The current version is IMFD 5.1m released on June 26, 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 Moon 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.
Setting values from keyboard
You can setup values in many formats from the keyboard by pressing [Set] button. The exponent format can be used like ”12.4e3” or ”11.45e-2”. The exponent can also be replaced by a letter like ”12.4k” or ”33.2M” or ”22.2G”,where k is equal to ”e3” and so on. ”d”=day will multiply the input value by 86400. ”h” is equal to an hour and ”a” is one astronomical unit.
Time in GET and UT
It is possible to enter dates in UT format like ”UT 14-nov-1969” or with the 24h clock ”UT 4-nov-1969 17:45:21.1” Used names for the months are Jan, Feb, Mar, Apr, May, Jun, Jul, Aug, Sep, Oct, Nov and Dec (not case sensitive). IMFD 5.0 is supporting GET (Ground Elapsed Time). This feature can be activated from the configuration page. Also the date of launch must be specified. You can enter data in GET format by pressing [Set] button and entering the time ”GET 120:34:56.7”. When flying with AMSO IMFD will receive GET time via interprocess-com link.
Sharing Flight Plans
A Single flight plan can be ”shared” between multible MFDs by seting the IMFD into the remote access mode by pressing [PG] button in main menu. Popup window will ask about an ID code of the MFD being accessed. The ID codes are shown in a top right corner of the MFD. The flight plan will stay resident evenif theMFD containing the flight plan is closed so the other MFDs can still access into the plan. If you want to disconnect the MFD from others just setup an invalid ID. For an example the ID of the MFD itself. When using multible instances of IMFD they must not access in each other. For an example when using two instances only one of them can use remote access.
Some of the programs are supporting display 3D rotation via mouse. Hold down shift and Z- or L-keys to rotate the display. Only the Left and Right MFD displays can be rotated. 3D Rotation is not supported by all programs.
