Constructor Details

OceanTides

@DefaultDataContext
public OceanTides(Frame centralBodyFrame,
 double ae,
 double mu,
 int degree,
 int order,
 IERSConventions conventions,
 UT1Scale ut1)

Simple constructor.

This constructor uses pole tides, the default step and default number of points for the tides field interpolation.

This constructor uses the default data context.

Parameters:

centralBodyFrame - rotating body frame

ae - central body reference radius

mu - central body attraction coefficient

degree - degree of the tide model to load

order - order of the tide model to load

conventions - IERS conventions used for loading ocean pole tide

ut1 - UT1 time scale

OceanTides

@DefaultDataContext
public OceanTides(Frame centralBodyFrame,
 double ae,
 double mu,
 boolean poleTide,
 double step,
 int nbPoints,
 int degree,
 int order,
 IERSConventions conventions,
 UT1Scale ut1)

Simple constructor.

This constructor uses the default data context.

Parameters:

centralBodyFrame - rotating body frame

ae - central body reference radius

mu - central body attraction coefficient

poleTide - if true, pole tide is computed

step - time step between sample points for interpolation

nbPoints - number of points to use for interpolation, if less than 2 then no interpolation is performed (thus greatly increasing computation cost)

degree - degree of the tide model to load

order - order of the tide model to load

conventions - IERS conventions used for loading ocean pole tide

ut1 - UT1 time scale

See Also:

• GravityFields.getOceanTidesWaves(int, int)
• OceanTides(Frame, double, double, boolean, double, int, int, int, IERSConventions, UT1Scale, GravityFields)
