Layered protection for the seabed. UnderSec links optimised sensors, movement analysis and a neutron‑based ROV module to spot anomalies and identify threats on the seabed and ship hulls—towards real operational impact. 🔗Read more: undersec-project.eu/node/253 #CriticalInfrastructure

From algorithms to the sea. UnderSec has built a toolbox for underwater security: optimised sensor coverage, triangulation‑based localisation, maritime movement analysis and realistic underwater comms—all geared to protect critical subsea infrastructure. shorturl.at/RDgyE

Near‑optimal without the wait. By benchmarking against a brute‑force optimum, UnderSec’s constraint‑aware GA proves it can reconfigure sensor networks quickly while keeping coverage almost optimal. 🔗 More: undersec-project.eu/node/251 #GeneticAlgorithm #UnderSec #Optimization

Direction‑only sensors in a cluttered world. By treating known transmitters as obstacles, UnderSec’s optimisation keeps 3‑sensor triangulation coverage strong for perimeter and spectrum monitoring. 🔗Details: undersec-project.eu/node/250 #WSN #UnderSec

Choosing the right sensors, not just more sensors. UnderSec research uses a constraint‑aware genetic algorithm to pick which sensors to activate and how to orient them, maximising triangulated coverage around sensitive areas. 🔗 More: undersec-project.eu/node/249

From lab basin to the sea. UnderSec tests show CMIM can distinguish explosive and narcotic simulants in air, fresh and salt water using neutron‑induced gamma rays—next stop: ROV field trials. 🔗 More: undersec-project.eu/node/248 #UnderSec #NeutronTech #UnderwaterSecurity

From anomaly to answer. After sonar or cameras spot something suspicious, UnderSec’s CMIM uses neutrons to tell whether it’s debris, explosives or narcotics on the seabed or ship hull. 🔗 Details: undersec-project.eu/node/247 #MaritimeSecurity #UnderSec

See through sealed objects under water. UnderSec’s CMIM module uses pulsed fast neutrons on an ROV to identify explosives and narcotics by their elemental “fingerprint” near subsea infrastructure and hulls. 🔗 More: undersec-project.eu/node/246 #UnderSec #NeutronAnalysis

No single “best” underwater link. Acoustic = long range, optical = fast short links, EM = niche short‑range roles. UnderSec research highlights the need for hybrid networks to protect subsea infrastructure. 🔗 Full story: undersec-project.eu/node/244 #UnderwaterSecurity #UnderSec

Fast but fragile. Underwater optical links can deliver high data rates with low latency yet suffer from turbidity and alignment issues—ideal for short, high‑rate links near subsea assets in UnderSec. 🔗 More: undersec-project.eu/node/245 #UWOC #UnderSec #HorizonEU

Due to seawater conductivity, EM signals fade fast—long range needs very low frequencies and big antennas, but short-range links near subsea assets are still useful for UnderSec. 🔗 Details: undersec-project.eu/node/243 #UnderwaterComms #UnderSec

UnderSec partners review acoustic, EM and optical underwater communications, explaining why bandwidth is low, delays are high and noise is everywhere—vital context for subsea security systems. 🔗 More: undersec-project.eu/node/242 #UnderwaterSecurity #HorizonEurope #UnderSec

Visualising risk at sea. UnderSec’s tool shows cleaned vessel tracks on a map, colour-coded by speed, and highlights the latest position and heading near critical and underwater infrastructures. 🔗 Full story: undersec-project.eu/node/241 #MaritimeTraffic #UnderSec

Tested at sea. UnderSec’s automated movement analysis was tuned on simulated tracks, then validated with real manoeuvres alongside defence partners—supporting surveillance near underwater infrastructure. 🔗 More: undersec-project.eu/node/240 #FieldTrials #UnderSec #HorizonEU

Lightweight tools, strong insights. A new UnderSec decision-support system filters and predicts vessel motion using simple speed and distance rules—flagging anomalies near critical and underwater assets. Details: undersec-project.eu/node/239 #MaritimeSurveillance #UnderSec

From noisy AIS-like data to reliable tracks. UnderSec partners present an automated method that filters, interpolates and analyses vessel movements in real time around sensitive maritime and underwater areas. 🔗 More: undersec-project.eu/node/238 #UnderSec #MaritimeSecurity

Tested on Crete’s coastline. 🌊 Four sensors, multiple transmitters: UnderSec’s triangulation method accurately mapped transmitter positions in a real coastal environment. 🔗 Full story on undersec-project.eu/node/236 #UnderSec #FieldTest #Localization

Efficient localisation matters. UnderSec’s triangulation algorithm uses AOI filters and angle thresholds to localise multiple transmitters in real time—without overloading computing resources. 🔗 Read more on undersec-project.eu/node/235 #Algorithms #HorizonEurope #UnderSec

Triangulation, visualised. UnderSec partners turn angle measurements into small polygons that reveal where transmitters are likely to be—even with multiple signals and measurement errors. 🔗 Details on undersec-project.eu/node/234 #WirelessSensors #Localization #UnderSec

🗺️ Many transmitters, one map. UnderSec partners present a triangulation method using range-free sensors to estimate transmitter positions in real time over large areas. 🔗 More on undersec-project.eu/node/233 #HorizonEurope #UnderSec #Triangulation
