Abstract
Various examples are provided for systems and methods for geodesy in shallow water. In one example, a method includes obtaining, from a sensor module, a position of a superstructure of a moored device. At least one measurement corresponding to a heading, a pitch, or a roll of the superstructure can be obtained from the sensor module. An estimated position of an anchor, ballast, or other seafloor marker of the moored device can be determined based on the position of the superstructure and at least one corrected heading associated with the at least one measurement. The at least one corrected heading can be determined by applying a magnetic declination correction to the at least one measurement.
Claims19
A method for geodesy in shallow water, comprising:
- obtaining, from a sensor module, a position of a superstructure of a moored device;
- obtaining, from the sensor module, at least one measurement corresponding to a heading, a pitch, or a roll of the superstructure;
- and
- determining an estimated position of a seafloor marker of the moored device based at least in part on the position of the superstructure, and at least one corrected heading associated with the at least one measurement;
- wherein the seafloor marker is below the shallow water at a depth less than 200 meters.
A method for geodesy in shallow water, comprising:
- a processor;
- and
- program instructions stored in memory and executable by the processor that, when executed, cause the processor to:
- obtain a heading, a pitch, and a roll of a superstructure of a moored device;
- and
- determine a horizontal component of a displacement of a seafloor marker of the moored device based at least in part on extracting a three-dimensional position associated with the heading, the pitch and the roll of the superstructure;
- wherein the seafloor marker is below the shallow water at a depth less than 200 meters.
A system for geodesy in shallow water, comprising:
- a moored device comprising a superstructure connected to a seafloor marker;
- a computing device communicatively coupled to a sensor module connected to the superstructure;
- and
- at least one application executable in the computing device, wherein, when executed, the at least one application causes the computing device to at least:
- determine a position of the superstructure;
- determine a heading, a pitch, and a roll of the superstructure;
- and
- determine an estimated position of the seafloor marker based at least in part on the position, the pitch, the roll, and a corrected heading associated with the superstructure;
- wherein the seafloor marker is below the shallow water at a depth less than 200 meters.
