Updated gmat_startup_file.txt

Parker, Joel J. K. (GSFC-5950 — 2012-06-05T17:46:17

All,

I just committed a new gmat_startup_file.txt that re-enables all plugins that were disabled for the release. Be aware that your startup file may change the next time you update!

Re: GMAT with Python

Parker, Joel J. K. (GSFC-5950 — 2012-01-11T16:42:31

Hi Josef,

About Python, I don't personally have experience using it with GMAT. The usual method would involve using Python to write or edit a GMAT script, then running the GMAT executable with the script file as input (for example using os.execl()).

There's actually support in the SVN repository for a limited C interface that will let you run a script or use GMAT's force models with your own integrator. This could be used from Python's ctypes library, perhaps. The API is here: http://gmat.sourceforge.net/doc/nightly/capi/_c_interface_functions_8h.html. It's not documented from a user perspective, so let me know if you're interested in this option and I'll give some advice.

The 2GB repo size is mostly because of large data files in the trunk/moredata directory. At the very least, you'll need trunk/application, trunk/build, and trunk/src build a working copy (plus some external libs). We have some VS2010 instructions here that may be of help on other platforms as well: http://gmatplugins.sourceforge.net/blo

GMAT with Python

Koller, Josef — 2012-01-11T16:14:02

Hi GMAT developers,

 I'm new to GMAT and I have some basic questions:

1) Does anybody have experience in how to call GMAT routines with Python? I know matlab would be an alternative but I'd prefer Python for various reasons.

2) when I download the src trunk with svn, it gives me over 2GB? This seems a bit much.  Do I need the other files or is everything in gmat/trunk/src sufficient to compile etc?

Thanks,

 Josef

New leap seconds kernel

Parker, Joel J. K. (GSFC-5950 — 2012-01-06T01:31:35

This is from an email from NAIF:

"The International Earth Rotation Service has announced a new leap second will take effect at midnight before 01 July 2012. NAIF has created a new leap second kernel (LSK) that is now available from the NAIF server at the usual location: ftp://naif.jpl.nasa.gov/pub/naif/generic_kernels/lsk/  or http://naif.jpl.nasa.gov/pub/naif/generic_kernels/lsk/.  Separate versions for  Unix/Linux/Mac (naif0010.tls) and for PCs running Windows (naif0010.tls.pc) are available. 

You may begin using this new LSK at any time prior to 01 July 2012--it is fully backwards compatible with the current LSK. 

You MUST switch to this new LSK prior to 01 July 2012 for any time conversions involving epochs after that date."

Developer docs online

Parker, Joel J. K. (GSFC-5950 — 2011-11-23T16:11:13

I posted the developer docs built from the 2011-11-22 nightly on our documentation page here:

http://gmat.sourceforge.net/docs/

Darrel, is "Engine" a good name for the base docs link? I was playing with calling that link "Base", "GMAT Base" or "GMAT Base Code" also.

Next up is to reconcile the C API docs with the base/gui style and add some of the other plugins.

Poll: Features for a GMAT toolkit?

Parker, Joel J. K. (GSFC-5950 — 2011-11-07T13:23:10

Hi all,

Next year, we'll be developing a C-language interface to GMAT's base code and a user-friendly MATLAB toolbox to use it. This will make GMAT into an astrodynamics/mission design toolkit, meaning that you'll be able to use pieces of GMAT programmatically, without loading up the interface. Similar toolkits already exist in the form of AGI Components and Orekit, but these have limitations we're trying to avoid.

What we need is some feedback about which pieces to expose this year (we can only do a few). This may include things like coordinate system conversions, time system conversions, orbit propagation, etc. We also need to know things like what platforms you'd want to use and any special needs you have (performance? compatibility?).

So please, if this is of interest to you, reply back and let me know what you'd like to see!

Thanks,

Updated training doc

Parker, Joel J. K. (GSFC-5950 — 2011-11-04T14:56:34

Here's another update of our training document style. It has a complete table of contents this time, with the exception of the last tutorial Steve is working on.

The text hasn't been scrubbed, but this gives a sense of the latest look-and-feel.

I appreciate all comments!

(To respond to one of Wendy's comments: there's a lot of blank pages because this is formatted for two-sided printing. Some pages are standalone and have blank backs.)

Tom,

Yeah, I was wondering how to add in status updates. Maybe splitting up the agenda is the appropriate way to go.

For GMSEC, did the minutes recorder type directly into the document during the meeting, or did he/she jot down notes and input them later?

Hi Joel,
Thanks for doing this.  It looks good to me.  

I was going back through my GMSEC meeting minutes and the only thing I might add is that we broke up the Discussion into the agenda parts, attributed them to whomever was reporting about them and then divided that into Accomplishments, Plans and Discussion.  So, for example, if we had GMSEC VCR in the agenda, in the Discussions, we had:

GMSEC VCR - Tom
Accomplishments:
*Updated GMSEC VCR SRS inspection worksheet
*Created RTM for GMSEC VCR

I put the new meeting minutes template online and created a new wiki page here:

http://gmat.ed-pages.com/wiki/Meeting+Minutes

One small issue is that Google Docs doesn't let you make a true template, so it's just an empty document that you'll need to make a copy of each time.
