From Wonder to Wisdom: Cracking the Code of Missile Guidance As I gazed up at the sky, I wondered: "How do missiles pinpoint their targets with such precision?" That childhood curiosity ignited a quest for knowledge, driving me to uncover the secrets behind missile guidance. The Tech Behind the Target I discovered that missile guidance relies on a symphony of advanced technologies: - Radar detection: Identifying aircraft and plotting their course through radio waves, using Doppler shift to calculate speed and distance. - Infrared tracking: Locking onto heat signatures emitted by engines, allowing missiles to engage targets in adverse weather conditions. - GPS-terrain fusion: Combining GPS data with 3D terrain maps to adjust trajectory mid-flight, ensuring pinpoint accuracy. - Real-time data links: Ensuring precision through continuous updates from command centers, accounting for target maneuvers and environmental factors. How it Works Together These technologies converge to create a robust guidance system: - Initial target detection via radar - Infrared seekers take over for terminal guidance - GPS-terrain fusion adjusts trajectory - Real-time updates refine targeting #MissileGuidance #Innovation #Curiosity #STEM #Technology

#EcosystemMapping GNSS alternative technologies - who are the key players? With global navigation satellite systems (GNSS) vulnerable to disruption, there is a clear need for alternative position, navigation, and timing (PNT) technologies. Outsmart Insight has mapped the global landscape of next-generation approaches, ranging from quantum inertial measurements to visual-based navigation, for a major defence manufacturer.

This paper considers a relay-assisted airborne #free #space #optical (#FSO) system in which serial and parallel relaying are deployed together. The authors deploy relay selection in each hop and select the relay that provides the maximum instantaneous signal-to-noise ratio (SNR). To achieve this in practice, it is necessary to estimate the channel coefficient per hop and feed it back to the preceding transmitting/relaying node. Due to the semi-fixed hovering position of rotary-wing #unmanned #aerial #vehicles (#UAVs), this estimate will likely be outdated for the airborne channel. ----MOHAMMED ELAMASSIE, Dr. Sadiq M.

MH370 Geoscience Malaysian radar data revealed and analysed?: Manually piloted flight and simulated emergency descent We completed the detailed analysis of the unpublished radar data coming from the Malaysian Military tracker. This original data recently discovered by us is the only one known so far in numerical format with geodetic coordinates of the points on the track from Kuala Lumpur until 18h22 UTC. The important conclusions confirm our analysis on the reconstructed trajectory (reported at www.mh370-caption.net): 1- the aircraft was manually piloted from IGARI until Pulau Perak Island (at least) 2- an approximate vertical profile could be determined thanks to the cross-analysis of radar coverages leading to a better knowledge of this segment of the flight. In particular, an emergency descent would have been simulated confirming a voluntarily depressurisation of the airplane as hypothesised in our previous report. All this consolidated our own conclusions formulated in our previous report. The report, data and an accompanying video are available at https://lnkd.in/epzt9Cin

The average passenger jet can have anywhere from 30 to 50 antennas, adding weight and drag to the aircraft. Reducing weight while ensuring unquestionable reliability are critical factors for aerospace communication. Our ceramic components can be found in many on-board communication systems. In addition to antennas, or ceramics are also used in altimeters, GPS (shown below), and Traffic Avoidance Collision Systems (TCAS).

The HRG Crystal is a Hemispherical Resonator Gyroscope used to measure the rotation of a platform, whether aircraft, ship, tank, or other vehicle, to calculate its exact position and attitude. Safran is proving that the HRG Crystal innovative approach is a real game changer in high-end navigation. Over the past few years, Safran has introduced its new generation of HRG-based Inertial Navigation System (INS) designed to equip all types of platforms. Due to its straightforward design and mature technologies, the HRG Crystal enables Safran to create advanced inertial navigation systems with exceptionally high reliability for both civil and military applications. These systems provide a broad range of performance specifications, offering versatility in choice. What distinguishes the HRG Crystal is its unique capability to deliver consistent performance levels from standard to very high, all within a compact size. Furthermore, through the innovative design, Safran’s HRG Crystal can be produced cost-effectively, making its intrinsic performance accessible to the mass market.

JWST has (presumably) detected an artificial light source from Proxima B, in a habitable zone. IT IS TIME to start thinking about the aerospace industry beyond 1960's technology. The fastest rocket would take many thousands of years to get there. Are you ready to be part of the next aerospace evolution?

The interaction between shock and vortex on a delta wing leads to severe buffeting at high angles of attack.

Hello everyone. I just registered for the CORS 2024 #conference in London, ON. Hopefully I will see some folks I haven't seen in a while. If you're curious about where my research has led me, then maybe swing by my presentation entitled: A location-routing problem involving military aeromedical evacuation assets and field hospitals in antiaircraft threat environments The abstract is as follows: We propose a 2-stage stochastic, location-routing problem which sites evacuation helicopters and field hospitals within military theatres of operations; this model probes the interactions between facility siting and vehicle routing in antiaircraft threat environments. Siting occurs in the first stage while facility assignment and vehicle routing are conducted in the second. The siting portion of the model is a fixed-charge formulation with two classes of facility. The routing portion of the model minimizes a combined objective of distance and antiaircraft threat exposure; routing constraints prevent overflight of the same location twice in any mission, limit course alteration magnitudes and enforce compliance with aircraft wind operating limits. Solution methods include CLPEX and two novel hybrid metaheuristics. The metaheuristics combine Simulated Annealing (SA) or Tabu Search (TS) with a variant of A* we developed for another study; SA and TS make siting and assignment decisions while our A* variant handles helicopter routing. Numerical experiments and case studies are provided. #PhD #OperationsResearch #metaheuristics
