

Which Antennas are used in Submarines? Under-sea communication is a tough challenge! The main reason behind this is the high conductivity of salt water. Radio waves tend to travel freely in nonconductors (air or vacuum) while it face difficulty in traveling through good conductors (because of the skin effect). So, previously acoustic devices were used for submarine communication. Later, it was found that we can use radio waves for under-sea communication but their frequency should be very low (as skin depth is inversely proportional to frequency), thus presently very low-frequency radio wave is used. That was the basic of under-sea radio communication. At such a large wavelength (low freq.) the efficiency of the antenna gets reduced because of the reduction of its electrical length. To improve its efficiency, lots of copper is buried in the grounding system of the antenna. So, the answer is a simple dipole or monopole antenna would do the work. #antenna #defence #aerospace #technology

With the proliferation of small satellites in low Earth orbit, the emphasis on payload development to support evolving mission needs remains a key focal point for industry. OTA consortia have been an excellent vehicle to foster collaboration amongst industry and enable non-traditional defense contractors to deliver innovative solutions to the government. The Aviation & Missile Technology Consortium (AMTC) supports space-related R&D needs, encompassing a variety of guidance, manufacturing and aviation technologies. One such case study was an award made by Army via AMTC to Iridium for $30 million to “develop a payload to be hosted on small satellites that supports navigation systems, guidance and control for the global positioning system (GPS) and GPS-denied precision systems.” Iridium partnered with Satelles (whom they later acquired) and SEAKR Engineering, LLC (later acquired by Raytheon) to develop this payload with the goal of more effective sensor-to-soldier data transmission in the field, facilitated by a more rapidly-deployable smallsat constellation.

Due to the vulnerabilities of GPS signals, such as jamming and spoofing by adversaries, experts stress there is no single alternative. The U.S. military is exploring various alternatives to #GPS to enhance reliability and counter vulnerabilities. These alternatives include: 🔸 Inertial Navigation Systems (INS): Utilizing gyroscopes and accelerometers to track movement without external signals. 🔸 Magnetic Navigation: Leveraging the Earth's magnetic field for orientation and positioning. 🔸 Celestial Navigation: Using stars and other celestial bodies for navigation. 🔸 Signals of Opportunity: Employing signals from existing radio frequency sources such as television towers and cell towers. A combination of these methods is necessary to ensure robust and resilient positioning, #navigation, and timing (PNT) capabilities.

In the 1920s, it was discovered that when lead sulfide was exposed to infrared thermal radiation, its electrical impedance decreased. This phenomenon is called photoconductivity or photoconductivity, and photoconductivity also occurs under other wavelengths of light. So a preliminary design scheme was developed, which measures the current intensity of infrared radiation by measuring the changes in the impedance value of lead sulfide, and controls the missile flight based on the strength. Furthermore, design a guidance head to guide the missile towards a target emitting infrared thermal radiation, either an aircraft or a missile. Throughout World War II, major warring countries attempted to use the principles of photoconductivity and image enhancement technology to produce displays specifically for nighttime use, almost exclusively for remote flying object detection. However, these attempts were not very successful, and only a night vision system called the "wrench" developed by Nazi Germany was eventually put into production. This system used a long tube placed in front of the aircraft windshield, and pilots could see the situation directly ahead through it at night. In addition, infrared imaging displays were widely used in various ground combat systems, including tanks, armored vehicles, and even sniper rifles. With the accumulation of experience in this area, German scientists also experimented with an automated missile guidance system to guide their Enzian missiles to hit targets in homeland air defense operations by tracking the heat emitted by enemy aircraft engines. The Enzian missile uses a simple detector as the core part of the guidance head, which is placed at the focal position of a telescope, and has four control surfaces on the missile body composed of the guidance head and telescope. The Enzian missile detects changes in the focus of a telescope through a detector, and then controls the missile to fly towards the target. However, the war ended before the development of this missile was completed. #IR #OPTICS

Exciting developments on the horizon for Australia's defence capabilities! The recently launched iLAuNCH Trailblazer project, a collaboration of Northrop Grumman Australia and Spiral Blue aimed at developing a cutting-edge missile detection capability. This initiative aligns well with one of the SDIPs outlined in the 2024 DIDS and addresses the AUKUS Pillar II immediate priorities such as hypersonics and counter-hypersonics, enhancing our nation's defence capabilities. Executive Director Darin Lovett noted, "We are bringing together Australian know-how to build an advanced space surveillance system for missile defence on small satellites." The project will leverage advanced infrared detection technology and AI/ML techniques for effective threat identification.

As long as they move in their orbit very high above the surface of the Earth, and as long as there are not yet flying spacecraft that can fight at that level of their orbit, and as long as there are no jamming techniques capable of sufficient electromagnetic power to access to their cosmic coordinates, they are completely protected.
