145.825 MHz APRS Cubesats Enroute to ISS for August Deployment

The June 29, 2018 SpaceX Falcon 9 launch of the Dragon cargo
capsule included cubesats of the BIRDS-2 satellite constellation.
All cubesats in the BIRDS-2 constellation MAYA-1, BHUTAN-1 and
UiTMSAT-1 have identical designs and utilize the same radio
frequencies. While independently made, the operation and control
of the three cubesats will be shared by the three teams after
they are released from the ISS early in August. They will be
operational for six months.

"The three will form a constellation, orbiting the earth from
different places. This will provide the countries more opportun-
ities to make measurements and run experiments, than just with
using one cubesat," explained Joel Joseph Marciano Jr., manager
of the PHL-Microsat program in the Philippines.

The primary mission of BIRDS-2 CubeSat constellation is to
provide digital message relay service to the amateur radio
community by means of an APRS digipeater onboard. The APRS
digipeater onboard BIRDS-2 CubeSats will use 145.825 MHz for
both receive and transmit which isa standard configurations
used by other satellites such as ARISS and LAPAN-A2.

Another mission of the BIRDS-2 CubeSat constellation is to
demonstrate a store-and-forward (S&F) system. In this mission,
their goal is to investigate technical challenges through ex-
periments on appropriate data format, multiple access scheme,
file-handling protocol while complying with limited operational
time and power constraints.

The BIRDS-2 CubeSat S&F system will collect data from remote
ground sensors, store them onboard and download them to the
different BIRDS-2 ground stations network.

Additional experiments will use the BIRDS-2 CubeSat constellation
to enhance research and experiment in the fields of single latch-up
event detection, magnetic field measurements using a COTS aniso-
tropic magnetometer, and flight testing of a COTS GPS chip which
can be used for future CubeSat missions if proven effective. Stu-
dents will also explore a passive attitude stabilization mechanism
consisting of magnets and hysteresis dampers for proper orientation
of camera on a CubeSat. All measurements and image data will be
shared with the public on BIRDS-2 project website.

Moveover, BIRDS-2 CubeSat constellation will expand amateur radio
communication experiment on the operation of CubeSat constellation
via a network of UHF/VHF amateur radio ground stations (started
in the BIRDS-1 CubeSat constellation project). BIRDS-2 hopes to
promote awareness of amateur radio communication and amateur
satellites among the general public and students, especially in
the participating nations of BIRDS-2 Project: Bhutan, Malaysia,
Philippines, and Japan.

The IARU has coordinated 437.375 MHz CW beacon for a downlink and
145.825 MHz for the APRS experiment.

"Moon Day" Volunteers Requested

Tom Schuessler, N5HYP, is looking to recruit additional volunteers
from the AMSAT community in North Texas, Central Texas or elsewhere,
to help promote "Amateur Radio in Space" to a large public STEM
event.  "Moon Day" at the Frontiers of Flight Museum at Love Field in
Dallas Texas on July 21, 2018 is the largest space themed STEM event
in Texas.  Last year saw 1500 people attend the 6 hour event.
https://www.flightmuseum.com/moon-day/

Again this year, Tom Schuessler will be heading an exhibit and
satellite demos for AMSAT.  They will have a table inside the Museum,
(Alongside the Dallas Amateur Radio Club Table), and a demonstration
area outside.  I will be setting up the outside activities and hope
to work as many satellite passes as possible during the 10A-4P run of
the show.

I'm looking for AMSAT people to both help with the inside table and
also with the outside demonstrations.  Joe Spier has promised me that
he will send me the FOX "Engineering Model"  but I am looking for
additional demonstration aids to illustrate satellite orbits and
other aspects of space communications like various types of antennas.

Being a STEM event, there will be many young people in attendance,
(General public as well as Boy and Girl Scouts), and they get a
chance to earn a STEM patch by answering questions from exhibitors
like US.

We really need people and content for Moon Day so please consider
spending Saturday, July 21 with us.  Contact Tom Schuessler for more
information.  N5hyp (at) arrl.net

Tom also notes that next year, 2019, is the 50th anniversary of the
Apollo 11 moon landing. The Moon Day event is planning a big splash.
Looking at moon phase predictions for next year indicates that
conditions would be favorable for a portable EME station as part of
the mix. We will be looking for volunteers to assist this lofty goal.

Keep that in the back of your mind and I will bring it up next year.

University of Manitoba Wins the 4th CSDC!

Congratulations to the University of Manitoba team, which earned
First Place in this fourth offering of the Canadian Satellite Design
Challenge! The CSDC launch simulation testing took place at the
Canadian Space Agency's David Florida Laboratory (DFL) in Ottawa this
past week, concluding yesterday. In all, a total of nine teams had
the opportunity to fully test all three axes of their cubesats - two
more than previously achieved.

As the competition drew to a close, the judges (and several of the
DFL employees) were impressed by the level of design maturity and
understanding, preparedness, and professionalism of the UofM team
throughout the test campaign. This is the first CSDC win for the
UofM, which has been a strong and enthusiastic participant in every
CSDC since its inception. Not everything went perfectly, however: an
accelerometer - a sensor which is attached to record the
accelerations at a particular location - fell off during the
vibration test, and may have shorted or damaged a circuit board that
was underneath it.

The judges' deliberations for second and third place were far more
difficult, with five teams being considered. This is a testament to
the high level of spacecraft engineering capability which has
developed at Canadian universities over the course of these past four
competitions - especially considering that, in the first CSDC, only
three teams were able to complete their cubesats in time for testing.
Second place honours were given to the University of Victoria, and
Concordia University was third.

The Educational Outreach Award was also presented, to the University
of Alberta. Their team developed several modules of age-specific
educational materials for the presentations which they gave to
elementary and secondary schools. Honourable mentions went to: Simon
Fraser University (participating for their first time in the CSDC)
for their efforts which reached an estimated 3,500 people over the
course of this offering; and, the University of Manitoba, whose
educational outreach efforts have been admirable since the inception
of the CSDC (and whose Educational Outreach efforts in the first CSDC
prompted the creation of the award).

The CSDC Management Society (CSCDMS), the not-for-profit
organisation which organises the CSDC, would like to again thank the
Canadian Space Agency's David Florida Laboratory for allowing us the
use of the facility, and for being so accommodating to us over this
past week. Additionally, as this concludes the fourth offering of the
competition, the CSDCMS would also like to thank the many sponsors,
judges, and companies which have all contributed to make the CSDC a
success. Please see this article on our web page for more photos of
the testing campaign.

And, stay tuned for Selfie-Sat in CSDC-5, which will begin in
September.

The Canadian Satellite Design Challenge Management Society is a
federally-incorporated not-for-profit organisation co-registered in
British Columbia and headquartered in Vancouver. It is managed and

ISS SSTV Transmissions Continue

SSTV transmissions from the Russian Service module on the
International Space Station started June 29 on 145.800 MHz FM and
they are still continuing

There may well be further transmissions up until July 13 when the
equipment being used for the SSTV will be required for a school
contact.

David Boult G7HCE in Exeter noted that some adjustments have been
made by the cosmonauts and the images are now being sent uncropped.
For the first week the edges of the pictures were missing.

The images commemorate the various satellites that were hand-
deployed from the ISS. These will include the first satellite
deployment from ISS: Suitsat-1/Radioskaf-1 which was developed by
ARISS and deployed in February 2006.

The transmissions are being made on 145.800 MHz FM using the PD-120
SSTV mode.

Note the ISS transmissions use the 5 kHz deviation FM standard
rather than the narrow 2.5 kHz used in Europe. If your transceiver
has selectable FM filters try using the wider filter. Handheld
transceivers generally have a single wide filter fitted as standard
and you should get good results outdoors using just a 1/4 wave whip
antenna.

The ISS Fan Club site will show you when the space station is in
range http://www.issfanclub.com/

Since we are not supposed to be using SSB, CW, or digital modes on the FM

I've decided to part with my home station and go back to being a fully
portable operator for the foreseeable future. So here's what I got:

145mhz Innovantenna 5 Element X-Pol
435mhz Innovantenna 10 Element X-Pol (Factory New, just unboxed,
inventoried and repackaged).
2x Innovantenna 2m Balun
2x Innovantenna 70cm Balun
2x Comet 4160N Dupelxers
2x C2G N-Male to N-Male Barrel Connector
2x Tohtsu CX520D Relays, with Dissapation Capacitor Installed.
2x 12 Gauge Wires to Relays with Soldered Ends
4x Andrew CNT-400 Short Jumpers (2' to 4') with Amphenol N-Male Connectors
for between Baluns and Relays.
2x DXE Basic Saddle Clamps for Mounting Box
1x DXE Heavy Duty Saddle Clamp for 145mhz X-Pol boom.

$550 + Shipping (Guessing it will be about $75 anywhere in the lower 48,
will get an exact quote if

A few notes - the 145mhz X-Pol was outside for about 10 months at my QTH
(Just long enough for me to get my 488 finished) as was an old 435mhz beam,
but I damaged part of the 435mhz during disassembly, therefore I ordered
replacement 435 metal and it is all factory new never exposed to the
weather. All the relays and duplexers were inside weatherproof housings on
the Mast and all in good working order. I also drilled holes for a heavy
duty DXE saddle clamp on the 2m boom because I had some trouble with the
factory saddle clamp slipping on my fiberglass cross beam. There's no
slipping now.

Here's a picture of everything all spread out on the shop floor:

At this time I'm not interested in any trades, and I'm not interested in
splitting what I have listed up. Shipping on this is gonna be kinda pricey
so if you're anywhere within about 500 miles or so of EM34 I'm willing to
meet halfway. Any questions or serious inquiries email me at

I will be doing a satellite talk and demo this coming Wednesday evening,
July 11th, for the Euless Texas Amateur Radio Club.  The pass for the demo
will be XW-2A at 8:21 CDT which is 0121Z 12-July.  A good east coast pass
but not so good for the Rockies and west.  The demo will be somewhat
ambitious for me, with RX on a FunCube Dongle Pro+ run by HDSDR and
controlled by SatPC32.  The uplink radio will by my FT847.  We will use the
Euless club call W5EUL for any contacts.  Might be the first time that their
club call has been used on satellite, I don't know.  Please look for me
probably near the center of the passband and give us a shout.

Well, it is a well known that in some universes a double negative results in
a positive result. I'm interested in taking an attempt at imaging OSCAR
satellites. Any tips from the community for say, AO-7, using an optical
telescope and a DSLR mounted at its focus?

With any luck, AO-7 will outlive (or perhaps it already has) the IBM punch
card that caused the whole 5-digit thing in the first place.  Of the
constants in the universe, the first one is 42, immediately followed by
either 72 or 80, depending on your background.  We apparently had
programmers define the KEPs format, as both lines are 71 characters long... :)

(For source code, columns 73-80 were reserved for sequence numbers, so that
when you dropped your deck, the cards could be reassembled in the proper
order.)

Samudra,

You might ask the folks at seesat-l
http://www.satobs.org/seesat/seesatindex.html

It seems to me that I saw paper on viewing the early OSCARs. Either in an
early newsletter or Symposium proceeding. If I can find it I?ll post it.
