1  Project Apollo - NASSP / Support & Bugs / Re: Beta Modules? on: April 29, 2008, 11:45:01 AM
I've done another clean build to make sure this issue is real. RCS seems only to be working with the RHCs in DIRECT. Prior to update (release beta modules) I was able to make rcs commands via the CMC without direct on. To confirm CMC dap manuvers are also appear to have been broken.

I see the driving its rcs output channels but no firings.

In my test it seems to me that the RCS are working well ... also using DAP ... have start a mission from scratch or from an old scenario ?

In the last weekend I've build the module and I've tried a little Apollo 7.

I don't know if could be useful for some one but I've had a strange problem regarding the SM RCS.

Soon after the insertion at about 20 minutes after the lauch I've had a Master Alarm regarding the SM RCS B.

I've solved the problem activating the heater for the quad B, same issue on the D. (Temp very Low ...)

Ok,

Could may ask another question.

Someone could build the new MFD dll please ?
5  Project Apollo - NASSP / Support & Bugs / Re: Apollo 8 Testing using Apollo 8 Flightplan on: April 20, 2008, 02:50:38 PM
Hi all,

I'm flying the 8 and everything is fine and smooth. I'm arrived near the MET+20.

Two question: I've read in the Apollo 12 Fligh Plan that soon after the insertion they have setup an LVLH - head down attitude following an orbital rate and i think this attitude is the same for all the apollo flight. There's some way to setup this attitude in the current release ?

In the same Flight Plan before any P52 there's a "Manovre to 52 Attitude". Could some one tell me what is a correct P52 attitude and how yo set it up ?

Hi guys,

I'm still working on that. I'm working to have a single pdf with all the launch checklist; I'm in the editing phase Happy
7  Project Apollo - NASSP / Support & Bugs / FDAI Question ... on: March 28, 2007, 09:14:13 AM

Others are used only once for specific maneuvers, in fact there are unique ones for individual burns. These are computed in real time by the computer while in thrust programs (P40's) and can be activated by the P52 or P54 programs (option 1 "preferred"). The purpose of the burn specific reference frames is to display the zero reference (corresponding to 'wings' at level and "ball centered" in an aircraft) or when the spacecraft is steady at the desired burn attitude. In this case, if there is something wrong with the autopilot when the burn as started and the spacraft commence to drift in a wrong attitude, it's more easy for the astronaut to manually control the ship and return it to the right attitude corresponding with the 0 deflection from each axis.

Tryng some burn for the EOCA testing I don't understand how to obtain this FDAI display ... I  made my P52 Option 1 but the FDAI is not "ball centered".

In which way i have to set the FDAI related switch ?

Thanks Guido

9  Project Apollo - NASSP / Support & Bugs / CMC Update Excel Sheet for Excel 2007 on: March 27, 2007, 08:29:49 AM
Hi,

Regarding the DEC2OCT Excel 2007 issue I've tested that the Excel Sheet provide in the doc folder have trouble related at the Excel 2007 function called DEC2OCT.

So I've rename the original function in "irOCT2DECT" and I've made the change in all the sheets.

Attached at this post the 2007 version of CMC Update Sheet. Once opened you have to activate macros

Cheers Guido
10  Project Apollo - NASSP / Support & Bugs / Apollo 7 S-IVB Cutoff on: March 26, 2007, 05:09:51 AM
Hi all,

In this weekend I've had some moments to launch my own Apollo 7.

Everything is working fine following, I've only a little question.

During the launch the S-IVB Cut Off at (if I remeber well) +08:35. In the Apollo Reference Source Book the S-IVB cutoff  is at +10:14.

Why this difference ?

11  Project Apollo - NASSP / Support & Bugs / Re: P52 Question ... on: March 23, 2007, 04:55:20 AM
The last question ...

How is possible to recover this bad IMU ? Is needed to update the REFSMMAT it self or via the P52 is possible to realign the IMU ?
12  Project Apollo - NASSP / Support & Bugs / Re: P52 Question ... on: March 21, 2007, 05:39:37 AM
Could you confirm that this sequence is right ?

After marking the star

F50 25
00016

PRO

F01 71
[Same Star Code as the previous F01 70]
PRO

F01 70
[Second Star Code]
PRO

And it begin the second mark sequence ...

It's Ok ?



13  Project Apollo - NASSP / Support & Bugs / P52 Question ... on: March 21, 2007, 04:39:06 AM
Hi all,

Last night I've try using the EOCA scenario provide by Christophe some P52 using the preferred option and the Ops3 REFSMMAT.

Everything is working well, but when the CMC drive optics to find the select star I found it orizzontally match the cross in the SCT but vertically placed at the top of the SCT.

I've centered with the SCT and mark the star using SXT.

The result of the two star mark is a poor +01598  Embarassed

This mean the the IMU is out of his alignment or that I've made something wrong in the mark procedure ?

How to realing the IMU in the best way ?

This is the Microsoft Page about DEC2OCT:

http://office.microsoft.com/en-us/excel/HP052090551033.aspx

When I try to open CMC Update Excel automatically change the DEC2OCT function with the internal and I don't any chance to change it ... Bangs Head
15  Project Apollo - NASSP / Project Apollo - NASSP Development / Re: Orbital Calculator on: March 20, 2007, 11:37:50 AM
Thanks a lot ...

Taking a look to the CMC Update Excel Sheet, using it with Excel 2007, Excel said there is already an embedded function call DEC2OCT.

Seems that this cause some trouble to your work ...
