From YouTube: Open Research Institute About Us and Beacon Demo
Description
Presentation about ORI with a Multimedia DVB-S2 Beacon Demo.
A
Open
research
institute
or
ori
is
a
non-profit
research
and
development
organization,
which
provides
all
of
its
work
to
the
general
public
under
the
principles
of
open
source
and
open
access
to
research.
These
mean
particular
things.
Open
source
is
a
type
of
intellectual
property
management,
where
everything
you
need
to
recreate
or
modify
a
design
is
freely
available.
A
All
we
do
is
open
source
work
primarily
for
amateur
radio,
space
and
terrestrial,
but
also
some
other
fields,
as
you
will
see.
So
who
are
we
well?
Here's
our
current
board
of
directors
of
five
and
our
immediate
past,
ceo
bruce
parents.
We
have
several
other,
very
wonderful
advisors
and
we
thank
them
all.
The
time
we
are
experienced
in
management,
engineering
operations
and
technology
and
three
out
of
five
are
from
underrepresented
groups
in
stem
as
a
board.
It
is
our
mission
to
serve
our
participants,
developers
and
community
members.
A
A
We
have
some
affiliations
and
we
ascribe
to
the
open
space
manifesto
from
libra
space
foundation.
We
work
with
several
radio
clubs
several
universities
and
have
worked
with
a
variety
of
for
profits.
What
do
we
do?
Here's
a
visual
summary
of
top
level
projects
and
initiatives.
The
vertical
axis
is
risk.
Higher
risk
projects
are
at
the
top
lower
risk
projects
are
at
the
bottom.
Maturity
increases
from
left
to
right.
A
A
The
color
of
the
shape
indicates
how
much
stress
that
project
is
under
or
what
the
risk
level
is
at
this
time
the
size
of
the
shape
is
the
budget
estimate
by
far
the
largest
budget
and
the
riskiest
and
the
least
mature
work
is
in
the
aquaphage
project,
which
is
an
open
source.
Bacteriophage
research
and
development
bacteriophage
are
viruses
that
attack
and
destroy
bacteria.
A
This
is
a
biomedical
and
not
an
amateur
radio
project.
This
project
was
halted
by
covid
and
has
not
yet
resumed
our
digital
multiplexing
payload
project
is
called
p4dx
and
it's
in
the
middle
in
green.
This
is
a
multiple
access,
microwave
digital,
regenerating
repeater
for
space
and
terrestrial
development.
A
The
m17
project
is
an
open
source,
vhf
uhf
radio
protocol
think
open
source,
digital
mode,
hts
and
repeaters.
This
project
is
only
slightly
more
stressed
than
p40x,
but
it's
further
along
in
maturity,
because
it's
narrower
in
scope.
We
believe
the
m17
project
will
be
very
successful
from
current
development
to
scaling
up
to
commercial
product
launch.
The
m17
protocol
is
the
native
digital
uplink
protocol,
with
some
modifications
for
five
gigahertz
for
p40x
engineers
general.
Is
our
initiative
to
hire
highly
competent,
open
source
workers
to
reduce
burnout
and
increase
quality
and
open
source
work?
A
A
The
bird
bath
is
a
large
dish
antenna
at
the
huntsville
space
and
rocket
center.
This
dish
was
used
in
the
past
for
demonstrations
in
amateur
activity,
but
it
has
been
parked
for
decades.
It
took
two
years
of
negotiation,
but
ori
has
the
support
of
the
museum
and
permission
to
begin
work.
Renovating
this
dish
for
citizen
science
and
amateur
radio,
educational
use
work.
Parties
from
earlier
this
year
were
rescheduled
due
to
covid.
The
first
one
will
be
in
december
of
2021
upper
right.
There
are
two
completed
projects.
A
A
This
is
a
huge
step
forward
for
not
just
amateur
radio,
but
anyone
that
wants
to
contribute
to
open
source
space
work,
debris
mitigation,
regulatory
work
took
10
months
to
complete
the
process,
culminated
in
a
highly
successful
meeting
with
the
fcc
wireless
telecommunications
board,
the
office
of
engineering
technology
and
the
satellite
bureau.
This
past
thursday,
our
first
orbit
workshop
based
on
this
work
was
earlier
today.
A
A
Ambisat
inspired,
sensors
used
to
be
on
the
bottom
right,
but
now
it's
bumped
back
a
bit
at
maturity,
level
and
more
stressed
and
higher
risk.
This
was
supposed
to
be
a
project
done
by
students
at
vanderbilt
university,
but
no
students
have
materialized
primarily
due
to
covid.
We
have
one
kickbutt
professional
volunteer
who
is
working
on
a
10,
gigahertz
beacon
sensor
that
fits
into
the
sensor
connector
on
the
main
board,
but
we
wanted
to
spin
the
main
board
to
move
it
from
the
illegal
ism
band.
It
was
on
to
the
legal
70
centimeter
handband
for
space.
A
A
All
of
these
projects
are
open
source
and
all
work
is
published
as
it's
created
when
well.
We
have
timelines,
we
were
incorporated
in
february
of
2018,
got
our
501c3
in
march
to
2019,
and
we
hit
the
ground
running
and
haven't
stopped
since
we'll
distribute
a
copy
of
the
slides.
So
you
can
see
our
wins
and
losses
along
the
way,
there's
a
lot
packed
in
here,
any
one
of
which
could
probably
be
a
full
presentation.
A
A
Note
the
second
item
and
put
in
the
word
hardware
instead
of
software
and
that's
one
of
the
reasons
we
demonstrate
early
and
often
and
incorporate
the
feedback
quickly,
so
we
might
be
agile
with
a
little
bit
of
lean,
but
we
also
work
in
some
traditional
waterfall
management
techniques
as
well.
Here's
the
swot
foursquare
for
p40x,
these
four
grids
quite
often
interact.
Opportunities
are
often
ringed
by
threats
and
threats
can
reveal
opportunities.
A
Weaknesses
can
be
compensated
by
developing
overlooked
strengths
and
so
on.
We've
weathered
several
major
threats
and
things
keep
progressing
for
an
amateur
radio
project
like
p40x.
There
are
a
lot
of
amateur
radio
specific
challenges
such
as
the
regulatory
environment,
which
we
have
changed
for
the
better
and
a
variety
of
threats
from
other
organizations
with
radically
different
agendas.
A
Where
are
we
here's
the
locations
of
the
concentrations
of
current
major
contributors
and
participants?
So
when
we
say
international,
we
mean
it,
our
participants
have
a
wide
range
of
ages
are
generally
educated
generally
in
engineering,
come
from
a
variety
of
backgrounds,
but
do
tend
to
be
relatively
young
and
male.
A
A
A
A
A
As
you
have
seen,
one
of
our
projects
is
a
multiple
access
broadband
digital
system
at
microwave
that
is
designed
to
be
used
in
very
high
altitude
payloads
in
space
or
terrestrially
channels
divided
in
frequency
of
the
uplink.
The
uplink
is
on
five
gigahertz,
the
processor
on
the
payload,
digitizes
and
multiplexes
these
signals
and
uses
dvb,
s2
and
s2x
as
a
single
time
division
downlink
the
downlink
is
on
10
gigahertz.
A
The
system
adapts
to
channel
conditions
and
handles
things
like
quality
of
service
decisions,
for
example,
low
and
high
latency
digital
content.
The
uplink
is
divided
up
using
a
polyphase
channelizer,
which
opens
the
possibility
of
reconfiguring
uplink
channels
in
orbit
or
in
the
field,
while
most
amateur
television
systems
use
the
mpeg
transport
stream.
We
replace
this
with
another
dvb
protocol
called
generic
stream
encapsulation,
so
that
any
type
of
data
is
efficiently
transmitted.
A
The
end-to-end
system
is
coming
together
in
an
fpga-based
design
that
can
then
become
a
custom.
Asic
part
of
the
system
is
a
default
digital
downlink
when
there
is
no
or
light
traffic,
we
want
to
place
signals
that
run
through
all
the
combinations
of
modulations
and
forward
error,
correction
coding.
So
that
people
can
fully
test
the
receivers,
this
payload
function
is
essentially
a
beacon,
so
we
are
making
a
small
number
of
them.
This
is
an
early
prototype
and
it
will
go
up
in
southern
california
as
quickly
as
possible.
A
When
we
say
broadband,
we
mean
on
the
order
of
10
megahertz,
the
symbol
rate
is
fixed
and
the
modulation
and
error
correction
coding
vary
to
allow
different
capability
stations
experiencing
different
channel
conditions
to
close
the
loop.
This
is
called
adaptive,
coding
and
modulation
for
this
prototype.
We
are
only
using
an
impact
transport
stream,
but
generic
data
is
the
goal.
The
beacon
signal
is
five
megahertz
wide
and
we
are
using
one
modulation
and
one
error
coding
so
far.
We
are
not
yet
rotating
through
all
the
allowed
combinations
in
dbb,
s2
and
s2x.
A
B
B
B
B
So
all
we
got
to
do
is
generate
the
signal
in
the
box
in
the
computer,
create
the
rf
of
the
signal
here
in
the
blade,
rf
and
then
up,
convert
it
to
10
gigahertz,
that's
very
similar
to
how
an
actual
implementation
of
this
beacon
will
work.
Although
none
of
these
boxes
are
probably
going
to
appear
in
a
real
deployable
implementation.
B
B
B
It
comes
out
at
uhf,
around
600
and
something
megahertz,
and
that
goes
through
this
piece
of
coaxial
cable.
To
this
little
shiny
silver
box,
which
is
a
mini
tuner
express
this
box
was
manufactured
for
ham,
radio,
use
for
digital
amateur
television
and
they're
quite
inexpensive.
They
were
only
about
75
dollars,
unfortunately,
they're
no
longer
available,
but
a
replacement
product
is
in
the
pipeline
right
now
and
hopefully
will
also
be
quite
affordable
and
it's
connected
by
usb
to
a
windows
laptop.
B
B
You
can
see
here
in
this
box
that
it's
searching
across
a
range
of
frequencies
trying
to
find
the
signal
at
the
frequency
that
it's
looking
at,
which
is
not
the
right
frequency
either,
and
here
it's
got
an
estimate
of
noise
and
all
sorts
of
interesting
data.
This
picture
down
here
is
especially
interesting.
This
is,
what's
called
a
constellation
diagram.
B
B
B
We
picked
a
frequency
off
the
the
band
plan
for
10
gigahertz.
There's
no
entry
in
the
band
plan
for
broadband
beacons,
but
there
is
an
area
in
the
band
plan.
That's
for
broadband,
so
we
chose
one
of
those
frequencies
and
maybe
you
have
to
choose
a
different
one
before
we're
done,
but
that's
the
one
we're
using
right
now,
so
one
zero,
ten
gigahertz,
three,
seven,
seven:
five:
zero,
zero
kilohertz
so
just
above
the
weak
signal
area
of
the
band.
B
B
B
B
B
The
signal
comes
over
here
to
the
inner
layer
and
a
modulator,
which
is
where
the
actual
modulation
takes
place.
It's
set.
You
may
be
able
to
read
it.
It
says:
16,
a
psk
and
9
10.,
so
it's
a
constellation
of
possible
signals
being
used,
there's
16
of
them.
They
vary
in
both
amplitude
and
phase.
So
it's
amplitude
and
phase
shift
keying
with
16
possibilities
and
the
code
rate
is
9
10,
which
is
pretty
fast,
so
relatively
minimal
error.
Correction
capability
still
quite
good,
but
not
a
lot
of
overhead.
B
The
signal
goes
over
here
to
the
physical
layer
framer,
which
arranges
it
in
such
a
way
that
it
can
actually
be
transmitted
and
then
there's
a
final
filter
to
take
all
the
nasty
edges
off,
and
this
signal
goes
two
places.
It
goes
to
this
block,
which
creates
a
visualization
of
the
signal
which
we'll
see
here
in
a
second
and
this
block,
which
interfaces
with
the
the
sdr
hardware-
the
blade
rf
in
this
case.
B
So
all
I
have
to
do
to
run
this
program.
Is
click
go
so
clicking,
go
we'll
see
some
stuff
scroll
by
as
it
initializes
and
then
the
the
frequency
sync
visualizer
pops
up
and
it
shows
a
nice
square
signal.
This
is
what
all
high
performance
digital
signals
look
like
kind
of
flat
on
the
top
with
steep
sides.
B
B
B
It
needs
about
14,
so
we've
got
about
8
db
of
margin,
which
is
what
this
d8
here
means,
and
the
decoder
is
happy
all
green
and
lo
and
behold,
there's
video
and
audio
this
block.
This
set
this
pie
chart
here
shows
how
the
bits
are
being
utilized
with
5
000
kilo,
samples
per
second
and
16
aps
k,
modulation
and
a
rate
nine
tenths
code.
B
B
B
If
I
hit
another
key
I'll
bring
the
video
up
to
full
screen,
that
is
a
very
pretty
picture.
Now
this
this
is
black
and
white,
but
that's
not
a
limitation
of
the
demo.
It's
just
the
file
it's
actually
being
transmitted
in
full
color.
It
happens
that
this
particular
music
video
is
all
black
and
white,
because
the
footage
is
old.
Mostly,
that
is
not
the
kind
of
picture
you
expect
to
see
on
amateur
television
using
analog
means,
in
fact,
that's
that's
quite
impressive.
In
my
book.
That's
a
very
nice
picture.
B
There
are
other
features
that
is
programming,
don't
need
to
go
through
them
all.
Just
the
fact
that
we're
able
to
send
this
many
bits
reliably
over
microwave
is
what
the
demo
is
about
now.
The
interesting
thing,
well,
one
limitation
that
we're
of
this
demo
that
I'm
showing
you
right
now
is
that
the
video
is
pre-canned.
B
I'm
going
to
switch
to
a
slightly
different
flow
graph.
This
flow
graph
is
almost
identical,
but
it
it
gets
the
video
from
a
named
pipe
instead
of
from
a
file-
and
I
come
over
to
this
window
and
I
renamed
a
script
that
generates
the
video
to
the
named
pipe,
and
this
video
is
coming
from
the
webcam.
This
webcam
here
on
top
of
the
screen,
so
that's
now
generating
the
video
all
I
have
to
do
is
come
over
here
and
run
the
flow
graph
once
again,
we'll
see
pretty
much
the
same
sort
of
display.
B
The
spectrum
looks
the
same,
regardless
of
what
you're
transmitting
really
that's
a
feature,
and
over
here
you
can
see
the
video
being
generated
frame
by
frame
and
if
we
go
back
over
to
the
receiver,
you'll
see
that
it's
back
on
again,
the
carrier
lock
is,
is
full
smash,
and
so
is
the
symbol
right
lock
and
our
power
is
out.
We've
got
8
db
of
margin
or
9
depending
and
the
constellation
diagram
is
very
pretty
it'll.
Take
a
few
seconds
to
actually
lock
onto
the
video.
B
B
B
B
B
Here
we
go,
it
just
came
back.
I
don't
know
what
the
issue
is
with
that,
but
interesting,
there's,
never
never
a
dull
moment
that
comes
to
complicated
systems
like
this.
I
just
want
to
show
you
one
or
two
other
things.
First,
this
the
transverse
you
can
see
here
in
the
transmit
subsystem
is
putting
out
10
gigahertz
and
we're
running
10
gigahertz
from
the
this
little
antenna
to
that
little
antenna
just
a
few
feet,
but
there's
also
uhf
on
both
sides.
And
how
do
you
know
that
it's
not
the
uhf
leaking
across?
B
B
B
B
Look
at
the
pie
chart
now
with
this
full
hd
signal
that
I'm
encoding
on
the
fly
rather
than
carefully
encoding
offline,
I'm
using
34.5
percent
of
the
signal
to
send
the
video.
So
my
video
data
rate
is
about
6
million
bits
per
second,
but
I've
still
got
11
and
a
half
million
bits
per
second
that
I'm
wasting.
