Interplanetary MFD (IMFD) is an Orbiter add-on created by Jarmo Nikkanen. It facilitates travel throughout the solar system by calculating and displaying a vessel's predicted trajectory.
The current version is IMFD 5.1g released on March 28, 2008.
- Map program can be used to display entire solar system and predict the actual course of the vessel with numerical trajectory calculator. The predictor can be also used to predict a hypothetical scenarios as well. This is very useful when planning a free-return trajectories.
- Course program is a collection of minor navigation programs those will let you to navigate through the solar system to other planets, moons and comets. Primary programs are based on the Lambert solver. In the most simplest case only a date of ejection and the Date of arrival is required as an user input.
- BaseApproach program is designed for Apollo style Moon to Earth return missions. It can be used to target a bases on the Mars and land directly without an orbit insertion. The program will also allow to establish an orbit right over a specific base on a planet so that it is possible to continue the descent on the base. That's very useful when landing on the Moon.
- Surface Launch program is usefull when starting interplanetary or lunar missions from the planet surface. The program will compute the time to launch window and required launch heading. This program is the only one that doesn't compute any burn guidance data. A vessel specific ascent profile should be used to reach low orbit.
- Orbit Eject program is required when starting interplanetary missions from the orbit. This program is used in a combination with the other programs to convert the Escape information into burn guidance data.
