Description

The Centrifugal Effect Model block implements a mathematical representation of the centrifugal force acting on a body in the planet’s gravitational field. The gravity acceleration is calculated based on the angular velocity of the planet’s rotation around its axis.

Ports

Input

Xecef is the position of the point of force application
`matrix m by 3

The coordinates of the point of application of force in a planetocentric rotating coordinate system. If the Earth is a planet, the coordinates of the point are given in the Greenwich coordinate system.

Data types: Float64.

Output

gecef - acceleration of gravitational force
`matrix m by 3

The components of the acceleration of the gravitational force in a planetocentric rotating coordinate system. Measured in units of position per second squared.

Data types: Float64.

Parameters

Planet model - planet
Earth (by default) | Mercury | Venus | Moon | Mars | Jupiter | Saturn | Uranus | Neptune | Custom
