San Diego Bay
Explorer was integrated with the IVER2 AUV. The integration was tested by a third party at a blind UXO trial for the Geneva International Centre for Humanitarian Demining.
Two 250m x 120m surveys were conducted over the same area. One before seeding with simulated UXO targets, and the second after seeding, on the following day. The targets ranged in size from 60 mm to 160 mm. The smallest target was 1 kg.
The total-field map (figure 1) shows significant geological background obscuring small near-surface targets and a small pipeline in the lower half of the block. The unseeded and seeded area’s gradient map clearly show 10 UXO targets. It was confirmed that all ten UXO were reliably detected after seeding.
Gradient Data From A Single Explorer Sensor
Overhauser sensors have high sensitivity, no dead zones or heading error, all of which make it orders of magnitude more accurate than any other magnetometer. These characteristics coupled with Iver’s great control of position, depth and altitude yielded exceptional quality data.
