We decided to carry out a magnetometer survey of the Tunguska Event epicenter. Magnetic anomalies in epicenter and deviations from anomalies driven by geology could reveal the mechanism or cause of the explosion in Tunguska.
Since the conventional hand-held method of magnetometer survey is due to rough terrain and large swamps nearly impossible at this area, our survey is UAV (drone) based magnetometer survey. Thanks to the UAV we were able to measure many points in a relatively short time period and regardless of the terrain difficulty.
We programmed drone to fly profiles autonomously in the north to south loop pattern. This way we measured area 8.5 km x 4 km with 100 m line spacing.
We were flying fixed altitude at 110 m above our home point.
