GPOneAxisEllipsoid

How to call it

For using the GPOneAxisellipsoid class, the developer has only to create such an object as is:

ellips = new GPOneAxisEllipsoid("My Ellipsoid");

It is also ,possible to limit the available frames using two possibilities:

• Using a specific constructor:

ellips = new GPOneAxisEllipsoid("My Ellipsoid", GPRefFrame.ITRF, GPRefFrame.TIRF);

• … or using the setAvailableFrames() method:

ellips.setAvailableFrames(GPRefFrame.ITRF, GPRefFrame.TIRF);

We also may initialize the widget with predefined values:

final double REQ  = Constants.WGS84_EARTH_EQUATORIAL_RADIUS;
final double FLAT = Constants.WGS84_EARTH_FLATTENING;
final Frame ITRF = FramesFactory.getITRF();
final ExtendedOneAxisEllipsoid earth = new ExtendedOneAxisEllipsoid(REQ, FLAT, ITRF, "EARTH");

ellips = new GPOneAxisEllipsoid("My Ellipsoid", earth);

Display

In the first case, we will get:

As with the limitation of available frames:

How to use it

To get a [PATRIUS] ExtendedOneAxisEllipsoid object, we will just have to call for the getPatriusObject() method as below:

ExtendedOneAxisEllipsoid extEllips = ellips.getPatriusObject();

How it is stored

Here is the XML format:

  <OneAxisEllipsoid name="My_Ellipsoid">
    <Real name="sma" unit="km">6.3781363E3</Real>
    <Real name="flatness">3.3536E-3</Real>
    <Frame name="frame">
      <String name="name">ITRF</String>
    </Frame>
    <String name="name">My Ellipsoid</String>
  </OneAxisEllipsoid>
