1  Project Apollo - NASSP / Programming / Re: Getting Involved on: December 15, 2010, 10:42:24 AM
I have been trying to do exactly that for a while now, and now am on a month off from work so finally giving it a proper go!

There are a few NASA technical notes that have been very useful in figuring out numbers for the coelliptic sequence (had them so long now, am not sure where they came from! Can email across if you like).

My knowledge is limited so I have just been using the historic times and altitudes, figuring out a solution in IMFD and transposing the data across to use in the AGC. What I am trying to figure out now, is how to use the AGC programs 31-35, and how it all fits together.

Well anyway, feel free to PM me if you are interested in collaborating, or want any of the docs.

Regards,

Alex
2  Project Apollo - NASSP / Support & Bugs / Apollo 7 VAGC CTD on: March 30, 2010, 05:53:43 AM
Just fired up the Apollo 7 VAGC scenario, and get a CTD whenever trying to select the optics panel in 2D cockpit. I did a CVS update and reinstalled January 04 modules and same problem occurred. Have not tried a a clean install yet, (next thing on the list!) but thought It was worth mentioning anyway.

Regards,

Alex

Yet another strange occurrence! Attempting to restart the CMC, and following the steps detailed in AP8 mission flight plans, I get hung up at coarse alignment of the ICDU's. The NO ATT light will not extinguish maybe due to my misunderstanding the procedure steps, but equally might be due to the issue above!

Sorry for not posting this for a few days. Normal life intervened somewhat.

The scenario contains the conditon after completing both clock and state vector updates, and getting the 'V37 not allowed' error.

Am home for a few days now so will try the CMC restart procedure.

Thanks again!

Thanks for your input guys.

Did a manual state vector update right after correcting mission time, and still getting program alarms. Alarm code is: 01520

Will try a CMC restart next, see if that helps!

Something strange has ocurred...... What?

Carried out the uplink as described above, times all updated perfectly. Now came to run P30 and get a PROG light every time. Tried to run the alignment programs as well with the same result. Any ideas?

Haven't got time now but will try a computer reset and manual state vector update when I get the chance.

Tried using ProjectApolloMFD and worked perfectly!
Yeah, I think I did pull the cb's before to allow a little time accelleration. Guess that would cause the clock to reset!   Duh!

Thanks for your help!

Hi Guys, I have a small problem thought I would ask for some advice!

Have been running an Apollo 8 scenario using the latest flight plan over a period of weeks, by saving the flight every few hours. Came to do the final MCC using the SPS, and always got TIG +59 59 when running P30, even though the GET input was for less than 1 hour ahead. I thought that there might be a discrepancy between elasped time in the AGC and the mission timer. Sure enough they appeared to be off by about 36 hours. I then tested the theory by using my GET calculated for P30, minus 36 hours and got the result I was expecting, TIG -45 etc.

My question is: Is it possible to manually update the clock, either through the .scn file or the AGC itself?

Kind Regards,

Alex

Thanks for your reply.

Yeah I have been trying that scenario but the booster was behaving very strangely after loading, ie just falling back to earth from the launch tower and tumbling around! I assumed thats why the scenario was broken!
However I forgot to deactivate Meshland, and that seems to do the trick! Problem solved!  Happy

Hi Guys,

I have recently started to have a go at flying Apollo 8 vAGC using the new checklists, but am having a problem finding a scenario that will work. I have updated CVS several times but still can find nothing.   Confused

Any help for a noob would be much appreciated  Happy

11  Project Apollo - NASSP / Project Apollo - NASSP News & Discussion / New Beta modules request on: January 25, 2009, 01:11:50 PM
Dear All,

Have been a lurker on this forum for a number of years, with a keen interest in Apollo but without the time to really get stuck in and get to grips with all the new features! (Which be way are excellent! Amazing work guys! Particularly the new checklists which have really helped me learn!)
Now I have some time, my request is for a new set of download-able modules at some point? I don't have the facility to build them myself unfortunately!

Again thanks for the great work guys, really amazing! Thumbs Up

Kind Regards

Alex

Hi there!

Whilst you are on the subject of Apollo 7 I have a couple of quick questions? I have just come back to Apollo after quite a while out of the loop, and thought AP7 would be a good place to start! My main question is, are the DAP/rendevous/reentry features implementated in VAGC, or the Simple AGC modes?

Regards,

Alex
13  Project Apollo - NASSP / Project Apollo - NASSP News & Discussion / Re: Project Apollo's dead? on: November 18, 2006, 01:03:09 PM
Hi guys,

Ive been following Project Apollo from the start, but unfortunately havent been able to contribute anything (airline pilot training taking up 150% of my time Happy
Just my two pence, but I really enjoy watching the various systems being developed and then finding time to try them out myself. I think you should release a 'package' with various working systems, and then release updates as you go along.
Anyway, whatever happens hats off to you guys for producing Project Apollo!

Cheers

Alex
14  Project Apollo - NASSP / Support & Bugs / Re: Strange Problem with TransX & ApolloMFD on: September 17, 2006, 08:37:00 AM
Thanks for your help yet again!

Sorry I should have been more explicit! It is transX that shows a difference in dv of +100 -100 ms. After looking into this in more detail i have noticed that the figure transX gives for deltaV seems to fluctuate up and down during the course of one orbit. I haven't noticed this happening before, (and in the past i have been able to set up very accurate TLI burns) so Im a bit perplexed!

Thanks 

Alex
15  Project Apollo - NASSP / Support & Bugs / Strange Problem with TransX & ApolloMFD on: September 16, 2006, 12:58:44 PM
Hello Again,

At the moment I have a couple of very curious problems. Im using the combination of TransX, and ApolloMFD to figure out my TLI burns, but just cant get a good result anymore:

1. When I use the figure generated by TransX with Apollo MFD, I always end up with +100 or -100ms deltaV.

2. The second, is probably just my own ineptitude, but I'll mention it anyway! I can't seem to get satisfactory results for all TLI parameters anymore. Usually accepting a 30 degree off plane angle, just to get anywhere near the moon! Is nothing to do with Project Apollo development as such, but if anyone out there could give me a hand Id be very happy!

Thanks!

Alex
