Abstract
The present invention provides an airborne electromagnetic receiver having a large dimension to allow low transmitter base frequency. A modular and configurable suspension assembly is provided for use within a receiver support structure and suspending the support structure. The suspension assembly has a rigid support having a suspension portion, and links connecting the suspension portion and the suspended structure. The links are adjustable in length and tension to radially suspend said equipment support structure. The natural frequency of the suspension assembly and the suspended receiver motion can be optimized by adjusting mass distribution, suspension link length and suspension link tension. The suspension assembly can be used to suspend a receiver having large receiver coils. The suspension assembly converts high frequency vibration forces imparted on the receiver to a low frequency oscillation. The suspension assembly may also be tuned to avoid coincidence with the excitation frequencies.
