IMFD Delta Velocity Program

The Delta Velocity Program is a manual Delta Velocity tool. You can input how much delta velocity and in which direction and hit Autoburn and the program will change your velocity as such. You should probably not need to use this program all that much, but it is a nice tool to have.

Text Items:

The following are all of the text items not explained in the diagram above:

TEj — Time until burn

Time in seconds until the burn initiates (if you have enabled Autoburn).

GET — GET Time of Burn

Time of the Burn in GET

Vel. Frame — Reference Mode Option

Reference Mode Option. This should be left in Vel. Frame. Other options are Local Vrt., P30 LVLH, and Global.

Off Axis — Burn Mode

Burn Mode. Off Axis is the only option.

dVf — Delta Velocity in the x direction.

Delta Velocity to apply in the x direction. It‘s easier to think of the f standing for ―forward‖ (prograde is positive, retrograde is negative).

dVp — Delta Velocity in the y direction.

Delta Velocity to apply in the y direction. It‘s easier to think of the p standing for ―planar‖ (north is positive, south is negative).

dVo — Delta Velocity in the z direction.

Delta Velocity to apply in the z direction. It‘s easier to think of the o standing for ―outward‖ (positive is away from a planet, negative is towards a planet).

Tot — Total Delta Velocity

Total Delta Velocity to apply.

ApA — Apoapsis Altitude

Altitude of the Apoapsis of your target orbit.

PeA — Periapsis Altitude

Altitude of the Periapsis of your target orbit.

Ecc — Eccentricity

Eccentricity of your target orbit.

RIn — Relative Inclination

Relative inclination of your target orbit.

LAN — Longitude of Ascending Node

Longitude of Ascending Node of your target orbit.
