Lite punkter

*Solen väldigt aktiv

*PW-SAT cubesat med transponder

Det här verkar att bli en verkligt trevlig satellit från ett universitet i
Polen. Lite udda är att den har upplänk 145.900 FM och nedlänk dubbelt
sidband 435020.

Nu finns en ny version av SatPC32. Läs nedan!

SatPC32 Version 12.8b Available

AMSAT News Service Bulletin 296.07
From AMSAT HQ SILVER SPRING, MD.
October 23, 2011
To All RADIO AMATEURS
BID: $ANS-296.07

SatPC32 version 12.8b is available for download at
http://www.dk1tb.de/downloadeng.htm

The main SatPC32 program window now displays more information such as
the date of the Keplerian elements file in use.

Before upgrading your SatPC32 installation, be sure to use the new
program (in the ZIP file) to backup your user configuration.  The
upgrade erases all previous user configurations, but the new program
will restore your configurations after upgrading.

The download is a demo version that requires users to enter their
lat/lon each time the program is started.  To make the program fully
functional, enter your existing registration code or purchase a
registration code from the AMSAT web site:
http://www.amsat-na.com/store/category.php?c=Software

DK1TB, the author of SatPC32 has donated the software to AMSAT.  All
sales of SatPC32 are used to support AMSAT.

Here are the changes described in the What’s New file:

1. SatPC32, SatPC32ISS, Wisat32 and SuM now support rotor control of the
M2 RC-2800 rotor system.

2. The CAT control functions of SatPC32, SatPC32ISS and Wisat32 have
been expanded. The programs now provide CAT control of the new Icom
transceiver IC-9100.

3. The main windows of SatPC32 and SatPC32ISS have been slightly changed
to make them clearer. With window size W3 the world map can be stretched
(only SatPC32).

4. The accuracy of the rotor positions can now be adjusted for the
particular rotor controller. SatPC32 therefore can output the rotor
positions with 0, 1 or 2 decimals. Corrections of the antenna positions
can automatically be saved. In previous versions that had to be done
manually.

5. The tool ‘DataBackup’ has been added. The tool allows users to save
the SatPC32 program data via mouse click and to restore them if
necessary. After the program has been configured for the user’s
equipment the settings should be saved with ‘DataBackup’. If problems
occur later, the program can easily restore the working configuration.

6. The rotor interfaces IF-100, FODTrack, RifPC and KCT require the
kerneldriver IOPort.SYS to be installed. Since it is a 32-bit driver it
will not work on 64-bit Windows systems. On such systems the driver can
cause error messages.To prevent such messages the driver can now
optionally be deactivated.

7. SuM now outputs a DDE string with azimuth and elevation, that can be
evaluated by client programs. Some demo files show how to program and
configure the client.

AubieSat-1 Launch Includes Four Additional Satellites

AMSAT News Service Bulletin 296.05
From AMSAT HQ SILVER SPRING, MD.
October 23, 2011
To All RADIO AMATEURS
BID: $ANS-296.05

The launch of Auburn University’s AubieSat-1 satellite has been rescheduled to
28 October 2011 due to problems found during the system integration of the
primary mission. A hydraulic system leak was detected and the cause was found to
be a small crack in a hydraulic tube. A replacement tube was manufactured,
installed, and retested. Also, a flexible fabric collar connecting two engine
system exhaust ducts was found to be damaged following pressurized leak testing.
The damaged
fabric collar is being removed and replaced.

Home

AubieSat-1 is designed to transmit with a power of about 800 milliwatts on a
frequency of 437.475 MHz, plus or minus Doppler correction. The beacon signal,
along with telemetry, will be sent using A1A continuous wave Morse code at 20
words per minute. Additional telemetry from the on board science experiment will
use CW transmissions up to 60 WPM.

An internet Echolink conference group is also planned to begin one-half hour
prior to launch and continue until about 30 minutes after confirmation of the
first receipt of signals from the satellite. Information on the conference
groups title will be distributed nearer to the launch for interested stations.

Auburn’s famous battle cry, “War Eagle,” will be heard from space October 28
when it is transmitted to earth from a student-built satellite known as
“AubieSat-1.” Auburn University’s web page includes a video about their mission:

Radiomjukvaran SDR-Radio stödjer nu även USB-radio FUNCube Dongle med bla. trackingmöjligheter för satelliter. Hela nyheten här:

BID: $ANS-247.05

AMSAT-UK’s FUNcube is an educational single cubesat project with the
goal of enthusing and educating young people about radio, space, phy-
sics and electronics. FUNcube will carry a UHF to VHF linear transpon-
der that will have up to 1 watt and which can be used by Radio Ama-
teurs worldwide for SSB and CW communications. Measuring just
10 x 10 x 10 cm, and with a mass of less than 1kg, it will be the
smallest ever satellite to carry a linear transponder

It will support the educational Science, Technology, Engineering and
Math (STEM) initiatives and provide an additional resource for the
GB4FUN Mobile Communications Centre.

The target audience consists of primary and secondary school pupils
and FUNcube will feature a 145 MHz telemetry beacon that will provide
a strong signal for the pupils to receive.

A simple SDR receiver board (FUNcube Dongle) has been developed to
support this mission by providing a simple radio interface to the
classroom. The FUNcube Dongle connects to the USB port of a laptop
to display telemetry and messages in an interesting way for students.

But, even before FUNcube has been launched amateur satellite operators
have discovered that the 64 MHz to 1,700 MHz coverage of this Software
Defined Radio receiver can be used for most amateur, along with some
weather and commercial satellite reception.

This week, Simon Brown, GD4ELI/HB9DRV, announced he has enhanced his
popular SDR-RADIO software to provide support for the AMSAT-UK FUNcube
dongle software defined radio. The SDR-RADIO.com software has been up-
graded to provide full support for the FUNcube dongle including satel-
lite tracking, Doppler compensation and data for external rotator
software via DDE. This free software can be downloaded from
http://www.sdr-radio.com/
