ABSTRACT:
A free falling or projectable penetrometer for simultaneously determining a multiplicity of ground characteristics during penetration and retracking cycles and while at rest following full penetration. The apparatus employs a multitude of sensing elements and is further characterized by the presence of at least three electrode pairs one aligned with the central axis of the penetrometer with the other two pairs being positioned orthogonally in a common plane that is itself perpendicular to the central axis. An onboard power supply is included together with telemetry equipment to generate ground characteristics and transmit such signals.
