The programs SatPC32.Exe (in the following: SatPC) and Wisat32.Exe (in
the following: Wisat) calculate the tracks of earth orbiting
satellites. The calculations are based on the SGP4/SDP4 model, the
results therefore are highly accurate. Both programs are included in
the SatPC32 program package.

SatPC32ISS.Exe (in the following SatPCISS) is a special version of
SatPC32 for radio amateur operation via the ISS. The program provides
“In-Band” frequency control with several radios. While “normal” amateur
satellites use different bands for uplink and downlink both frequencies
of the ISS are in the 2m band. The “normal” SatPC32 switches the radios
into satellite mode to allow full duplex operation (transmitting and
receiving at the same time). Therefore uplink and downlink must be in
different bands.

SatPC32ISS is also included in the SatPC32 program package.

SatPC displays the audibility-areas of one or several selected
satellites within a world-map and shows the results in text-lines below
the map. Wisat represents the satellite positions in real-time in
list-form. Both programs update their calculations continuously in
steps of one second. The differences between SatPC and Wisat result
from the absence of the graphic output in Wisat.

SatPC and Wisat steer the antennas and radio frequencies (CAT) for
Doppler correction. Both programs allow multitasking with programs that
provide data transfer with satellites like Wisp32. SatPC32 and Wisat32
then will take over the antenna- and frequency-control. The automatic
switching on a satellite works synchronized with the data-program.

The automatic Doppler correction also works with ssb transponders like
FO-20, FO-29, AO-10, AO-40.

The antenna-control steers the AMSAT Rotor Interface and the
ready-appliance IF-100.

Further, the following interfaces and controllers are supported:
RIF-PC ( Orbitronic),
WinRotor32 (Funkbox , Parallel port and USB version),
HalloRotor ( DB3DH),
Fodtrack-Interface (XQ2FOD),
Kansas City Tracker /Tuner (KCT/T),
Yaesu GS-232 and compatible interfaces (G6LVB-Tracker, AlfaSpid,
DL7AOT, CX6DD, ST3 (FoxDelta), SatDrive),
SAEBRTrackBox (N8MH),
Satellite Tracker Mini, Junior, Senior (W0LMD),
SatEL interface (Satellite Electronics),
Labjack U12 (USB Controller / PiggyBack (NLSA),
Labjack U3 (USB Controller, see page ‘Downloads’),
LVB Tracker,
AlfaSpid controller,
ST1 controller (VU2FD),
Pro.Sis.Tel.controller (see page ‘Downloads’),
M2 RC-2800 Rotoren

Driver programs for these devices are included (or are delivered with
the hardware), which take the data for rotor- and CAT control via DDE
from the main-programs SatPC32 and Wisat32. At the end of this section
you will find as an exemple a screen copy of the driver-program for the
KCT (ServerKCT.Exe).

The frequency- and mode-control works with the following radios:

Yaesu transceivers FT-736R, FT-847, FT-817, FT-857 and FT-897,

Kenwood transceivers TS-790E/A and TS-2000,

ICOM transceivers IC-820, IC-821, IC-910H und IC-9100,

ICOM receivers and transmitters, that work with the same cat protocol
(i.e. IC-275, IC-475).

The programs will work also with serveral other models, this has to be
tested, however.

In VFO mode the radios supported by SatPC32 (except the Yaesu FT-736R,
s. below) can be tuned with the Vfo as well as via the PC mouse and
keyboard in selectable frequency-steps of 20, 100, 500 Hz, 1 KHz and 5
KHz. Tuning with the Vfo is the most comfortable way, tuning via the
PC, however, allows fast and precise QSY, which can be helpful, when
QRM is coming up on the frequency.
The Yaesu FT-736R can be tuned only via the PC as described above.
Since it’s Vfo frequency can not be read, it can not be tuned with the
VFO knob.

To steer the aformentioned rotor systems the program package includes
several little “driver” programs. These programs are automatically
started and closed by the main program. They receive the rotor data
calculated by the main program via DDE, convert it into the format of
the particular interface or controller and output it to the PC’s ports.

The output of the CAT control is sent directly to a (physical or
“virtual”) serial port (it can also be sent to the KCT Tuner thus the
radio can be steered via the serial ports of the KCT/Tuner).

Further, the program provides a constantly active DDE interface, which
allows third-party-programs to receive the antenna positions,
frequencies and modes calculated by SatPC32. This interface -in example
– can be used by CX6DD’s WispDDE. Thus all hardware supported by
WispDDE can be controlled also by SatPC32.

A particular interface allows cooperation with Uni_Trac 3000. Therefore
all hardware supported by that program can be steered with SatPC32, too
( beyond the devices supported by SatPC32 itself).

The programs run on IBM-compatible PCs under WINDOWS 98, ME, Windows
NT, Windows 2000, Windows XP, Vista and Windows 7. As far as I know
SatPC32, Wisat32 and DDESat32 ( see below) are the only 32-bit-programs
at present time, that provide rotor-control with the IF-100 and RifPC
and a rotor- and frequency-control with the Kansas-City-Tracker/Tuner
on WinNT 4.0 and Windows 2000.

The programs support the 120 dpi fonts (available at screen solutions
of 800 * 600 or higher), but not user-defined fonts or the new 144 dpi
fonts invented by Windows 7. For solutions of 800 * 600 and higher
additional bit maps are included. With these maps SatPC fills the
screen at 1024 * 768 for about 90%.

The programs can show times in UTC or alternatively in the observer’s
local time.
