The O/OREOS satellite is NASA's first cubesat

O/OREOS (Organism/ORganics Exposure to Orbital Stresses) Nanosatellite


The O/OREOS satellite is NASA's first cubesat to demonstrate the capability to have two distinct, completely independent science experiments on an autonomous satellite. One experiment will test how microorganisms survive and adapt to the stresses of space; the other will monitor the stability of organic molecules in space.

TRACK THE FASTTRAC SATELLITE Nov 19th 2010

Dear members of the University Nanosat, Cubesat, and Amateur Radio
communities,

As many of you may know, the FASTRAC satellites built by students at
UT-Austin will be launched as part of the STP-S26 mission this upcoming
Friday Nov 19th (around 4:30 pm AST) from Kodiak, Alaska on board a Minotaur
IV rocket. The satellites will be placed into a 650 km altitude, 72 degree
inclination circular orbit. For those that don't know, the FASTRAC
satellites are the winners of the University Nanosat-3 Competiton and their
primary mission is to demonstrate enabling technologies for small
satellites.

The satellites have been designed the satellites so that amateur radio
operators can track them all over the world and to do so the team has built
a section on our website (
http://fastrac.ae.utexas.edu/for_radio_operators/overview.php) that allows
any amateur radio operator to upload data they receive from the satellites.
This serves two purposes which are that the website will parse and
graphically interpret the data received and also allows the team to collect
data from all over the world.

With this in mind we would like to invite you to track our satellites and
register on our website. All of the information to track the satellites is
available on the above website where we will be posting the most up to date
TLEs as they become available as well as any other pertinent information.
Also, we will be posting updates as the launch approaches on our website,
our Facebook page (www.facebook.com/fastracsats) and our Twitter page (
www.twitter.com/fastracsats) so make sure to chek them out.

Thank you for your help. 73,

Glenn Lightsey (KE5DDG) and Sebasti?n Mu?oz (KE5FKV)
FASTRAC Principal Investigator and FASTRAC Student Program Manager

HO-68 v AO-51 ??.

From: John Hackett wrote at EU-AMSAT mail list
To: eu-amsat@yahoogroups.com
Sent: Sun, Apr 25, 2010 3:50 pm
Subject: [eu-amsat] HO-68 versus AO-51
HO-68 v AO-51 ??.
HO-68 versus AO-51 - and the university downlink only satellites - (aka the FM
menagerie).In my honest opinion it's a 'no contest' scenario - with HO-68 winning hands down.
The two main reasons for me making this claim are ...
1) HO-68's superior orbit.
2) It's multi-mode transponders.
On a typical European pass an HO-68 orbit has a footprint the covers from Spain
in the west to India in the east, Norway in the north to Sudan in the south ...
and all points in between.
Whereas AO-51 is FM only ... HO-68 has transponders for CW, SSB as well as FM.
HO-68 is (IMHO) easier to operate due to it needing less power to get into the
transponders, albeit, to really take advantage of that, a knowledge of CW is
required, which *STILL* shows it's great advantage as weak signal mode.
When all else fails ... switch to CW.
Igor, RW3XL has been operating cross-satellite with HO-68 to VO-52 and HO-68 to
AO-7 ... keying the up down buttons for CW since his keyer is on the blink.
For those wanting to learn, the 200mW beacon sends *SLOW* morse and it's
copyable on a piece of wet string wrapped round a rusty six inch nail.
I've proved this over and over on HO-68 at the beginning of passes when the
elevation is under 20 degrees and a SSB just can't make it - switch to CW - Q5
copy - (Domenico, I8CVS will endorse that).
I believe that HO-68 is becoming the experienced 'operator's' satellite while
AO-51 will remain the platform for the potential newcomer ... where they can
QRM eachother to their heart's content ... more power Egon ... MORE POWER !!!
... (with due apologies to the Hollywood film 'Frankenstein').
For me at least, HO-68 has brought the fun back into amateur satellite
operating, particularly on CW ... akin to RS-10, the most popular satellite
ever - (judged by the amount of users) - after the veritable old AO-7.
While everyone is entitled to his or her opinion, operating FM on a satellite
is about as much fun for me as watching paint dry and is, in my opinion, the
worst possible way to introduce a potential newcomer to amateur satellites. My
EU-Amsat co-founder, SV1BSX
(SK) first used the word 'zoo' to describe the AO-51 standard of operating.
There ought to be a sign on the microphone ... PLEASE DON'T FEED THE ANIMALS.

In the next HO-68 schedule 11-18 April 3 passes preserve for SSTV mode on FM transponder!
This is a good chance to encouraging swl and scanner fans to receive some sstv pictures.
may this recruit more young people to satellite.

I’ve tested my setup on SO-50 21:10 UTC with a fair result , but not like HO-68

WiSP hints #4 test TNC -RIG -PC keying line

After hardware wiring of the TNC Rig with the PC
do the following to test the Keying line.

GSC--> Tracking--> Run pass --> select satellite --> OK

MSPE window wll pop up ,If every thing is ok you wll notice the TNC
LEDs blink three time = TNC in KISS Mode.

If there is an error message check again the ports and TNC setup .

On MSPE click fill --> small window pop up for different requests.

Chose fill directory --> and click ok your rig suppose to transmit
a frame of packet.

Now Use other radio and listen to confirm the transmission is ok.

Wisp Hints #3 - Fast upload

Hints to make Wisp more faster to upload messages to satellite
especially for HO-68 satellite.

1st - Prepare fresh messages and delete any none uploaded messages.

2nd- Do not make Wisp busy by requesting Dir or reading a file.
on the other hand DO NOT make the satellite busy too.

( DO NOTHING ) Let Wisp Hear the satellite .
Wisp w'll do every thing automatically to upload your files.

This is very important step (advice) and I'll say it again !!
(DO NOTHING ) Just watch your screen and enjoy your hot tea
and let Wisp hear and talk with the satellite alone.

3rd-The above advice wll prevent collision of the packet data between
your station and satellite .So more faster handshake of data in less time.

4th-Prepare your message with short title.

5th- Write your message in shorthand style .

6th- No need for HUGE signatures .See below the cool Alan's post at AMSAT 28 Jun 2000

All,
I've noticed that there are some *huge* signatures on messages posted to the
sats. I'm all for telling people who you are and what you do. But I saw
one that had to be over 20 lines. It was more than the message. Isn't that
kinda wasted bandwidth? If there wasn't email or qrz.com, maybe I could see
it, but I'd think it would be better to place that stuff on a web page and
not *every* message.

More wisp hints #2 - Update keps

It was an old problem in Wisp to update the satellite database easy!

My solution
1- Deleting the old wisp keps file.
2- Update only the keps for the satellite you want to use.eg AO-51,GO-32,HO-68
No need for the other sats at database file.
3- Prepate the keps for the satellites you want to use in a Notepad text file.
4- Re-update database .




More Wisp hints

1- Do File Housekeeping and Directory maintenance.
2- Delete any partial upload file ! I notice HO-68 refuse / deny the existence of any partial upload file on its BBS.
3- Use the faster PC you have.
4-IMHO - XP is the best OS for Wisp!
5-Many friends asked me about Wisp's setup -see photos pse

6 messages uploaded & more Wisp info

I succeeded to uploaded 6 messages today (20-03-2010)
to Hope-1 BBS.

My plan was to upload 13 messages!!
Yes I did the math and many tests for this acording to satellite pass.

Unfortunately the FM ruin my all week plan!! (For sure an unintended QRM ).

Anyhow the following photos show more info
about Wisp and the amount of data it can handling
according to pass time etc.


Tnx dk3wn for download hope-1 Dir






It works! thank you guys

Where my pul file # 161 gone? And where my uploaded file # 160

At HO-68 Orbit #1205 Wisp started to upload a file number 161
The file 161 partial uploaded .on the next pass orbit # 1206 wisp try to upload what left from the file but the sever on satellite denied existance of file # 161 !!
and shift to upload the next file #162 (see 2nd photo)

Again the Directory was empty ??? I uploaded 2 or 3 messages yesterday and 1 messages
today file # 160 . As you can see in the photo #2 .The satellite
was accepted the file.

I requested the directory as my friend Mike DK3WN did !but it was empty! see this on the 3rd photo . where the Multipsk on other PC monitoring the Hope-1 satellite downlink by soundcard.

This question I 've asked several time !
is there something wrong on HO-68 BBS??

Again some stations FMing and QRMing the Digi Week !!!
