Abstract:
1. A device for the emission of seismic vibrations, intended to be mounted on a mobile platform, which includes: a vibration assembly to send the vibrations into the ground, and a ground-hugging assembly for the device, the ground-hugging assembly fixed to the mobile platform and transfers the load from the mobile platform, in a ground hugging direction, onto the vibration assembly fluttered against the ground, with the vibration assembly being fixed to the ground-hugging assembly by compensation members designed to compensate for the perpendicularity anomalies between the general plane of the ground and the ground hugging direction, wherein the compensation members include long connecting elements having respective longitudinal axes and designed to be driven in traction along said respective longitudinal axes, the long connecting elements each having one end mounted to the vibration assembly and an opposite end mounted to a fixed part of the ground-hugging assembly, each end of each long connecting element being free to rotate around at least one axis of rotation substantially perpendicular to the ground hugging direction.
