Hello all,
Got all your TESTING UPLOAD messages in loud and clear. My message to
K4KDR didn't get send out. I'm still (re)searching about the cause of
this. Later......

Subject: [amsat-bb] Upcoming ARISS contact with Rowan Preparatory
School, Claygate, United Kingdom
Message-ID: <F006754895A7450892AFC1D8681C89DF@???>
Content-Type: text/plain; charset="iso-8859-1"
An International Space Station school contact has been planned with
participants at Rowan Preparatory School, Claygate, United Kingdom on 20
June. The event is scheduled to begin at approximately 12:48 UTC. The
duration of the contact is approximately 9 minutes and 30 seconds. The
contact will be direct between NA1SS and GB4RPS. The contact should be
audible over the United Kingdom and adjacent areas. Interested parties are
invited to listen in on the 145.80 MHz downlink. The contact is expected to
be conducted in English.
Story:
Rowan Preparatory School is a vibrant, friendly and nurturing community
where girls are encouraged to be themselves. Our school is an independent
preparatory school for girls between the ages of 2 to 11, located in the
heart of Claygate (near Esher) in Surrey. A school with traditional values
and a forward thinking approach to education, we seek to offer a broad and
adventurous curriculum full of exciting opportunities.
School life at Rowan is inspiring and offers a breadth of experiences which
develop the whole child. The warmth that is evident when you walk through
the door at Rowan creates the ideal learning environment for girls to fulfil
their potential. They are nurtured and allowed to grow as individuals,
encouraged to take risks and have a go at new skills and interests which
will enrich their lives. Science, Technology, Engineering and Maths are at
the heart of the curriculum at Rowan. Girls make the most of our dedicated
specialist teaching spaces and delight in practical learning opportunities
in the Engineering and Technology suite. From 3D printers to our radio
recording studio, the environment at Rowan is geared towards encouraging
creative and exciting learning, ensuring that the girls explore, question
and discover in every area of learning. We are passionate about bringing
STEM subjects to life and encouraging the girls to see how these subjects
translate into the world beyond schoo
l. Experiences which will foster successful and inspirational women of the
future!
Rowan girls are prepared for the transition to a wide range of successful
day and boarding schools and we pride ourselves on finding the right senior
school environment for each and every girl. A personalised approach to
learning and outstanding pastoral care in our happy environment, ensures
that every girl develops a genuine love of learning.
Participants will ask as many of the following questions as time allows:
1. How did the International Space Station get built when it just
balances in the air?
2. What are the challenges to growing food in space if astronauts are
to stay in space for longer?
3. Does your digestion change because in space there is no gravity so
your intestine will float in your body?
4. Of all the experiments that you have done in space, what has given
the most surprising result or has been the most exciting?
5. If you spin a ball in the ISS will it keep spinning or will it stop,
and if it stops, what stops it?
6. In the future, will it be possible that someone can spend their
entire life in space and if so, would their life expectancy change?
7. If you do a handstand in space does your blood go to your head if
there is no gravity?
8. Is there anything you could learn about how bacteria and viruses
behave in space that could help us defeat infectious bugs around the
Earth?
9. NASA have said that they will establish a permanent presence on the
moon within the next decade, how will they do this and what is the
most exciting benefit for human kind?
10. In all of your time spent on board the ISS, what is the most
exciting and extraordinary thing that you have experienced?
11. What new information about space are you hoping to learn?
12. Can you escape from a black hole?
13. We have learnt that astronauts are very busy and work long hours.
So when you have free time, what do you do for fun?
14. How do you get rid of rubbish in space?
15. What are you looking forward to the most in nature when you return?
16. Our teachers and parents tell us that having a balanced diet is
important. Is your diet closely monitored or do you have freedom to
choose what you eat? What is your favourite meal?
17. How do you sleep in space?
18. What kind of dangers might you experience in space?
19. What is the most beautiful thing you can see in space?
20. We have heard that some people don't believe that the Moon landing
took place, what is the best evidence that we have to disprove this
theory?

About ARISS
Amateur Radio on the International Space Station (ARISS) is a cooperative
venture of international amateur radio societies and the space agencies that
support the International Space Station (ISS). In the United States,
sponsors are the Radio Amateur Satellite Corporation (AMSAT), the American
Radio Relay League (ARRL), the ISS National Lab and National Aeronautics and
Space Administration (NASA). The primary goal of ARISS is to promote
exploration of science, technology, engineering, and mathematics (STEM)
topics by organizing scheduled contacts via amateur radio between crew
members aboard the ISS and students in classrooms or public forms. Before
and during these radio contacts, students, educators, parents, and
communities learn about space, space technologies, and amateur radio. For

Content-Type: text/plain; charset=windows-1252; format=flowed
Okay, many hours googling and reading later......... I came upon two
documents with some relevant information. First this is from the
document "Pacsat File Header Definition". As it already says, it give a
definition:
-------BEGIN-------
3.1.9 body_checksum
id????????????? :??? 0x09
length????????? :??? 2
data??????????? :??? unsigned int body_checksum
A 16 bit checksum formed by adding all bytes in the file body into a 16
bit variable, ignoring overflow.? The <body_checksum> does not include
the bytes comprising the PACSAT file header.
The <body_checksum> is primarily intended to detect mis-corrected
multi-bit errors caused by Single Event Upsets in the PACSAT memory.
INITIALIZATION - The correct <body_checksum> must be supplied.
-------END-------
I don't quite understand the second but last sentence: does the PACSAT
memory get upset by my messages?
From "Pacsat Protocol: File Transfer Level 0" document more on the
upload procedures:
-------BEGIN-------
7.4. Completion of Upload
7.4.1 Successful Upload Completion
When the server receives the DATA_END packet it will check the integrity
of the file as far as possible.? If the checks pass, the server will
downlink a
UL_ACK_RESP packet.
Packet: UL_ACK_RESP
Information: none
After transmitting the UL_ACK_RESP the server uplink state variable is
UL_CMD_OK.? After receiving the UL_ACK_RESP, the client uplink state
variable is UL_CMD_OK.
7.4.2 Failure Caused by Server Rejecting Upload
The server may reject an upload while the client is sending DATA packets
(due to file system problems on the server) or after the client has sent
the DATA_END packet (due to corruption of the file).
If the server must abort the upload while receiving DATA packets or
after receiving the DATA_END checks fail, it sends the UL_NAK_RESP packet.
Information: 1 byte
???? unsigned char err_code;
<err_code>???? must be one of:
ER_BAD_HEADER - The file either has no PFH, or has a badly-formed PFH.
ER_HEADER_CHECK - The PFH checksum failed.
ER_BODY_CHECK - The PFH body checksum failed.
ER_NO_ROOM - The server ran out of room for file storage before the
upload was complete. The server will implement procedures to avoid
frequently running out of room, but this cannot be guaranteed.
After transmitting the UL_NAK_RESP packet, the server uplink state
variable is UL_CMD_OK.? After receiving the UL_ERROR_RESP, the client
uplink state variable is UL_CMD_OK.
-------END-------
So I clearly get a UL_NAK_RESP packet with the ER_BODY_CHECK error.
I also downloaded the PACSAT Ground Station software source code from
G0KLA (hello Chris). The hex code for the BODY_CHECKSUM is 0x09. If you
search for that in the source code you come up with the file Crc16.java.
My coding skills are very minimal, so I don't grok the code completely,
but I do see something strange in that file Crc16.java:
-------BEGIN-------
String s = "HELLO";
???? byte[] bytes = s.getBytes();
???? //Crc16 crc = new Crc16(bytes);
???? short cs = 0;
???? for(byte b : bytes)
???? ??? cs += b & 0xff;
???? System.out.println(cs);
???? PacSatField pf = new PacSatField(cs, 0x09);
???? System.out.println(pf);
??? }
-------END-------
String s is probed for the number of bytes, then "converted" into
variable cs, which is the PacSatField 0x09, iow the Body_Checksum. Now
string s is simply "HELLO" and I don't see if this is hard coded or that
this string changes according to the content of the message body. Any
Java programmers here who want to help me look at it?
Any help appreciated. Cheers,

Some months ago someone told me about an app that I think was created by a
UK ham. It is a great color timeline showing visual indications of when
satellites rise and decline and their elevations for any location as set in
the setup screen. The timeline also shows the time for each satellite rise
based on the users location. Users can also decide which which satellites
they want to include on the timeline. Various parameters like these are
established in the setup screen.
I?m now at my vacation QTH and for the life of me I can?t remember the name
of this app and want to install it on my computer at the lake house. Can
someone point me in the right direction.

Hi folks,
I have been off from the satellite for a while due to the broken Funcube
Dongle Pro Plus.
I have ordered and received a coupe of days ago my new one but I cannot get
it working
Properly on the Falconsat-3 Bird.
I explain the problem hoping in some help.
I am using SDRSharp - HW Virtual Serial Port - UZ7HO's High Speed Soundmodem
- Wisp
When I receive the satellite I can see the data incoming in the UZ7HO's High
Speed Soundmodem
But I do not see nothing in the MSPE ( Wisp ).
When I try to transmit I can see the radio going in TX and it remains in TX
as locked and get the error form the
UZ7HO's High Speed Soundmodem saying:
Error opening wave output device (unspecified error).
I cannot get in RX again so I need to reset the PC.
Please anybody can explain me were am I doing wrong?
Thanks
