A
Hello,
everybody:
this
is
Michelle
w5nyv,
here's
a
link
to
my
resume.
If
you
want
to
see
my
professional
credentials
I'm
here
today
to
share
a
presentation
with
you,
this
is
a
proposal
for
a
work
in
progress
for
an
open
source,
Communications
satellite,
it's
a
heo
or
highly
elliptical
orbit,
but
most
of
this
work
applies
to
Geo
as
well.
High
orbit,
satellites
from
heo
to
Geo
are
of
great
interest
to
all
of
us.
A
Open,
Research
Institute,
where
I
spend
a
lot
of
volunteer
time,
has
been
very
successful
in
laying
down
the
regulatory
groundwork
to
allow
International
collaboration,
open
source
and
open
process
amateur
satellite
work.
This
is
regulatory
relief
that
we
did
not
have
before.
There
are
two
parts
to
this
regulatory
work:
first
itar
and
ear
regulatory
relief
with
an
advisory
opinion
on
publishing
on
the
internet.
You
can
see
a
poster
session
about
that
work
here
at
ham,
Expo,
second
debris
mitigation
and
orbit
talks
with
the
FCC.
A
A
Second,
that
the
FCC
understands
the
orbits
that
amateurs
are
interested
in.
There
are
two
that
Ori
discussed
with
the
FCC
first
straight
to
graveyard,
which
puts
a
geospace
craft
into
disposal
orbit
directly.
The
mission
plan
must
be
done
completely
and
carefully
and
there
is
no
automatic
approval
of
a
license,
but
the
FCC
understands
what
the
community
wants
and
has
no
objection
to
pursuing
designs
that
use
straight
to
graveyard.
This
is
very
good
news.
A
This
has
advantages
and
disadvantages
which
we'll
be
talking
about.
This
work
was
completed
in
November
of
2021..
You
can
find
it
in
the
MVP
folder
in
our
regulatory
repository.
Mvp
stands
for
minimum
viable
product.
The
paper
discusses
an
amateur-centric
approach
to
communication
satellites,
given
debris
mitigation
rules.
These
efforts
took
a
lot
of
time.
A
Thank
you
to
everyone
that
was
involved
in
these
regulatory
successes.
The
regulatory
work
sets
the
stage
for
the
technical
work.
This
current
effort
is
based
on
a
proposal
from
Jan
king
and
a
team
of
volunteers
that
helped
him.
It
was
presented
in
2014
to
amsat
n.
A
amsat
did
not
follow
up
on
it
and
there
is
a
story
about
why.
But
it's
not
my
story
to
tell
The
Proposal
surfaced
a
number
of
times
in
the
open
source.
Amateur
radio
scene,
I
put
it
out
to
the
Ori
mailing
list
for
discussion
and
potential
adoption.
A
The
timing
could
not
have
been
worse
because
it
was
the
week
that
covid-19
started
shutting
down
things
in
the
U.S
back
in
2020.
in
the
summer
of
2022,
Makia
Murray
of
jamsat
suggested
that
I
try
and
find
something
to
propose
to
jam
set
for
heo
and
I
immediately
thought
of
this
proposal.
I
asked
Jan
King
how
he
felt
about
updating
it.
He
was
all
for
it,
so
we
started
working
on
it
and
building
a
team.
We've
had
three
work
sessions
all
recorded
and
published
for
anyone
to
watch.
A
We
walked
through
the
proposal
and
identified
the
areas
that
needed
to
be
changed.
A
lot
has
happened
in
the
years
since
the
proposal
was
put
together,
but
it
was
excellently
done
and
the
basics
have
stood
the
test
of
time.
This
is
a
fully
open
source
project
that
is
open
to
any
participant
almost
anywhere.
A
The
team
is
already
International.
Jam
Set
members
have
given
invaluable
guidance
for
the
updated
design.
Our
goal
is
to
produce
the
highest
quality
proposal
possible.
Libra,
Space
Foundation
is
in
the
loop,
and
their
membership
has
been
supportive
and
helpful.
All
amsat
members
are
invited
to
participate
and
several
have
signed
on.
There
is
a
pledge
of
fifty
thousand
dollars
from
an
individual
donor.
If
the
proposal
is
accepted,
if
you
can
match
this
or
want
to
contribute
financially,
then
get
in
touch
all
versions
of
all
the
slides
are
available
in
our
Repository
we'll.
A
We
will
be
going
quickly
over
some
of
the
slides
today
in
order
to
focus
on
the
areas
of
greatest
progress
and
where
we
need
the
most
help.
This
is
a
team
effort.
It's
a
great
privilege
to
be
able
to
present
the
work
of
so
many
people.
Ori
has
a
very
flat
organizational
structure
which
lets
projects
be
projects
and
doesn't
put
a
lot
of
impediments
between
the
people
and
the
planning.
Ori
has
clearly
defined
participant
and
developer
policies,
a
code
of
conduct
and
a
culture
of
keeping
the
focus
on
the
project.
A
A
So,
let's
get
to
the
proposal,
items
in
red
are
action
items
they
are
actively
under
revision.
First,
we
have
the
mission
objectives
in
2014.
Communications
was
still
considered
to
be
experimental.
We
have
changed
that
to
clearly
state
that
the
mission
objective
is
to
deploy
a
functional
Communications
resource.
The
original
proposal
had
10
gigahertz
and
24
gigahertz
as
the
amateur
communication
frequencies.
A
A
Thank
you
to
the
several
microwave
Societies
in
the
US
and
in
Europe
that
have
already
provided
feedback
comment
and
critique
about
multi-band
transponder
possibilities.
So
a
full
transponder
would
have
one
two.
Five,
ten
and
24
gigahertz
bands
represented
note
the
0.5
meter
disk
requirement.
This
is
from
jamsat.
Japanese
operators
have
limited
space
to
work
with.
This
is
a
change
from
the
original
proposal
and
it
does
affect
the
link
budget.
A
This
Mission
demonstrates
open
source
design
work
and
there
is
an
opportunity
for
small
scientific
payloads.
We
will
not
select
or
propose
experiments,
but,
as
you
will
see
in
the
system
block
diagram,
there
will
be
interfaces
for
experiments.
We
defer
the
choice
of
experimental
payloads
to
whoever
accepts
The
Proposal.
There
are
so
many
good
ideas
for
experiments
and
other
organizations
will
have
informed
opinions
that
we
will
want
to
support
and
connections
with
experimenters
that
we
simply
do
not
have.
A
We
want
to
provide
the
widest
opportunities
for
science,
technology,
art
and
culture
in
space
mission
objectives
continue
with
specific,
open
source
propulsion
goals.
We
will
show
the
ability
of
electric
propulsion
to
carry
out
critical
Mission
functions,
while
not
interfering
with
high-speed
digital
Communications.
A
Finally,
this
is
something
that
we
Center
in
our
work.
We
will
promote
International,
Goodwill
and
amateur
technical
education
through
open
source
design
and
development.
We
do
not
believe
in
opaque
or
authoritarian
methodologies.
We
believe
that
amateur
radio
should
be
inclusive
and
supportive,
and
that
gatekeeping
is
for
trolls.
Heo
missions
have
a
past.
Here
are
four
missions
that
a
lot
of
you
may
be
very
familiar
with.
Some
of
these
were
International
and
collaborative
it's
past
time
to
go
back
to
space
like
this.
Our
community
is
fully
capable
of
doing
this.
A
The
challenges
and
resources
and
formats
are
different
now,
but
we
are
up
to
the
challenges.
We
have
the
resources
and
we
have
mastered
the
formats.
The
next
thing
the
proposal
addresses
is
orbits.
We
will
have
a
japanese-centric
orbit
along
with
a
North
American
one
and
however
many
more
we
need.
The
big
change
from
the
original
proposal
is
raising
the
altitude
from
500
kilometers
to
1250
kilometers,
to
avoid
crossing
over
the
orbital
shells
of
the
commercial
constellations
at
low
earth
orbit.
A
This
change
comes
from
what
we
learned
during
the
regulatory
work
with
the
United
States
Federal
Communications
Commission.
There
are
at
least
two
drawbacks
to
raising
the
altitude
like
this
first
desaturation
of
the
reaction.
Wheels
is
harder
if
you
don't
go
down
to
something
like
500
kilometers,
so
this
is
something
that
we
need
to
quantify.
Second,
preliminary
analysis
shows
that
the
Delta
V
is
higher.
A
We
have
a
result
from
an
amsat
DL
volunteer
that
it's
three
times
higher
at
1250
than
500.,
so
we
will
be
using
GMAT
or
the
general
Mission
analysis
tool
from
NASA
to
specify
the
orbits
and
to
produce
the
values
needed.
This
is
an
open
source
software.
It's
high
resolution
and
widely
used
the
U.S
fcc's
encouraging
spacecraft
to
deorbit.
As
soon
as
the
mission
is
completed,
this
modified
orbit
May
consume
more
fuel
than
the
original
proposed
orbit.
These
two
facts
are
not
necessarily
in
Conflict.
A
A
goal
of
Ori
work
is
to
get
faster
turnover
in
space
for
amateur
missions,
so
that
we
can
build
up
a
larger
Archive
of
proven
designs
instead
of
having
one
egg
and
one
basket
at
a
time
to
be
very
clear,
the
FCC
no
longer
really
wants
25-year
plans.
They
want
missions
that
work
hard
for
less
time
and
then
get
out
of
the
way.
Five
to
seven
years
is
the
goal
for
this
payload,
with
10
years
being
a
true
stretch
goal.
A
The
payload
is
at
least
a
6u
spacecraft
or
six
units.
This
is
the
2014
physical
configuration.
There
are
some
things
that
will
change,
such
as
the
solar
panel
deployment
style
and
there
will
be
a
lot
of
Sensor,
Fusion
and
less
mass,
and
we
will
move
things
around
to
where
the
engines
are
not
right
by
the
antennas.
A
The
spacecraft
internal
volume
allocation
is
most
likely
going
to
change,
but
you
can
see
the
thinking
from
2014
here.
We
really
want
to
get
the
engines
as
far
away
from
the
antennas
as
we
can,
because
even
with
the
synchronization
work
that
we're
going
to
include
still
needs
to
be
far
the
further
away.
A
A
It
has
a
dedicated
RF
link
and
there
are
at
least
two
RF
Communications
boards.
Here
we
show
a
five
gigahertz
Uplink
and
a
10
gigahertz
downlink
subsystem.
Note
the
RF
switches
here.
This
is
something
that
we
want
to
prototype
right
away,
these
switches
flip
if
the
digital
board
dies
or
they
can
be
flipped
on
command.
The
entire
thing
is
converted
from
a
fancy
digital
regenerative
repeater
system
into
a
straightforward.
What
goes
in
is
what
comes
out
type
of
transponder
okay.
So
why
would
we
do
this?
A
Well,
we
want
the
communications
resource
to
work
regardless
of
the
digital
brains.
It
will
negatively
impact
the
link
budget
and
you
will
lose
some
functions
like
authentication
and
authorization,
but
you
get
something
that
can
fail
over
instead
of
just
fail.
This
is
important
to
us
because
we
are
pragmatic
about
Communications.
A
If
you
want
to
be
part
of
building
this
prototype,
get
in
touch
assumptions
about
cubesat,
Power
Systems
have
changed.
This
proposal
will
have
a
simplified,
28
volt
subsystem,
solar
arrays
will
not
be
hinged
the
same
way.
They
were
for
the
original
proposal,
we're
looking
at
foldouts
on
the
long
Edge.
The
mass
budget
will
change.
Assumptions
about
mass
per
unit
are
now
lower
attitude.
Control
Baseline
is
Reaction
Wheel
with
off-the-shelf
components.
A
A
A
A
Access
to
the
transponder
was
listed
as
contention
based,
but
we
have
a
better
scheme
with
authentication
and
authorization
that
work
is
being
presented
this
weekend
by
another
Ori
volunteer.
So
please
check
out
the
schedule.
Also,
all
presentations
will
be
on
our
YouTube
account
after
the
ham
Expo
platform
closes
about
a
month
from
now.
A
Quick
note
here
is
a
diagram
describing
the
token
generation.
This
is
a
brief
snapshot
of
the
Innovative
work
going
into
the
Uplink
protocol.
The
forward
error
correction
on
the
downlink
and
the
Uplink
has
been
updated.
The
downlink
is
bch
plus
ldpc
from
dvbs2
and
S2X,
and
the
Uplink
uses
opulent
voice
with
convolutional
and
golay
encoding.
A
High
bitrate
Opus
codecs
are
used
in
the
native
digital
uplink.
16
kilobits
per
second
is
what
we're
testing
with,
but
Opus
can
go
up
to
500
kilobits
per
second,
you
will
have
excellent
voice
quality
using
our
Uplink
and
data
can
be
transmitted
without
having
to
switch
to
a
clunky
packet
mode.
This
work
is
being
developed
for
terrestrial
use
as
well.
If
you
are
interested
in
helping
make
an
open
source,
microban
HT
with
excellent
voice
quality,
then
there's
a
team
working
on
this
and
you
are
welcome
to
join.
We
deserve
excellent
voice.
A
You
can
access
the
development
stations
over
the
internet.
All
of
the
development
Hardware
is
in
ori's
remote
Labs,
there's
a
full
vivato
license
and
a
full
Matlab
license
with
all
the
toolboxes.
You
saw
a
deep
dive
presentation
on
the
downlink
encoder
about
six
months
ago.
At
the
March
2022
ham,
Expo
presented
by
Andre
suato.
A
We
will
need
more
people
to
help
with
integrating
the
reference
design
on
flight
Hardware.
So
if
this
sounds
exciting
to
you,
then
welcome
aboard.
We
also
have
an
ultrascale
Dev
board
up
and
running
for
the
Next
Generation
past.
What
we're
talking
about
here,
if
you
want
to
help
get
polar
codes
on
the
air
for
deep
space
missions,
we
have
your
back
power.
Amplifier
notes
are
here
this
or
a
similar
part
is
going
to
be
the
Baseline
I'm
going
to
skip
over
the
link
budgets
for
now.
For
two
reasons.
A
First,
we
have
an
excellent
link
budget
spreadsheet
from
Jan
King,
which
has
been
recently
renovated
and
expanded
for
our
purposes,
and
we
already
know
that
enough
has
changed
from
when
these
budgets
were
done,
that
they're
no
longer
accurate
and
I'm
going
to
make
an
editorial
note
here
about
link
budgets.
They
are
aware
items
if
you're
not
familiar
with
the
link
budget,
then
here's
the
20.
a
link
budget
is
very
similar
to
a
financial
budget.
You
have
power
that
you
can
spend
and
that
power
must
create
a
signal
that
the
receiver
can
hear.
A
You
have
degrees
of
freedom
that
you
can
use
to
create
more
gain
in
the
transmitter.
What
that
transmitter
throws
up
must
be
able
to
be
received
by
the
receiver,
so
it
is
like
balancing
your
checkbook,
but
the
thing
that
most
people
miss
about
link
budgets
is
that
actual
Hardware
in
real
environments
are
pretty
ugly
and
messy.
Many
link
budgets
are
just
too
simple.
Therefore
they
are
too
conservative.
Some
link
budgets.
Arguably,
the
massive
Excel
spreadsheet
from
Jan
King
are
too
complex
for
casual
use.
A
If
you
don't
know
the
right
answers
to
all
the
values
in
the
spreadsheet
and
for
Jan's
work,
there
are
a
lot
of
values.
Then
you
can
end
up
with
an
answer.
That's
wildly
wrong.
Link
budgets
are
truly
accurate.
Only
when
the
system
is
complete
and
you
can
measure
everything,
backfill
the
link
budget
and
go
look
at
that.
It
worked.
A
So
at
this
stage
we
do
have
link
budgets
that
show
we're
in
the
ballpark
that
we
can
close
the
link
and
that's
good
enough
to
put
our
backs
into
this
and
get
it
done.
We
will
be
using
Jan
King's,
extremely
Advanced
Link
budget
along
the
way,
but
it
will
be
for
documentation
as
much
or
more
than
as
a
predictive
tool.
A
We
have
the
answer.
We
can
close
the
link
it's
up
to
us
to
get
every
last
tenth
of
a
DB
out
of
the
link,
because
any
increase
is
an
increase
in
throughput.
This
is
how
real
systems
tend
to
be
built.
The
link
budget
is
an
extremely
valuable
tool
to
get
the
most
out
of
the
design
and
we're
past
the
first
hurdle
here.
A
A
Here's
more
about
ttnc
there's
link
budgets
for
the
Telemetry
tracking
and
command
as
well.
Rad
FX
was
proposed
for
this
payload,
but,
as
explained
earlier
for
this
proposal,
we
are
providing
an
interface
for
experiments,
but
not
specifying
them.
Imagine
if
we're
at
FX
could
have
flown
on
this
heo
if
it
had
been
accepted
by
amsat
in
a
pretty
cool
proposal.
A
The
one
experiment
we
can
do
inherently
is
a
precipitation
attenuation
study
and
I'm
really
excited
about
this.
Here's
the
original
proposal,
which
involves
a
beacon.
However,
with
adaptive
coding
and
modulation
in
the
downlight
protocol,
we
may
be
able
to
report
results
simply
by
letting
the
protocol
adapt
to
the
channel
record
what
it
does
and
cross-reference
this
with
meteorological
data.
There
is
a
big
opportunity
here
for
Sensor
Fusion,
computer
vision
and
machine
learning.
This
is
essentially
ambient
science,
because
the
communication
signals
themselves
provide
valuable
weather-related
data.
A
This
makes
transmitting
on
24
gigahertz
much
more
interesting
as
it
allows
us
to
see
whether
with
our
transponder,
how
cool
is
that
here's
the
original
design
for
the
attenuation
experiment?
We
think
we
can
simplify
this
and
also
extract
more
data
than
originally
envisioned.
Now
we
come
to
the
electric
propulsion
subsystem.
A
Ori
has
the
green
light
to
develop
an
open
source
application
of
US
patent
number
one:
zero,
zero,
zero,
six,
four,
four
five!
This
is
a
wonderful
opportunity
and
we
are
going
to
take
full
advantage
of
it.
This
vacuum,
Arc,
Thruster
micro
propulsion
subsystem,
is
an
outgrowth
of
the
gwu
micro
propulsion
and
nanotechnology.

A
The
engine
will
do
two
things:
it'll
raise
the
orbit
and
assist
in
disposal.
A
key
part
of
this
patent
is
synchronization
of
the

which

Electric

create
a

of

We
have
a
fundraiser
going
on
right
now
to
build
engineering
models
and
to
retest.
The
design
here
are
some
very
early
photos
of
the
engine,
and
here
is
historical

of
the

You
need
to
define
the
frequency
that
you're
going
to
be
working
on
so
I'm,
going
to
click.
One
okay
great
go

because
I
want
one

and
that
actually
set
it

know,

Basically,
that's
fine,
we'll
we'll
translate
that

and
initiate
the
pulse
by
pressing
the
number

button.
I'm
gonna
go
to

on

yeah
click

There
we
go
and
we
can

The
original
proposal
had
a
total
integrated
dose
experiment.
This
is
a
very
low
volume
experiment.
We
are,
we
are
concerned
about
radiation,
so
we
will
very
likely
keep
it.
Here
is
a
view
of
the
expected
interfaces.
The
double
lines
indicate
redundancy.
There
is
both
a
hardware
and
software
heartbeat
between
the
SDR
board
and
the
ttnc.
This
allows
for
different
recovery
modes.
A
A
Here
is
a
walkthrough
of
some
of
the
system,
architecture,
reasoning
and
decisions.
Here's
what's
been
reviewed.
There
is
a
system
architecture
document
in
the
repository,
and
these
are
the
slides
that
go
with
that
work.
So,
first
we
have
the
system
block
diagram,
here's
some
detailed
call
outs,
highlighting
critical
Parts
note.
We
have
Splitters
and
bandpass
filters
here.
The
Splitters
work
in
concert
with
the
switches
in
order
to
implement
our
failover
mode.
There
will
be
losses
and
complexity
associated
with
the
extra
parts
required
to
pull
this
off.
A
If
the
digital
board
fails,
the
switches
activate
and
signals
are
routed
around
the
digital
board.
Here's
a
very
high
level
estimate
of
the
riskiest
parts
of
the
design,
some
similar
designs
that
can
be
used
as
resources
or
references.
This
is
the
hardware
states
which
are
defined
as
the
RF
switch
States.
We
have
four
modes:
there's
a
transponder
mode,
digital
mode,
transponder,
plus
UHF
Telemetry
and
digital
mode,
plus
UHF
telemetry.
A
Our
SDR
has
pre-loaded
files,
so
it
can
operate
as
a
beacon
so
that
people
can
test
their
stations.
The
idea
here
is
to
roll,
through
all
the
modulation
and
coding
combinations
in
dbbs2
S2X,
so
that
the
station
capability
can
be
measured.
The
default
digital
download
content
will
play
when
there
is
no
traffic.
You
can
see
an
example
of
this
working
as
our
terrestrial
multimedia
Beacon
project.
We
have
a
playlist
for
this
part
of
the
project
on
ori's
YouTube
account.
A
Here
is
a
description
and
context
for
some
of
the
requirements
for
interfaces.
We
think
of
the
ttnc
system
as
an
intelligent
router,
and
we
know
that
the
ttnc
bus
needs
to
be
multi-master
hot
swappable
and
low
power.
There's
a
finite
State
machine
involved
with
the
collection
of
the
Telemetry,
the
heartbeat
monitoring
and
fault
recovery
are
also
managed
with
the
state
machine.
Here's
the
definition
of
the
fault,
detection,
isolation
and
Recovery.
There's
three
sets
of
undesired
effects
and
specific
mitigation
strategies.
We
aim
for
graceful
degradation
and
not
the
elimination
of
all
faults.
A
The
most
frequently
asked
about
extension
is
a
camera.
There
are
two
options
and
they
are
enumerated
here
with
their
advantages
and
disadvantages.
We
can
put
a
camera
on
the
digital
board
and
have
it
interface
to
the
SDR
fpga
or
the
camera
can
have
its
own
ttnc
bus
interface.
What
other
resources
do
we
have?

will
come
out
of
it.
What
do
we
not
have?
Well,
we
don't
have
an
experienced
thermal
design
person
and
we
don't
have
a
lot
of
mechanical
engineers
on
staff.

the
greatest
needs.
What
happens
next?
Well,
we
push
hard
to
complete
this
proposal
to
the
best
of
our
ability.
All
this
