OrbitMFD is a multi-functional display that is included in the Orbiter basic package. The MFD displays the orbit of the vessel the user has control and the body the ship is orbiting as well as the orbit of a target vessel or natural body.

Orbital Elements displayed are:

|'''MFD Label'''||'''Element'''||'''Unit of Measure'''||'''Description'''
|-
|SMa||Semimajor Axis||m, km, AU||One-half the sum of the major diameter (Apoapsis and Periapsis). If Ecc ≥ 1, SMa will show a negative number
|-
|SMi||Semiminor Axis||m, km, AU||One-half of the minor axis
|-
|PeR<br>PeA||Periapsis Radius<br>Periapsis Distance||m, km, AU||Radial distance from the center of the reference body to the low point of the orbit<br>Radial distance from the surface of the body to the low point of the orbit
|-
|ApR<br>ApA||Apoapsis Radius<br>Apoapsis Distance||m, km, AU||Distance from the center of the reference body to the high point of the orbit<br>Radial distance from the surface of the body to the high point of the orbit
|-
|Rad<br>Alt||Radius Vector<br>Altitude||m, km, AU||Radial distance from the center of the reference body to the vessel<br>Radial distance from the surface of the reference body to the vessel
|-
|Ecc||Eccentricity||0 - ∞||Measure of how circular or non-circular the orbit is. Circle = 0, ellipse = >0 to <1, Parabola = 1, Hyperbola >1
|-
|T||Orbital Period (Time)||Seconds||How long it takes to make one revolution
|-
|PeT||Time to next Perapsis||Seconds||How long until the next periapsis, if past the periapsis
|-
|ApT||Time to next Apoapsis||Seconds||How long until the next apoapsis, if Ecc ≥  will show N/A
|-
|Vel||Velocity||m/s|| How fast the body is going 
|-
|Inc||Inclination||Degrees (°)|| Vertical tilt of orbit in reference to the ecliptic or the equator of the reference body
|-
|LAN||Longitude of Ascending Node||Degrees (°)||Horizontal orientation of the line of ascending node with respect to the vernal equinox
|-
|LPe||Longitude of Periapsis||Degrees (°)||Angle measured from the vernal equinox to the peiapsis as if the inclination is zero
|-
|AgP||Argument of Periapsis||Degrees (°)||Angle measured from the ascending node to the periapsis
|-
|TrA||True Anomaly||Degrees (°)||Position of the body along the orbit from the periapsis
|-
|TrL||True Longitude||Degrees (°)||Position of the body along the ecliptic from the vernal equinox
|-
|MnA||Mean Anomaly||Degrees (°)||Ficticious position of the body along the orbit from the perapsis as if it was moving at a constant velocity
|-
|MnL||Mean Longitude||Degrees (°)||Ficticious position of the body along the orbit from the perapsis as if it was moving at a constant velocity
|-
|G||Gravity contributiion||||Releative fraction of gravity of the reference body to the total gravitational field of the vessel
