Orbit geometries

The contour programmed in the orbit channel must meet a number of requirements depending on the orbit strategy selected. Here, there are two strategies provided to determine the way in which the contour programmed in the orbit channel is reduced as a function of the radius.

Scaling: 0 <= R <= R_MaxScal

The orbit channel scales the orbit geometry using the linear scaling factor = R/ R_MaxScal in relation to the centre (0/0) as a function of the current radius.

Equidistant: R_MaxScal < R <= R_MaxEquid

A suitable equidistant to the program contour is calculated for the orbit geometry.

The following applies to the scaling and equidistant ranges: 0 <= R_MaxScal <= R_MaxEquid.

Scaling can be deactivated by R_MaxScal = 0. The equidistant range can be deactivated by R_MaxEquid <= R_MaxScal.

The right-hand part of the figure below shows how the rectangle (grey) programmed in the orbit channel is scaled down to R_MaxScal with an equidistant distance. The scaling is then changed from R_MaxScal to R=0. The requirements of orbit geometry are explained below.
