Undersea position and velocity measuring system and process
First Claim
1. A navigation system comprising:
- a submersible vessel having thereon a navigation processor;
a buoy having thereon a GPS device;
a cable that couples the navigation processor with the buoy;
wherein the cable contains (a) a data link between the vessel and the GPS device for communicating GPS data to the processor and (b) a location device for aiding in the determination of the location of the cable to the submersible vessel; and
wherein the processor computes a GPS position relative to the submersible vessel based on the received GPS data and the location device data.

Abstract
This invention relates to a GPS navigation system comprised of a submerged vessel having a navigation processor associated via buoyant cable with a buoy having a GPS device; wherein the cable contains: a data link between the vessel and the GPS device; and a location device for the determination of the location of the cable to the vessel; and wherein the processor computes a GPS position relative to the vessel. The invention also relates to a navigation process comprising the steps of: attaching a cable between a buoy and a submerged vessel; providing a GPS data relative to the buoy and cable location data over the cable to the submerged vessel; and using the GPS position of the buoy and location data to compute the GPS position of the submerged vessel.
