Orbit is an MFD mode which lists the elements and parameters for the orbit of the ship's orbit in reference to a central body, and a graphical representation of the orbit. The mode can also show the orbit of a target body orbiting the same body and its orbital characteristics. Orbit may be selected from the MFD selection page.
The display shows the Keplar, or two-body, orbit of the craft at the current date with respect to the reference body. Any natural body in Orbiter may be selected as the reference body. Because of perturbations to the orbit, it may change over time. Perturbing effects include other bodies in the Solar System, nonspherical gravity, atmospheric drag, and ship's engines, etc.
The orbital elements may be displayed in the ecliptic or equatorial frame of reference. The plane of the ecliptic is the orbital plane of the Earth and the equatorial plane is the plane of the equator of the reference body. ShiftF or the FRM button is used to switch back and forth between the reference frames, the 'Frm' value displays the current frame.
The graphical view can be switched between the planes of the ecliptic (ECL), equator (EQU), ship's orbit (SHP), or target's orbit (TGT) with ShiftP or with the PRJ button. The radius vector of the ship and target can be displayed from orbit focus (indicated by Rad, ApR, PeR), or by altitude above mean planet radius (Alt, ApA, PeA) with ShiftD, or the DST button.
ShiftTemplate:T or the TGT button opens a popup menu to select a target object, if you want no target, use ShiftN or the NT button. You can only display orbits for targets orbiting the selected reference object can be displayed.
Press ShiftH or the HUD button to switch the HUD to display the orbit reference object.
In the graphic mode: •The gray circle represents the mean radius of the reference object (Sun, planet, or moon). •The green circle, ellipse, parabola, or hyperbola represents the Kepler orbit of your ship. •The yellow circle, ellipse, parabola, or hyperbola represents the Kepler orbit of the target. •The small open circle on the ship's or target's orbit represents the apoapsis of the orbit. •The small closed circle on the ship's or target's orbit represents the periapsis of the orbit. •The line from the center of the body to the orbit is the radius vector, the end of the line where it touches the orbit is the ship's or body's current location. •
