Classes
  ClassDescription
Public classCode exampleAxes
A set of axes which may vary with time relative to another set of axes.
Public classAxesAlignedConstrained
A set of axes with the one axis aligned with the Principal direction vector and another axis constrained to minimize the angular separation from the Reference vector. These axes remain aligned and constrained as the Principal and Reference vectors change with time. By default, the principal axis is the x-axis and the reference axis is along the z-axis.
Public classAxesAlongTerrain
An Axes defined by the surface normal to the terrain surface. This is useful when modeling the orientation of a ground vehicle moving over terrain. The x-axis is in the direction of motion. The y-axis is parallel to the terrain surface. The z-axis is orthogonal to the terrain surface pointing down.
Public classAxesBPlane
The axes that a VectorBPlane are computed in. See the documentation for the VectorBPlane for more information of B-Planes.
Public classAxesEastNorthUp
The set of axes defined by the local East, North, and Up directions at a point with respect to the shape of a central body as the point moves over time.
Public classAxesEvaluator

Evaluates an Axes over time.

The result of evaluating will be a Motion<UnitQuaternion, Cartesian> representation of the orientation and rotation of these axes at the specified JulianDate. The AxesEvaluator will attempt to provide rotational rate information up to the requested order.

The rotation reported by this evaluator represents the rotational transformation from the original axes to these axes. By calling Rotate(UnitQuaternion) with the reported UnitQuaternion, it will transform the given cartesian vector from the original axes to be expressed in these axes.

The rotational rates reported by an AxesEvaluator are the rotational rates of these axes with respect to and expressed in the base axes in which these axes are defined. e.g. The "FirstDerivative" (if available) of a platform body axes defined in the fixed frame will represent the angular velocity of the body in the fixed frame.

Public classAxesFixedAtJulianDate
A set of Axes which is defined by the instantaneous orientation of another set of axes at a specified JulianDate.

Public classAxesFromBankAngle

An Axes defining a first order representation for an aircraft in steady flight with the bank angles specified by changes in the horizontal acceleration vector. The bank angle is determined by assuming steady flight and calculating the angle necessary to provide the corresponding horizontal acceleration. The axes will examine the acceleration around the special times of interest and determine how much time is needed before and after that point in order to transition between the two bank angles based on the given roll rate. When no horizontal acceleration is present, this is the same as an axes aligned with the x axis along the velocity and the z axis constrained toward nadir.

Note that while this will attempt to use the TargetRollRate, if there is a sequence of banking maneuvers in quick succession the TargetRollRate will not be feasible. In this case, the roll rate will exceed the target as necessary.

Public classScalarRouteHeight

A scalar representation of the height dynamics of the route with respect to the given terrain reference surface.

This represents the "flat" height without taking into account the effects of the curvature of the non-euclidean Ellipsoid surface of the central body. The effect of the curvature tends to be small for values near the surface, creating discrepancies of less than a millimeter per second in the velocity. If the route is defined with respect to ragged terrain, the effect of that terrain with respect to the underlying surface is much more significant than the curvature of the underlying surface. While the value of the height will generally be exact, the derivative of this scalar will differ slightly from the value of the instantaneous fixed-frame velocity along the surface normal.

Public classScalarRouteSurfaceSpeed

A scalar representing the speed along the ellipsoid surface upon which the route is defined.

For aircraft, this is essentially equivalent to the "ground speed". However, if the 'ground' has a non-zero height with respect to the Ellipsoid surface (i.e. if there is terrain data included in the analysis), the speed produced by this Scalar represents the speed along the Ellipsoid and not the speed along the terrain.

For ground vehicles (and ships), this represents the speed tangent to the Ellipsoid and does not take into account the terrain normal when computing the speed.

Note that it may be counter intuitive that the Value reported by this scalar represents the "speed" while the FirstDerivative represents the acceleration (derivative of speed).

Public classScalarRouteTotalSpeed

A scalar representing the total speed with respect to the ellipsoid surface upon which the route is defined. This includes both the horizontal and vertical components of velocity.

This represents the "flat" total speed without taking into account the effects of the curvature of the non-euclidean Ellipsoid surface of the central body. The effect of the curvature tends to be small for values near the surface, creating discrepancies of less than a millimeter per second in the velocity. If the route is defined with respect to ragged terrain, the effect of that terrain with respect to the underlying surface is much more significant than the curvature of the underlying surface. The derivative of this scalar will differ slightly from the value of the instantaneous fixed-frame velocity.

Note that it may be counter intuitive that the Value reported by this scalar represents the "speed" while the FirstDerivative represents the acceleration (derivative of speed).
