An access constraint that projects the displacement vector from one object to another into a given axis-aligned plane and requires that the angle of the projected vector, measured from the first axis defining the plane toward the second, is within a range of values.
An access constraint that requires that the angle of the displacement vector between two objects above a given axis-aligned plane is within a range of values.
This constraint limits access to within a certain cartographic region.
An access constraint in the shape of an elliptic cylinder (or a circular cylinder by setting the x semiaxis length equal to the y semiaxis length) defined by a central point, a heading for the x semiaxis, and the corresponding x semiaxis and y semiaxis lengths.
An access constraint that takes a set of points and altitude layers to create a layered volume access constraint.
A representation of an individual projected volume used in
An Access constraint that requires that the view from one object to another not be obstructed by a central body such as the Earth or another planet.
An Access constraint that requires that an object be between a span of elevation angles from any or all of the points along a given line on the surface of the central body.
An access constraint which is based on a communication link parameter defined by a
An access constraint which is based on a communication or link budget parameter defined by a
An access constraint which requires the Ground Sample Distance (GSD) to be greater than a minimum and less than a maximum value.
A class representing a generalized constraint based on a given evaluator with a minimum and maximum threshold value which indicate the satisfaction region.
An access constraint which is based on a radar system performance parameter defined by a
An Access constraint that requires that the surface distance between two objects be above a minimum and below a maximum in meters.
Indicates the model to be used.
