[Question] Can IMFD be used to the voyager?

[NOMAD]

I use the TransX,but sometimes it is difficult to launch the spacecraft in a correct trajectory.Can IMFD be used to the voyager?

[tblaxland]

Please clarify your question. Do you mean: can it be used to plan a flight like that used by the Voyager probes? Or something else?

[Tommy]

Yes IMFD can be used to fly the voyager flightplan, if you use the historical dates or pre-calculate another launch window. Since you have transX experience, I'd consider using IMFD to set up the first transfer (to Mars) so you can use it's launch program, then use TransX for the rest. Keep in mind that IMFD's map is more accurate than TransX, and can be used to "fine tune" a trajectory fairly early, minimizing the dV required.

Well I got good gravitational assistances using transX and IMFD, I use trans x to adjust the orbit around the Sun (orbit of Hoffmann ) through the planet to carry out assistance.

MethodPERSEUS

The escape of the origin, planet has previously been achieved already (although you can try to make the adjustment from the exhaust, but gives more errors)


As you know transx works as Windows or phases of flight
Setting the first window with reference on the planet to us Dara momentum orbit the Sun.

WE DO THE ADJUSTMENT BY MODIFYING THE VARIABLES OF EACH STAGE

And now we see the lineYellow DASHEDof the stage 1 VARs stage 1 this is the correct initial trajectory towards a third planet with assistance in a second planet.




Eye to the data:ENC : 44047.4255 MJD

And here how to fine-tune the trajectory


Enc: MJD 44047.4255 this fact as I have been A ImfdIs the TIME that it takes to intercept the body
AND MARK FROM OUR POSITION THE ORBIT REQUIRED

In IMFD[menu] – [course] [target] Jupiter [next] to GET (mode MJD) [SET] set value introduces 44047.4255


Is drawn the orbit required in IMFD and now using the magnificent autopilot IMFD [AB] (auto) (Burn) we carry out the manoeuvre power to adjust the orbit
And we are already en route to our gravitational assistance

So I normally used with good results although adjust the orbit in TRANS-x is a cansino at first, but it is incredible in your trajectory, prediction I have already come all the planets in the solar system .
Windows to the gravitational assists computation them with orbita program .

Try stretching to have one angles and different dates window a MJD date to the *.scn scenarie file.
