Working on the camera to be animated. The 2 GAS clinders are now.

Now the cameras work

Tether set up. For some reason it will show the tss grap point.

Here is attached.

The tss has RCS

View of the TSS

Now we have the pieces to put together STS46 and STS 57. Want I need is a person to put them together and make the scenarios.

So that can be done. But it would just be a mesh. To make it into a vessel and hold cargo would take some coding,....

With this it makes sts 75 easy. But still how to do the tether? I think the way to go is just scale the tether and move the attachment. The Sat will just go straight up.

the tether is going thru the sat

The final distance was 850 feet or 256.08 meters. 2 factors are involved. 1 scaling and 2 moving the attachment point.

Animation proc goes from 0-1. So at 1 the attachment needs to move 256.08 meters

```
if (TETHER_out == 1) {// extends sat by scaling
TETHER_proc = TETHER_proc + 0.000390625;//1/256.08
if (TETHER_proc >= 1)TETHER_proc = 1;
}
if (TETHER_in == 1) {// retract sat by scaling
TETHER_proc = TETHER_proc - 0.000390625;
if (TETHER_proc <= 0)TETHER_proc = 0;
}
SetAnimation(anim_TETHER, TETHER_proc);
if (TETHER_proc == 0) {
boom_y = int_boom + (BOOM_proc * 12);
SetAttachmentParams(BOOM, _V(0, boom_y, 4.288), _V(0, 1, 0), _V(0, 0, -1));
}
if (TETHER_proc > 0) {
boom_y = int_boom + (TETHER_proc*256.08)+(BOOM_proc * 12); // move attachment for tether and boom
SetAttachmentParams(BOOM, _V(0, boom_y, 4.288), _V(0, 1, 0), _V(0, 0, -1));
}
```

```
static UINT SGrpANTTETHER[1] = { GRP_BOOM1E };//TETHER
static MGROUP_SCALE ANTTETHER(0, SGrpANTTETHER, 1, _V(0, -.753, 0), _V(1, 256.08, 1));//256.08METERS TO 850 FEET
AddAnimationComponent(anim_TETHER, 0, 1, &ANTTETHER, BOOMparent);
```

STS 46 released the 800 feet. STS 75 released the sat 12 miles.

cargo bay:

ready to deploy the TSS1

So the SAt was to be deployed 12 miles. But there was an issue so only 860 ft. I may make it go 12miles but stop at 860 ft.

The one thing I can get to work is the time advance.

```
double dtE = simdt * 0.0000005;
if (TETHER_out == 1) {// extends sat by scaling
TETHER_proc = ((TETHER_proc + 0.0000005));//1/256.08
if (TETHER_proc >= 1)TETHER_proc = 1;
}
if (TETHER_in == 1) {// retract sat by scaling
TETHER_proc = ((TETHER_proc - 0.0000005) );
if (TETHER_proc <= 0)TETHER_proc = 0;
}
SetAnimation(anim_TETHER, TETHER_proc);
```

if I do this:

` TETHER_proc = ((TETHER_proc +dtE));//1/256.08`

it does nothing

This is the guidance I have:

```
-30.000 =orbit(425,437,28.45,-1)
-6.0 =engine(0,100,6)
3.0 =engine(100,104.5,1.00)
30.0 =engine(104.5,72.00,5.00)
55.0 =engine(72.0,104.5,5.00)
512.0 =jettison()
```

This is what I get for the orbit mfd.

I saw where the orbit may have issues in mfd2015 and the newest d3d9. I have r4.11

The orbit value is too high and too circular for the Shuttle's launch profile, that's why the resulting orbit does not match the specified values....usually the initial perigee is only about ~100 km to allow the external tank to reenter the atmosphere quickly while the initial apogee is around 200-300 km. The orbiter's OMS engines then circularize itself to its desired orbit once it reaches the said initial apogeeNot sure if me or orbiter. I am setting up scenarios for sts 46. I launch and then accelerate time to the correct time. With 1 hour of the launch the shuttle reentering the atmosphere

This is the guidance I have:

`-30.000 =orbit(425,437,28.45,-1) -6.0 =engine(0,100,6) 3.0 =engine(100,104.5,1.00) 30.0 =engine(104.5,72.00,5.00) 55.0 =engine(72.0,104.5,5.00) 512.0 =jettison()`

From the sts 46 press kit:

Altitude: 230 n.m. x 230 n.m. (EURECA deploy) 160 n.m. x 160 n.m. (TSS operations) 128 n.m. x 128 n.m. (EOIM operations) Inclination: 28.5 degrees

230 nm =425.96km

So what should the orbit be? I wonder why the difference between d3d9 and default? I wonder if there is away to set the scenario with the different orbits?

All orbital values in the press kit are valid. You can make three separate scenarios out of it if you want to, or just simply pick one.So what should the orbit be?

But for some reason when MECO happens orbit is like -55 km x 450km.. too elliptic, I cannot figure out why.
