Teledyne Gavia, manufacturer of the Gavia autonomous underwater vehicle (AUV), said it has integrated Marine Magnetics’ Explorer AUV magnetometer.
The Explorer AUV magnetometer is an omnidirectional sensor, which is towed behind the vehicle allowing it to operate outside the AUV’s magnetic signature.
According to Teledyne, dynamic and static testing of the Gavia AUV was conducted at Marine Magnetics’ facility in Canada and near Teledyne Gavia’s manufacturing facility in Kopavogur, Iceland to validate that the Explorer could measure variations in the magnetic field, rather than the influence of the Gavia moving through the water column.
Equipping the Gavia AUV with the Marine Magnetics Explorer enables it to combine high accuracy magnetic signature mapping along with Side Scan or Bathymetric survey data, Sub Bottom Profiler data, and still images, providing multiple detection levels of unexploded ordnance (UXO), pipelines, buried objects, or shipwrecks, the company explains.
“The Gavia AUV’s growing list of available sensors offers our clients an extremely flexible solution for a variety of commercial, military, and scientific applications. The integration of this small, yet sensitive, magnetometer allows users to have a low-logistics AUV with expanded capabilities for UXO mission capabilities in particular,” said Stefan Reynisson, general manager of Teledyne Gavia.
