| Summary | 0000008: Artificial satellites computation | ||||
| Description | The calendar need to compute artificial satellites pass. The solution used in V2 in not free so we need to write something. Work is in progress, the project for the computation library is: http://sourceforge.net/projects/predictsatlib/ | ||||

Patrick: Did you ever retrieve the QuickSat FORTRAN source files? If not I have a copy of them on my other computer at home and would be glad to sent the ZIP file to you. Cheers, Geoff |
|
|
Geoff, Yes, I have the files and I start to work with them. The Fortran do not seem a problem but there is a few assembler files that do low level bios interrupt, this is OK for DOS but prohibited with Linux and highly not recommanded with Windows. So this take me more time to figure what this functions does and how to replace them in a portable way. |

Hello again. How far is the work on calculating artificial Satellites ? I know I Know its a lot work , but it would be very great if it would be possible again. Its a bit difficult to handle two versions of CDC to have this old feature and the new ones. MFG Smithsonian |

Satellite computation is ready with revision 1580 using Quicksat as in version 2, thanks to the new 32bit version from Mike McCants. It remain to find a solution for the Iridium flare. |
|
|
Patrick: I don't know if this may help, but there is a very nice Java utility to predict Iridium flares that I found on SourceForge. The URL is: http://iridiumflares.sourceforge.net/ Cheers, Geoff |
|
|
Geoff, Yes, this is the software I use on Linux this last years, it is very good. Maybe there is not enough interest to include Iridium flares to CdC now and this software is sufficient? |

Hello Patrick is it a license problem with iridflar.exe or is it because it is 16bit ? If its 16bit-problem how about using Dosbox to run it. Its a little emulator to run old 16bit Programs. Its free It works fine. Is easy to handle. I actually use it under Vista 64 to run old Quicksat.exe and Iridflar.exe Perhaps you can add it to Skycharts to run the 16Bit programs. Cheers Frank Schmidt alias Smithsonian PS:You really doing great work |

Hi Frank, Thank you for the suggestion, I don't know about Dosbox before. The main problem is that 16bit program do not run on Win64 and Wine. Quicksat as the same license problem and I can live with that. Skychart can be packaged without this program and the code is structured to allow for an easy replacement if someone want to write a free equivalent. I try Dosbox and it run iridflar on both Win64 and Linux but I have a few problem. First it is slow, even with setting cycles=max in the config file. Then using a recent space-track.org iridium tle file it complain about matching Iridium and NORAD number. Not a big problem but this remind us we use an unmaintained software. Most annoying is that even if flare prediction is written to screen there is nothing in the iridflar.out file, just "Illegal command: SORT." It look like it call the DOS sort command but this one is not implemented on Dosbox. So I copied sort.com from the Freedos project to the iridflar directory and by miracle it work. I try to implement it this way for Monday version. |

Revision 1581 add Iridium flare computation using Iridflar. It run natively on Windows 32bit and within Dosbox on Windows 64bit, Linux and Mac. http://svn.origo.ethz.ch/viewvc/skychart?view=rev&revision=1581 |
