1 a. If you want to test the SatPC32 programs you can download the present German or English version 12.8c. The program will be installed as Demo version. The only restricition of the Demo: The user's QTH coordinates can not be stored for the main program SatPC32.Exe, but have to be entered at every program start.
Further, the previous program version 12.8b can still be downloaded (fig. 8 below).

Unzip the downloaded file into an empty folder on your HD and proceed as described in the file "Read this before your download .....", see above. .
IMPORTANT: Under Windows Vista and Windows 7 (32- and 64-bit) right click on the filename "setup" and from the list that opens choose "Run as administrator".
Updating of older program versions
Program version 12.8c can be installed into the same program folder that contains the older program version (12.8 ... 12.8b). Unfortunately, the Installshield setup program of SatPC32 V.12.8c deletes all program data of versions. 12.8, 12.8a or 12.8b, however. Your personal settings will be lost. The program 'DataBackup.Exe' allows you to easily save your settings via mouse click and then to restore them after the installation of V.12.8c is finished. The program 'DataBackup.Exe' is contained in the SatPC32Demo ZIP files that can be downloaded with the links above.The files contain also the file UpdateInstruction.txt Unzip the downloaded file into an empty folder on your HD. Read the UpdateInstructions.txt or click on Update Instructions and run DataBackup before you start the setup program.
After V. 12.8c has been installed DataBackup can also be started
from the SatPC32 menu "Programs". Add a line "DataBackup"
(without quotation marks) to the list of the auxilary. file "Program.SQF".
The file can be opened and edited from the SatPC32 menu "?", "Auxiliary
Don't install SatPC32 12.8c over 12.7 or older versions but into a completely empty program folder!
Up to V. 12.7 the program stored program data in the SatPC32 program folder and several sub folders. That can cause problems under Windows Vista and Windows 7, however. Beginning with V. 12.8 the program therefore stores data in a data folder 'SatPC32' and several sub folders in a Windows system folder for application data. For detailed hints read the Update Instructions, please.
With possible questions or problems read the FAQs file, please. The file contains answers to frequently asked questions - for example on how to update Keplerian data - and solutions for known problems.
The file that can be downloaded with this link will continuously be completed and therefore possibly be newer than the file that comes with SatPC32.
5. More Downloads
a. The Space-Track TLE Retriever by Dr. T.S. Kelso is a very comfortable tool which allows users with an active Space Track account to easily download Space Track data sets and use them to generate standard CelesTrak data sets that can be used with SatPC32.
Downlod the SpaceTrackTLE-Retriever
HalloKepler by Gerd Riesner, DB3DH, is a similar comfortable program.
b. DDESat32 Vers. 12.8 (full version).
DDESat32 is an interface program to be used with Wisp32. The program is in German but easy to understand by everyone (see the description and screenshots on the page 'Software').
To install the program unzip the downloaded file into an empty
folder on your HD. Start the setup program in that folder and follow the
For detailed information read the DDESat32 Manual (English).
Download DDESat32 for use with SatPC32 V. 12.8 and later.
If you are using SatPC32 12.4 ... 12.7 download the older version DDESat32_12.4.
c. The program AOS.Exe (DOS-version) can be downloaded (for free), either in German or in English. The program creates lists in chronological order of the audibility times of satellites.
AOS V. 3.0 (German) (159 K)
AOS V. 2.5 (English) (68 K)
d. SuM programs
The SatPC32 V. 12.8c setup program installs these programs automatically.
e. ServerSDX for Yaesu compatible azimuth
No longer required! The new ServerSDX supports also azimuth-only systems.
Beginning with program version 12.8b the setup program installs TimeSync automatically. It can be started from the SatPC32 menu "Programs".
Satellite operation requires a highly accurate system time. TimeSync synchronizes the PC's system clock with one of the internet time servers. This way you can ensure that the PC's system time is accurate.
If you run an older SatPC32 progam version you can download TimeSync with the link below. Extract the TimeSync setup program from the downloaded ZIP file and save it somewhere on your HD. Start it by double clicking on the file name "TimeSyncSetup.Exe" and follow the instructions.
IMPORTANT: Under Windows Vista and Windows 7 the setup program must be started with the option "Run as Administrator". To do so right click on the program name and in the list that opens choose that option.
The setup program generates an icon (shortcut) on the desktop. To start TimeSync double click on the icon. For further instructions click on the "Help" button in the TimeSync program window. .
g. Buffer interfaces
Buffer interface for Labjack U12
Buffer interface for Labjack U3
For rotor control with the Labjack U12 and U3 an interface is required that buffers the output terminals of the U12 and U3 vs. the rotor control box. Unfortunately the readymade 'Piggyback' from NLSA is no longer available. With the 2 links above you can download the schematic diagrams of this homemade interface which also show how to connect it to the U12 and U3. The interface can easily be duplicated, the only component is a ULN2003AN. I don't have a PC board, however. I mounted the chip and the 8-pin DIN connector on a small piece of conductor board, see picture.
How to add data for new satellites
The data files that come with SatPC32 contain data for many important radio amateur satellites. Data for other satellites must be added manually to the existing data files. For detailed hints see the "Tutorial" by Wayne Estes, W9AE. It can be displayed from the FAQs file, sect. 1a.
With the link below you can download data of the lately launched SO-67 and HO-68. The data can be added to the existing data files Doppler.SQF, SubTone.SQF and AmsatNames.txt.
