java.lang.Object

org.orekit.propagation.FieldAbstractPropagator<T>

org.orekit.propagation.analytical.FieldAbstractAnalyticalPropagator<T>

org.orekit.propagation.analytical.tle.FieldTLEPropagator<T>

org.orekit.propagation.analytical.tle.FieldSGP4<T>

Type Parameters:

T - type of the field elements

All Implemented Interfaces:

FieldPropagator<T>, FieldPVCoordinatesProvider<T>, ParameterDriversProvider

public class FieldSGP4<T extends org.hipparchus.CalculusFieldElement<T>>
extends FieldTLEPropagator<T>

此类包含使用SGP4模型计算传播坐标的方法。

用户不应该在此类中进行操作，因为它由TLEPropagator在内部处理。

此实现在很大程度上受到论文和源代码重新审视Spacetrack报告＃3的启发，并完全符合其结果和测试用例。

Since:

11.0
