SyntaxThe InitialOrbitSolver type exposes the following members.
Constructors| Name | Description | |
|---|---|---|
 | InitialOrbitSolver |
Initializes a solver. The GravitationalParameter is set to GravitationalParameter.
|
| InitialOrbitSolver(Double) |
Initializes a solver.
|
Properties| Name | Description | |
|---|---|---|
 | GravitationalParameter |
Gets or sets the gravitational parameter used to determine the orbit.
|
Methods| Name | Description | |
|---|---|---|
| Clone | Creates a new object that is a copy of the current instance. |
| Equals | Determines whether the specified object is equal to the current object. (Inherited from Object.) |
 | Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
| GetHashCode | Serves as the default hash function. (Inherited from Object.) |
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
| Solve(Cartesian, Cartesian, Cartesian) |
Solves the initial orbit determination problem using the Gibbs method.
|
| Solve(Cartesian, Cartesian, Cartesian, JulianDate, JulianDate, JulianDate) |
Solves the initial orbit determination problem using the Herrick-Gibbs method for closely spaced positions.
|
| SolveForAllVelocities(Cartesian, Cartesian, Cartesian) |
Solves the initial orbit determination problem using the Gibbs method.
|
| SolveForAllVelocities(Cartesian, Cartesian, Cartesian, JulianDate, JulianDate, JulianDate) |
Solves the initial orbit determination problem using the Herrick-Gibbs method for closely spaced positions.
|
| ToString | Returns a string that represents the current object. (Inherited from Object.) |
Remarks
Note that there are requirements for the input positions and times. In both methods the positions should be approximately co-planar (within a degree or two).
The input positions should have large angular separation when using the positions only (Gibbs) solver, and small angular separation when using the positions and times (Herrick-Gibbs) solver.
As outlined in "Fundamentals of Astrodynamics and Applications", below 1° in angular separation the Herrick-Gibbs method is recommended, and above 5° the Gibbs method is recommended.
