Module: pointMassGravityModel¶

class PointMassGravityModel : public GravityModel ¶

#include <pointMassGravityModel.h>

The point mass gravity model

Public Functions

inline virtual std::optional<std::string> initializeParameters() override¶: Does nothing, as the point-mass gravity model has no parameters other than muBody, which must be set separately

virtual std::optional<std::string> initializeParameters(const GravBodyData&) override¶: Reads the only necessary parameter (muBody) from the given GravBodyData

virtual Eigen::Vector3d computeField(const Eigen::Vector3d &position_planetFixed) const override¶

Returns the gravity acceleration at a position around this body.

The position is given in the body-fixed reference frame. Likewise, the resulting acceleration should be given in the body-fixed reference frame.

virtual double computePotentialEnergy(const Eigen::Vector3d &positionWrtPlanet_N) const override¶

Returns the gravitational potential energy at a position around this body.

The position is given relative to the body and in the inertial reference frame.
