Underwater tethered telemetry platform

A method of operating a telemetry system, comprising:

• providing a submersible telemetry platform, comprising:
• a body having a front end, a mid-section, and a tail end at an opposite end from the front end;
• at least one widely extending lift generating surface coupled to the body proximal the mid-section and configured in such a way as to provide lift to the body when a fluid flows across the at least one widely extending lift generating surface;
• at least one attitude control surface coupled to the body proximal the tail end and distal to the at least one widely extending lift generating surface, the at least one attitude control surface configured to control a pitch of the body in such a way as to modify the lift on the body between a negative lift and a positive lift;
• a control device coupled to the at least one attitude control surface and configured to control the at least one attitude control surface;
• and
• telemetry equipment coupled to the body and configured for wireless communication with at least one remote device;
• providing a base configured to be anchored at a subsurface location;
• providing a tether coupling the body with the base in such a way that the body has complete freedom-of-movement about a common center point at the base;
• and
• causing the telemetry platform to rise from an entirely submersed position within a body of liquid to a surfaced position at a surface of the body of liquid by adjusting a ramp angle of the at least one attitude control surface without requiring powered forward propulsion of the telemetry platform and without requiring a change in buoyancy of the telemetry platform.

A submersible telemetry system, comprising:

• a submersible telemetry platform, comprising:
• a body having a front end, a mid-section, and a tail end at an opposite end from the front end;
• at least two widely extending lift generating surfaces fixedly attached to the body proximal the mid-section and configured in such a way as to provide lift to the body when a fluid flows across the at least two widely extending lift generating surface;
• at least two attitude control surfaces coupled to the body proximal the tail end and distal to the at least two widely extending lift generating surfaces, the at least two attitude control surfaces configured to control a pitch of the body in such a way as to modify the lift on the body between a negative lift and a positive lift;
• at least two vertical rudder fins coupled proximal the tail end;
• a control device coupled to the at least one control surface and configured to control the at least one attitude control surface;
• and
• telemetry equipment coupled to the body and configured for wireless communication with at least one remote device;
• a base configured to be anchored at a subsurface location;
• and
• a tether coupling the body with the base in such a way that the body has complete freedom-of-movement about a common center point at the base;
• wherein the telemetry platform is controllable to rise from an entirely submersed position within a body of liquid to a surfaced position at a surface of the body of liquid by adjustment of a ramp angle of the at least one attitude control surface with a total power consumption required to effect the rise being limited to that which is necessary to activate the at least one attitude control surface and without requiring a change in buoyancy of the telemetry platform.
