Unmanned Airborne Vehicle For Geophysical Surveying
First Claim
1. An unmanned airborne vehicle for geophysical surveillance of an area including a navigation system adapted to store a plurality of waypoints to be traversed, the vehicle comprising:
- a first magnetometer oriented to detect and measure magnetic anomalies in the area;
a second magnetometer for measuring magnetic response corresponding to pitch, yaw and roll of the vehicle;
a data acquisition system operatively coupled to the first and the second magnetometers for storing the magnetic anomaly measurements and magnetic response corresponding to the pitch, yaw and roll measurements and for removing the magnetic response measurements from the magnetic anomaly measurements; and
the data acquisition system maintaining therewithin a vehicle flight plan sequentially listing a series of coordinates and adapted to transmit at least one coordinate to the navigation system to update the plurality of waypoints.

Abstract
An un-manned airborne vehicle (UAV), for acquiring aeromagnetic data for geophysical surveying at low altitude on land or over water, comprising an extended fuselage that is adapted to hold and maintain magnetometer and a magnetic compensation magnetometer at a minimum distance from the avionics and propulsion systems of the UAV. The magnetometer measures magnetic anomalies and the magnetic compensation magnetometer measures magnetic responses corresponding to the pitch, yaw and roll of the UAV. A data acquisition system stores and removes the magnetic response measurements from the magnetic anomaly measurements. The data acquisition system also stores a survey flight plan and transmits the same to the avionics system. The generator of the UAV is shielded and the propulsion system is stabilized to reduce magnetic and vibrational noises that can interfere with the operation of the magnetometer.
