General Astrodynamics Library v0.5
by Paul Willmott 10 Jan '09

10 Jan '09

Version 0.5.0 of the General Astrodynamics Library has been released. It can be downloaded from the project website here: http://homepage.mac.com/pclwillmott/GAL/index.html Updates in this release: ** Additional routines added to Kepler sub-library ** Planetary and Moon rotational elements added ** Reference frame routines for planets other than Earth ** Acceleration due to Solar Radiation Pressure added ** Acceleration due to Atmospheric Drag added ** Sun occulation routine added for satellite eclipses ** Support for Harris-Priester Earth Atmosphere Model ** Mars date and time routines added ** Ellipsoid models for the planets and the Sun added ** Earth satellite rise/set routine added. The Reference Manual will be updated shortly. The General Astrodynamics Library (GAL) is a numerical library for C and C++ programmers. It is free software under the GNU General Public License. The library provides a wide range of astrodynamical routines such as ephemerides, earth orientation, and orbit propagation. There are over 260 functions in total with an extensive test suite.

Re: Does working through ISS repeater qualify for 25th Ann Certificate?
by Mike Ryan 10 Jan '09

Right. Amusingly enough all respondents pointed me to the exact article I referenced in the first place. My question is around interpretation of the article. Repeaters are certainly mentioned, but it doesn't say if a contact through the repeater to a terrestrial HAM would count or not. In this case you're not communicating "with" the ISS, but communicating back to earth "through" the ISS. You're not actually QSOing with someone on board which is more coveted. For lack of clarity, I suppose I could just submit the request and see what happens.

WD9EWK @ hamfest
by Alan Sieg WB5RMG 10 Jan '09

10 Jan '09

Just worked Patrick WD9EWK via VO-52, with an audience at the hamfest. I had some local noise on the downlink, and hope my uplink was sufficient. His signal was good, and he had several others calling . . .

Does working through ISS repeater qualify for 25th Ann Certificate?

The following mentions availability of a QSL certificate for contact with ISS for the 25 anniversary. Is a QSO made with another terrestrial HAM via the cross band repeater eligible for this or must the contact be directly with someone on-board? http://www.rac.ca/ariss/oindex.htm Mike WB1AAT

Equador on AO-7
by Glenn Miller 10 Jan '09

10 Jan '09

I heard an HC7? in grid FI07 on AO-7 last evening (Jan 9) around 0318Z. I missed his call sign, but copied his grid before he was LOS. Has anyone else heard or worked him? 73 de Glenn AA5PK San Angelo, TX DM91 _________________________________________________________________ Windows Live™ Hotmail®: Chat. Store. Share.

SatPC32 & Multiple Sats Display
by Sebastian 10 Jan '09

10 Jan '09

Some time ago, the ability of SatPC32 to display multiple satellites stopped working for me. I uninstalled the program, and reinstalled it, and have the same problem. Pressing on the little M on the upper left doesn't seem to do anything. It will go from M+ to M- but that's all it does. So can someone give me an idea if there is a registry setting or a file that needs fixing? I'm using Windows XP with SP3. 73 de W4AS Sebastian

next pass of AO7 I will be looking to stretch the footprint a bit toward South America. Downlink of 145.958. If any YV's etc are around I will be there. 73 Bob W7LRD Seattle cn87 -- "if this were easy, everyone would be doing it"

What frequency do I use?
by WB2LLP 09 Jan '09

09 Jan '09

As of late Thursday afternoon the ARISS site was showing the 145.99/437.80 pair in two locations. Unfortunately one location was the inverse of the other. Which was correct? If I had packed up my equipment and gone out to work the ISS repeater, and heard nothing because I picked the wrong frequency pair I would come home rather frustrated/irritated. AO-51 is a wonderfully capable machine and the controllers are doing a wonderful job of changing the satellite capabilities which encourages the newcomer to improve his station and the old timer to dust off his AO-40 hardware. Unfortunately, for any number of reasons, the satellite capabilities and frequencies have been changing rather quickly. If a user does not check the AMSAT website, and the AMSAT BBS before trying to hear the satellite he risks hearing nothing and getting frustrated thinking that there is something wrong with his equipment or his understanding of the process. I would like to suggest that the controllers give some serious thought to more stability in the AO-51 configuration. Maybe the configuration periods should be at least 2 weeks so that people have a better chance of knowing the hardware and frequencies of the satellite. Also, the person trying a new configuration has a few consecutive days to get the bugs out of his station. Additionally, make sure the information presented on the AMSAT and ARISS sites is correct. 73 de WB2LLP Gene
