Microflown AVISA Skysentry: acoustic counter-UAS system.<\/span><\/strong><\/h2>\n

The Microflown AVISA Skysentry is an acoustic counter-UAS (C-UAS) system from Microflown AVISA in Arnhem, built on the CASTLE sensor post, for detecting small, low-flying drones and other airborne platforms. Microflown AVISA states that initial tests have demonstrated detection range up to 250 m for a small (2 kg) quadcopter drone and up to 1 km for a small (2 kg) fixed wing drone, and that one sensor post is deployed by one person in less than 10 minutes.<\/p>\n

Key Facts:<\/strong><\/h3>\n
    \n
  • Sensor:<\/strong> Microflown AVISA states that the CASTLE sensor post hears all around in a full hemispherical bubble, capturing frequencies in the entire audio spectrum.<\/li>\n
  • Detection range:<\/strong> Microflown AVISA states that initial tests have demonstrated detection range up to 250 m for a small (2 kg) quadcopter drone, up to 1 km for a small (2 kg) fixed wing drone and up to 10 km for manned helicopters; detection ranges in general depend upon weather conditions, mostly wind speed and wind direction.<\/li>\n
  • Deployment:<\/strong> Microflown AVISA states that one sensor post is deployed by one person in less than 10 minutes.<\/li>\n
  • \u0388\u03be\u03bf\u03b4\u03bf\u03c2:<\/strong> bearing and elevation of the target, which can be used to cue another sensor or an effector.<\/li>\n
  • Operation:<\/strong> passive and unattended, all weather, day and night and non-line-of-sight, with low size, weight and power (SWaP).<\/li>\n
  • Targets:<\/strong> broadband targets such as multicopters and jet aircraft, and tonal targets such as propeller aircraft and manned helicopters.<\/li>\n
  • Configuration:<\/strong> available as a self-contained C-UAS system, or with interfaces for integration in a multi-sensor C-UAS system.<\/li>\n<\/ul>\n

    \u0395\u03c6\u03b1\u03c1\u03bc\u03bf\u03b3\u03ad\u03c2:<\/strong><\/h3>\n

    Microflown AVISA names three uses for the Skysentry: permanent protection of critical infrastructure with unattended sensors, short-term protection of events such as a VIP visit to a public square where rapid deployment matters, and military use, where CASTLE nodes can also run other firmware on manned or unmanned vehicles. Several networked CASTLE sensor posts can cover an area or fence a secured perimeter; Microflown AVISA states that the distance between the posts depends upon the detection range and the threat type.<\/p>\n

    About Microflown AVISA and MSS Defence:<\/strong><\/h3>\n

    Microflown AVISA, based in Arnhem, the Netherlands, develops and markets battlefield acoustic solutions. MSS Defence supplies the Microflown AVISA Skysentry Acoustic Drone Detector to defence and police organisations in Europe on quotation, with one point of contact from enquiry to delivery.<\/p>\n

    1. What is the Microflown AVISA Skysentry?<\/strong>
      The Microflown AVISA Skysentry is an acoustic counter-UAS (C-UAS) system from Microflown AVISA, built on the CASTLE sensor post. It detects airborne platforms by sound and gives their bearing and elevation.<\/li>\n
    2. How does the Microflown AVISA Skysentry detect drones?<\/strong>
      The CASTLE sensor post of the Microflown AVISA Skysentry hears all around in a full hemispherical bubble. Microflown AVISA states that the firmware splits the audio spectrum into frequency bins and estimates a direction of arrival for each, so that consistent bearings indicate a likely airborne threat.<\/li>\n
    3. What detection range does Microflown AVISA state for the Microflown AVISA Skysentry?<\/strong>
      Microflown AVISA states that initial tests with the Microflown AVISA Skysentry have demonstrated detection range up to 250 m for a small (2 kg) quadcopter drone, up to 1 km for a small (2 kg) fixed wing drone and up to 10 km for manned helicopters. Detection ranges in general depend upon weather conditions, mostly wind speed and wind direction.<\/li>\n
    4. How long does it take to deploy the Microflown AVISA Skysentry?<\/strong>
      Microflown AVISA states that one sensor post of the Microflown AVISA Skysentry is deployed by one person in less than 10 minutes.<\/li>\n
    5. Can the Microflown AVISA Skysentry work without line of sight?<\/strong>
      Yes. Microflown AVISA states that the Microflown AVISA Skysentry has an all weather, day and night and non-line-of-sight capability, and operates passively and unattended.<\/li>\n
    6. Can the Microflown AVISA Skysentry be integrated with other C-UAS sensors?<\/strong>
      Yes. Microflown AVISA states that the Microflown AVISA Skysentry is available as a self-contained C-UAS system, with interfaces for integration in a multi-sensor C-UAS system; its bearing and elevation output can cue another sensor or an effector.<\/li>\n<\/ol>\n<\/div>","protected":false},"excerpt":{"rendered":"
