AO-85 Update: Do Not Access While in Eclipse
The auto Safe mode was disabled on June 24 and the transponder was
turned on. A few QSOs were made to verify that it would drop with
inactivity.
Currently, the battery voltage is very low and it looks like a cell
is prepared to give up the ghost. Please do not use the satellite
while it is in eclipse, even if you hear it. Operations is not sure
what will be usable if and when this cell fails completely.
In the meantime, please send reports to the AMSAT-BB. THey are
welcome and helpful.

PSAT Successfully Launched on Falcon Heavy STP-2
PSAT2 was successfully Launched at 0630Z on June 25, 2019 on the
Falcon Heavy STP-2 mission into a 28 degree elliptical orbit with
apogee at 860 km and perigee at 300 km. The 28 degree inclination
makes it difficult to work it over most of Europe but the
significant difference in apogee and perigee can make a 15 degree or
so elevation difference on the horizon. When apogee circulates to
be over the northern hemisphere,then more northern stations can
work it. When Perigee is over the
northern hemisphere, it can only be seen in Spain and Italy latitudes
in Europe, and only mid latitudes in the USA.
This changing apogee dynamic will move earlier each day and two weeks
later, will have reversed, and so forth on a monthly cycle or so.
Another interesting thing about the orbit is that it is almost time
synchronous; meaning that a pass will occur almost the same time
every day (though five minutes earlier). But then an earlier orbit
will appear an hour and a half earlier every other day. This makes
it very easy to do mobile/portable operations without any computer
once you hear one pass.
Operating Modes
PSAT2 consists of a number of exciting and unique Amateur Radio
Communications transponders:
- First is a newer PSK31 29 MHz uplink/UHF FM downlink from Brno
University following on to the original on PSAT.
- Second is a Brno SSTV camera that dowlinks in the same UHF FM
waterfall as the PSK31 users.
- Third is a DTMF grid square uplink and voice/APRS downlink for
grid position reporting.
- Fourth is DTMF Text messaging (APRStt).
- Fifth is APRS text messages up and voice down.
- Sixth is a conventional APRS digipeater that will join a number of
sister APRS Amateur Satellite transponders.
Currently the HF/UHF PSK31 and SSTV modes are enabled and open to
users.
But the VHF modes have not been enabled for users and users are
requested
to keep the uplink clear during on-orbit testing.
PSAT2 is designed for maximum orbit life compared to other similar
sized
cubesats because it is flying with the maxzimum allowable mass.
Almost a
kilogram of lead ballast about 2cm x 8cm x 8cm located in the center
of
the cubesat constitutes almost HALF the satellite's mass to give it
a high
ballistic coefficient to last longer on orbit.
One of the most interesting and unique features of PSAT2 is the new
APRStt (Touchtone) DTMF/voice transponder which lets everyone do APRS
using any radio with DTMF keypad, not just those with APRS radios.
There have been several iterations of the APRStt system in APRS over
the years since 2001, but this application will be new in space and
will help introduce everyone to this unique alternate APRS
capability for use with ANY radio.
Operating Frequencies
- APRS Up/Down: 145.825 1200 baud APRS (like ISS, PSAT, AISAT-1)
- DTMF Uplink: 145.980 MHz (Voice confirmation down on 145.825 MHz)
- PSK31 Downlink: 435.350 MHz +/- 5 kHz FM (300 mw)
- PSK31 Uplink: 29.4815 MHz PSK31 SSB (25 W and omni vertical
typical)
PSAT2 Digipeater Aliases
To join the existing APRS satellites on orbit and operate as a
seamless constellation, PSAT2 supports the same APRSAT and ARISS
generic aliases as the original PCSAT (NO44) PSAT and the packet
system on the ISS so that users do not have to change any
parameters when using any of these three APRS transponders.
Complete PSAT-2 information is available at:
http://aprs.org/psat2.html
The PSAT2 User Manual is available for download at:
aprs.org/PSAT2/USER-Operations-Manual.doc
[ANS thanks Bob Bruninga, WB4APR for the above information.]
--------------------------------------------------------------------
Update: PSAT2 is coming to Northern Latitudes!
After reviewing the orbit, it is somewhat time synchronous, meaning
each orbit time (at mid northern latitudes) is just 5 minutes later
each night. But then a NEW earlier orbit appears 90 minutes earlier
every other day.
So, by the 4th of July, PSAT2 first pass will be as early as 4 PM
local time in the Northern Hemisphere mid latitudes.
And, the apogee moves rapidly. In just two weeks, apogee will be
over the northern hemisphere giving higher latitudes much better
access. At launch it was the middle of the night and perigee was in
the Northern hemisphere making it only visible for lower latitudes.
So, things will improve for Northern Hemisphere... then two weeks
get worse, etc.
24 Hour telemetry plots (links to FINDU.COM) are now available on at
http://aprs.org/psat2.html.

Chinese Lunar Satellite DSLWP-B and the July 2 Solar Eclipse
On July 2 there will be a total solar eclipse that can be observed
from parts of the Pacific Ocean, Chile and Argentina. This provides
an opportunity to image the eclipse with the Chinese lunar orbiting
Amateur Radio satellite Lunar-OSCAR 94 (aka DSLWP-B). An attempt
will be made to image the eclipse with the Inory eye camera on-
board, where both the Moon and Earth should appear in the images.
The main interest is to photograph the shadow of the Moon on the
surface of the Earth. The camera doesnt have a large resolution and
the Earth will look small in the image, but it will be possible to
distinguish the shadow clearly.
Because the satellite aims its solar panel towards the sun, the
camera on-board DSLWP-B is always pointing away from the Sun.
Since DSLWP-B orbits the Moon, the Earth will always be in the center
of the camera field of view during a solar eclipse. However, it
might happen that the Moon is between the satellite and the Earth
thus hiding the view of the Earth.

ARISS International Delegates Meet in Montreal
This week, ARISS held it's 2019 ARISS International Face-to Face
Meeting of international delegates in Montreal, Canada. During the
sessions, Kenwood software manager, Shin Aota presented two Kenwood
TM-D710GA transceivers to ARISS Russia delegate Sergey Samburov. A
TM-D710GA will be used to replace aging amateur radio equipment on
board the International Space Station.
For several weeks, these radios have undergone detailed qualification
testing followed by software configuration and verification. With
today's transfer of the radios to ARISS Russia, we are one step
closer to an enhanced Amateur Radio system on board the ISS
supporting various operations such as SSTV, voice communication,
APRS and a variety of experiments.

European Astro Pi Challenge Winners Announced
Two Raspberry Pi computers, Astro Pi units Ed and Izzy have called
the International Space Station home since 2016. ESA Education runs
the European Astro Pi Challenge which allows students to conduct
scientific investigations in space, by writing computer programs.
A record-breaking number of more than 15000 people, from all 22 ESA
Member States as well as Canada, Slovenia, and Malta, took part in
this years challenge across both Mission Space Lab and Mission Zero.
After designing their own scientific investigations and having their
programs run aboard the International Space Station, the Mission
Space Lab teams spent their time analysing the data they received
back from the ISS. To complete the challenge, they had to write a
short scientific report discussing their results and highlighting
the conclusions of their experiments. We were very impressed by the
quality of the reports, which showed a high level of scientific merit.
the Astro Pi jury has now selected eleven winning teams, as well as
highly commending four additional teams. The eleven winning teams
won the chance to join an exclusive video call with ESA astronaut
Frank De Winne, head of the European Astronaut Centre in Germany
where astronauts train for their missions. Each team had the once-in-
a-lifetime chance to ask Frank about his life as an astronaut.

New Release of G0KLA Tracker
Chris Thompson, G0KLA/AC2CZ has released version 1.01a of the G0KLA
Satellite tracker. This version has a few tweaks most requested by
users:
- Key display settings can be changed on the main window from a set
of icons bottom left. e.g. showing spacecraft in eclipse vs sun.
- Horizontal lines for 30 and 60 degrees can be displayed.
- Horizontal lines for all labels on the vertical axis can be
displayed.
- Time labels have a slightly more sensible gap between them
(e.g. 15 minutes) rather than a random amount that fit in the
window (such as 13 minutes).
- Past minutes can now be as short as 10 minutes, although a
longer period can be selected.

works at http://aprs.org/MobileLEOtracking.html.
Bob adds, "It's easy to remember. Five minutes later per day, but a
new orbit an hour and a half earlier every other day. This is
approximate but time will tell.
"If you are in the wilderness, just monitor 145.825 and when you hear
PSAT2, then you can easily guess all orbits in the future."
