Based on this patent application, ECA Group widens its magnetic solutions portfolio with an aerial portable magnetic ranging system called Sterna® and consisting in a magnetometer and its digitizer embedded in UAV IT180 airborne drone (developed by ECA Group). To perform the mapping in a horizontal plane of the vessel, Sterna® overflies the vessel. Data are transmitted onboard, detection risk is automatically estimated and degaussing parameters are computed.

 

Features

  • Determines magnetic risks on the operational theater
  • Only one hour of total operation: deployment and measurement
  • Operated from the vessel: neither onshore station nor cable links
  • Usable in shallow water as well as open sea
  • Fully containerized, light and stand-alone solution
  • Cost effective solution

Applications for Defence & Security

  • Magnetic signature reduction

Mine and mad risk calculation

  • Surface vessels and submarines magnetic signature measurement
  • Automatic detection risk estimation
  • Automatic degaussing system adjustment

Large operation conditions

  • Only one operator is needed for a complete measurement
  • Can be operated from the shore (up to 3 km) as well as from vessel when flight deck available
  • Can be used on operational theatre
  • Data can be transmitted on board in real time while Sterna overfly the vessel or they can be stored on a storage device
  • Wind resistance up to 60 KM/H
  • Automatic take-off and landing

IT180-120

  • Gasoline version with an endurance up to 120 minutes
  • Deployed in less than 15 minutes
  • High stability and robustness drone
  • Extremely harsh weather operations (-10°C to 40°C, wind up to 60km/h, snow, rain, heat)
  • Maximum payload of 5 kg for a drone weight of 16 kg
  • Maximum speed of 70 km/h
  • Maximum ceiling of 3 km
  • Remotely controlled through a radio link

Patented solution

Sterna is a unique solution composed of a magnetometer and its digitizer embedded in UAV IT180 airborne (develop by ECA-GROUP). The magnetic measurement is performed through a high performance algorithm to compensate the sensor’s errors and the drone magnetic influence.

Magnetic measurement

  • Fluxgate three axes magnetometer
  • High performance low noise sensor
  • Wide operating temperature range (-40°C to 70°C)
  • High performance digitizer
  • Magnetometer and digitizer embedded in drone foot
