I got back to earth correctly with the DG-2 right on the runway, Capa Canavrel.......
I can't belive it - next target ISS ! And advices ?

Few corrections
*And* advices = any
*Capa* Canavrel = Cape

the alignment and transfer MFD's are your friends for station intercept.

If ill just use the GD computer ill fet there (if ill excute a manual burn by the data)

Use the Align MFD to target the ISS.
Take off when you are at the AN or DN.

Look at the Map MFD and it will be easy to understand why :)

Use the DGII's computer to get to orbit.


Use Orbit MFD to get to the right altitude.

Then use the Align again to get the alignment perfect. (there is a section in the Orbiter manual on
that)

Then use the Sync MFD to arive at the same time. (with training you can actualy HIT the ISS :))

Tune the Com MFD to the ISS transponder.

Use the HUD (Dock Mode) to eliminate velocity difference.

That's all, folks 8)

PS: The manual explains all the MFDs pretty well.

i havnt read all the manual, and i figured it out, but i couldnt figure the sync MFD out so i used the
transfer MFD to calculate burn point and dV, got within visual range and proced to match rV with it.
same process really.

The Sync MFD shows the time difference at the reference axis.

The easiest way is to set the refference to "Intersect 1" or 2 (untill you understand it better)

Start by establishing a circular orbit LOWER  then you'r target, and align you'r orbit (RInc less then
0.5).

Then you burn prograde to make you'r orbit eliptical.

When the orbits intersect the reference axis shows where the time difference (DTmin) is measured.

Watch the DTmin number. Get it as close to zero as possible. (use the translational thrusters to
get it pefect)

Two of the numbers on the right are yellow. This shows the orbit when you are closest to the
target.

The picture in the manual shows that you reach the Intersect 1 in 7545 seconds on this orbit (orbit
0).
The target reaches the same spot in 2044 seconds on this orbit (orbit 0), but in 7544 seconds on
the NEXT orbit (orbit 1).
The time difference (DTmin) is 0.26 seconds. If you use time accel this drifts a bit, but you can
adjust it when you are at Periapsis.

Then you wait untill both the yellow numbers are at the top (orbit 0)

When you are close to the Ref. axis you use the HUD in dock mode to match the speed to the
target.
