HACKING SATELLITES

MeteoFax32. It is a French program that is especially adapted  to use on computers embarked on board of the boats. An English version of this program will  available later. This program provides some information concerning the frequencies and the programs of the stations. 
The  address of the Meteofax32 site is:
 http://www.meteofax32.com
HamDream and WinDRM from HB9TLK is for Digital Transmissions of Voice and Data over radio with 2.3 to 2.5 khz bandwidth.
 First beta version of atpdec has just been released.
Atpdec is a NOAA POES satellite APT image decoder.
It's an open source program targeted for Unix platforms (in particular Linux). It lacks fancy graphical interface but focus more on image quality. (see http://atpdec.sourceforge.net/gallery.html for some examples
N0ONG WX Sat Kepler Editor is designed to work only with AMSAT (verbose) format elements.  Import the kepler file from AMSAT using the Open button. Everything other  than the weather satellite elemnts will be removed automatically. Now you can remove specific satellites by pushing the appropriate button. Pressing  the Save button will save the edited elements as kepler.dat.
The  program was written by 
Robert Boeckmann and runs on Macintosh OS X and OS9 and  is freeware

Aleex Greenland G7JGQ have been devoloping a excellent Satellite tracking program AGSatTrack, and is now available to others.
XAXERO come out with an Internet solution to the Weather Fax for Windows  Software for under $90. Please check the XAXERO page www.xaxero.com for more  details.
a new version of  WXTOIMG from Abstract Technologies New Zealand Limited is out that provides a  complete Windows 95/98/ME/2000/NTinterface in a self-installing archive.
The software is being supported under Linux, Windows, BeOS,  FreeBSD and AIX versions. a Macintosh version isavailable soon.
A new release of Mscan Meteo Fax now has integrate FAXNAVTEX and RTTY into a single program  called  Mscan Meteo Pro and is now available from the Mscan  pages
WeatherDecode v1.10WeatherDecode is a program for decoding of AAXX  and BBXX (FM-12) Meteo messages
A new free Windows satellite tracker programm called SatScape is now available. Satscape a specialised program that predicts where satellites are at the moment. You have also a World view, Horizon views, tabular list and a keppler update via your Internet connection.
An interesting and simple Satellite Tracker called LE SATELLITE FRANCAIS (LSF)
Alberto Casapa, Italy has written receiver control software for  different receivers such as Kenwood R-5000, Kenwood TS-790E, Yaesu FT 847,  AOR AR 3000 and AOR AR 800. for more info visit Alberto´s  Pages.
WXSat for Windows 3.1/95, decodes the signals in the APT format from NOAA, Meteor, Meteosat and GOES Satellites (AM) with a Soundcard.
WXSat can decode also FM-Fax for decoding facsimile-signals transmitting via shortwave.
WXSat works with the soundcard input so there is no external sampling hardware required. A cable between the receiver and the  soundcard input is enough. The program has also a good English documentation.
Oded Regev 4Z5BS from Israel has written a small program called TRACKER that allows the creation of maps that can be combined with images taken from NOAA satellites.
I have test it successfully with NOAA images received with 
WXSAT and JVComm. With it you can see country borders and sea/surface boundaries.
The program is quite small but it comes with the world map so it is about 3.4 Mb in total.
Here is a 
example from a NOAA 14 picture  decoded with WXSAT and added the country borders from the TRACKER program.
Several replies from test users, Oded send me a  corrected versionv1.1 . It should work better now. There is still a known bug regarding fast Pentium computers.
The ORBIT program will not run on fast computers (somewhere around 300Mhz and above). The only way to fix it is running a TSR program that slows the computer in DOS mode. You will probably find such TSR programs 
here . In the next version Oded will try to add it to the  release.
v1.1: Fixed bug in TRACKER.EXE with longitudes in the  range 100E-360E (=100E-0E)
Test users should download the upgrade from v1.0 to v1.1 here and copy the new files to the TRACKER directory

Julian Moss wrote a application called SatMon. With this utillity you can recording audio signals from weather satellites as WAV files to decode  with WXSAT or other programs.
David J Taylor wrote a decode program called SatSignalWith this  program you can demodulate signals from pre-recorded .WAV files. This program produce higher resolution images without the bent verticals resulting from Meteor decode with WXSAT.
David has also excellent satellite tracking software called 
WXtrack
Les Hamilton wrote a program called PALETTE to optimised the colors from images decoded with WXSAT.
PALETTE is a Windows 3.x/9.x compliant program wich operates on luminance bands within a BMP image  produced using WXSAT in conjunction with an image processing  program such as Paintshop Pro etc.
Hellschreiber, wich becomes worldwide a renewed interest is a very old mode wich was first introduced 1921 by Rudolf Hell.
The Hellschreiber is an early faximile communication , where only upper case letters were transmitted and received.
Hellschreiber is an asynchronous transfer mode where  the signal is discretely coded. This means two things:
The transmitter  does not tell the receiver how fast it transmits. It simply sends the message in it's own speed and the receiver must do it's best.
Hellschript is transmitted with either on or off signal. It was  hence easy to implement on available radio equipement. One simply connected the transmitter to where the morse key would be. Such signals  are very sturdy to radio noise. All unwanted frequencies may be filtered  away.
The hellschreiber was invented by Dr. Rudolf Hell in 1929 . It was used by the Germans during WW2 and some receivers was built by the British and Americans to intercept enemy communications.

Nino Porcino, IZ8BLYhas make a excellent Windows 95/NT based Hell program wich used the Sound  Card from your PC. You can download the program from Nino´s Home  Page
For more info on Hellschreiber you should first check Murray´s
ZL1BPU Pages wich is the best source on the net.
You can find Hellschreiber transmissions during weekends at 14063.5 KHz LSB (13:00 UTC mode Feldhell), also on 7037 KHz and 3580 KHz LSB (Tuesdays 20:00 UTC) for Europe.
Check also 3560 KHz LSB at 08:00-09:30 UTC for the "Hellraisers" Net or the DX Hell frequencies at 10140, 14063.5 or 21063.5 KHz LSB between 05:00 and 10:00 UTC.
There is a limited Beat version of Radioraft3 available now. Full version is expected in April.
New version of JVComm32 ready for download.The  current version is 0.97
Some new features: SSTV Robot 36 mode  for MIR reception, FAX TX in B&W, Scheduler (RX and TX) for FAX and SSTV, pre-select for different Sound Cards, Different Configurations and a lot of other usefull new features.
When more time I will make all FAX schedules for JVComm32 and will upload them on the "Schedule" page.
Les Hamilton, UK has launched a new Satellite tracking program called Footprint.
Footprint is program which displays the positions of an orbiting satellite and its footprint on a map of the Earth, updating its position and footprint every minute.
The program  can also provide reference tables of relevant ephemeris, A.O.S. and keplerian element data.
The program reads satellites' orbital elements from keplerian element files in standard NASA 2-line format, specifically  filtering out only those satellites belonging to the following classes :
NOAA, USA; Meteor Okean and Resurs, Russia; Sich,  Ukraine.
Download your copy of Footprint from 
Les  Hamilton´s Home Page.
FOOTPRINT has now a  two-map option. You can change the map to one centred on 180 degrees ( for  Australian users ).Also, the time and date routines have been improved.

A new satellite wefax image decoding software called SATFAX from John Lee Wilson W4UVV  is now available to the public.
It originally was written to accommodate the image noise dot saturation problem thet occurs when the  disered 40 kHz bandwidth.
SATFAX was designed for the occasional wefax monitor who wishes to use an ICOM R700, R7100, or AOR 3000A (also  other receiver/scanner that receive either 1691 MHz or the 137 MHz range)  and soundcard in his computer with wefax software to receive polar  orbiting and geostationary satellites.
What makes it so special is that in processing the wefax signal, the software compensates for the narrower bandwidth of receivers that typically have a 20 kHz bandwidth for wefax reception.
  MultiMode for Macintosh (new version).
