From YouTube: 20211112 Orbit Workshop 2
Description
Second Orbit Workshop after Debris Mitigation meeting with FCC on 28 October 2021.
A
For
debris,
as
well
as
as
well
as
frequency
management,
it's
uniquely,
I
think
there
are
a
few
other
countries
that
are
doing
it
following
the
the
path
that
the
the
f
the
us
did,
but
it's
certainly
not
clear
that
you
would
file
a
license
anywhere
and
have
to
deal
with
the
fcc
equivalent,
like
I,
for
instance,
in
the
uk,
it's
definitely
different.
You
don't
have
to
file
with
ofcom.
A
Oh,
that,
that's
that's
really
old
advanced
published
information
has
been
required
way
back
when,
and
I
mean
art,
feller
and
ray
sofia
used
to
talk
about
that
all
the
time.
So
they
would
ask
me
in
particular:
hey.
Could
you
give
us
this
information,
so
we
can
give
it
to
the
fcc,
and
so
all
right
filled
out
a
like
a
letter
format
and
gave
it
to
them,
and
presumably
they
gave
it
to
the
fcc.
B
A
A
A
B
A
B
B
A
You
have
your
first
first
part
of
your
system
in
line
and
then
then
that
allows
others
when
the
notice
comes
out
that
allows
other
countries
to
sort
of
say:
look,
we've
got
these
systems
in
line
to
use
that
spectrum
too,
and
we
we
need
to
work
with
you
to
share
it.
So
it
goes
into
what's
called
coordination
status,
then
you
have
to
coordinate
with
whomever
it
is
that
you
got
to
coordinate
it
with
somebody's
got
a
satellite
in
germany.
B
A
B
B
A
B
B
A
Well,
it
existed
the
parts
of
it
there's
a
thing
called
das
202.
I
think
it's
a
part
of
odar
that
existed
before
it's
a
nasa
document
and
it's
still
maintained
and
kept
evergreen
by
nasa,
not
by
by
fcc,
so
nasa
fcc
will
defer
to
nasa
on
detailed
specific
issues
associated
with
yeah
atmospheric
drag
models
and
all
kinds
of
detailed
scientific
stuff
that
the
fcc
okay,
so
you
so
I
actually
we've
had
to.
A
A
Right,
that's
where
we
that
triggers
all
sorts
of
others
yeah
the
place
where
we
wouldn't
be
treated
like
a
part.
Five
is
there's
a
part
of
the
radio
regulations
called
4.4
and
4.4
of
the
radio
regulations
says
an
administration
can
authorize
use
of
spectrum
in
non-compliance
with
the
table
based
on
its
own
needs,
but
it
needs
to
provide
deference
to
any
interference
that
is
cost
to
anyone.
Who's
operating
in
accordance
with
the
table.
B
A
Is
like
primary
secondary
and
no
status
at
all.
In
other
words,
you
you're,
not
even
even
a
secondary
user,
would
have
preference
to
somebody
who
files
under
4.4.
All
of
the
universities
are
using
amateur
spectrum
but
they're
filing
under
4.4,
and
what
that
means
is
the
fcc
has
said.
Okay,
then
you
have
to
in
addition
to
filing
your
license.
You
have
to
go
coordinate
with
the
iaru
satellite
committee.
A
So
that's
what
all
all
the
guys
in
amsterdam
were
doing
is
coordinating
all
the
university
satellites
that
were
applying
on
these
part
fives
and
and
what
we
would
do
is
just
take
them
in
in
in
order
and
just
assign
them
to
a
frequency
chunk
right
in
the
middle
of
the
3
435
to
438
frequency
band
around
437,
I
think
4
37
5
to
4
yeah
437
to
437
5..
We
put
every
one
of
them
in
that
band
and
then
use
the
rest
for
ourselves
yeah.
B
A
B
A
No
they're
they're
not
at
all,
and
I
suppose
they
shouldn't
well
to
to
compare
to
compare
what
we're
doing
to
the
status
quo,
probably
best
to
have
just
have
a
look
at
part.
25
of
the
commission's
rules,
47
cfr,
part
25
and
you'll
you'll-
see
that
there's
a
pretty
healthy
body
of
material
that
you
have
to
get
through
to
to
file
for
a
commercial
satellite
system.
A
A
Yeah
yeah
yeah
and
I'm
not
even
sure
it
helps
them
a
lot
anyway.
The
the
point
is:
even
if
you
look
at
part
five,
you
can
go
online
and
and
talk
and
look
at
it
and
experimentalize
and
there's
a
form
you
fill
out
now
that
form
wasn't
ever
intended
for
satellites,
so
you
have
to
yeah
to
do
something
very
different
to
fill
out
that
form
you
have
to
have
to
do
things
that
were
never
intended
on
the
form
to
get
it
to
file
properly,
and
it's
a
it's
a
it's.
A
B
A
It
it
it's
it's
as
it
was
intended
to
be,
and
it
there
are
the
parts
it
refers
to
the
part,
25
sections
that
you
can
go
and
refer
to,
and
it's
easy
enough
to
learn
to
fill
out.
So
what
I'm
thinking
is
we
need
something
like
a
new
form
like
a
part,
5
form
only
one
for
satellites,
and
I
would
think
we
should
volunteer
to
create
the
form.
It's
not
that
hard,
and
we
know
what
bands
we
want.
A
B
A
And
after
all,
if
you
think
about
it,
it
makes
sense
because
parts
of
the
land,
mobile
radio
community
regulate
themselves
and
the
amateur
raider
community
regulates
itself.
I
mean
so
why?
Why
not
do
the
same
for
satellites
as
long
as
we
comply
with
the
the
itu
part
of
it,
which
is
a
little
bit
more
unique
for
satellites,
but
what
they
have.
A
A
If
you
want
to
see
what
one
of
those
looks
like
you
there
there,
it
is,
and
by
the
way
that
one
I
sent
you,
we
use
the
same
thing
every
time
and
time
again
I
mean
there's
a
whole
thing
about:
will
your
batteries
explode
and
and
create
debris
in
space
and
all
this
stuff?
That's
not
gonna
happen.
You
actually
have
to
do
that
one
time
and
then
you
file
the
same
thing
over
and
over
again.
A
The
thing
that's
different,
of
course,
is
the
orbit
stuff
and
it's
the
das
202
document,
the
nasa
part
where
you
have
to
fill
in
altitudes,
and
the
thing
you
have
to
calculate
is
the
surface
area
projected
into
the
velocity
vector.
In
other
words,
what's
the
drag
on
the
satellite
and
from
that
drag
you
can
estimate
the
lifetime
yeah
and
all
that
there
are
standard
formulations
in.
Do
you
know
words,
it's
called
snad
system.
A
A
After
that,
I
think
it'll
be
standard,
plump
the
numbers
in
and
hope
it
doesn't
come
out
greater
than
six
years.
Pro
part
of
the
problem
is
orbits.
If
the
orbits
get
higher
than
about
550
kilometers,
it's
hard
to
make
them
re-enter
in
less
than
six
years,
and
that's
the
that's
what
the
fcc
thinks.
The
right
answer
is
whether
it's
right
or
not,.
B
A
A
B
Right,
yeah
tracking
the
return
on
investment
return,
just
a
straightforward
cost,
based
turnout,
return
on
investment,
but
also
tracking
the
capability
return
on
investment
and
what
that
offers
the
community
and
what
that
can
offer.
You
know
just
for
education
and
all
that
that
that
value
you
have
to
track
it
and
that'll.
Give
you
two
different
time
horizons,
and
you
know
whichever
one
you
want
to
exploit
is
the
one
you
go
for.
A
A
B
A
A
B
We
need
to
do
in
order
to
get
you
to
say.
Yes,
basically,
you
know
you
know
in
a
roundabout
way,
because
you
can't
really
just
say
well
and
they're
not
going
to
pre-approve
anything.
We
already
know
all
that,
but
the
the
way
is
clear,
but
the
they
will
scrutinize
the
disposal
plan
and
the
disposal
plan
is
really
the
mission
plan
and
we
have
to.
A
Imply
that
by
virtue,
if,
if
and
when
you
actually
had
such
a
mission,
you
would
put
all
that
information
in
even
in
narrative
form
into
the
odor
look
at
what
I
gave
you
and
and
basically
it's
your
disposal
plan
and
that
that
is
you
put
it
into
that
42
42,
514,
kilometer
radius
orbit,
and
that
way,
that's
not
the
altitude.
That's
the
radius
of
the
orbit.
B
A
B
So
short
answer:
no,
we
did
not
promise
anything.
We
were
very
careful
not
to
do
that.
We
just
promise.
We
understand
that
we
heard
loud
and
clear
that
we
have
to
comply
and
they
were
really
kind
of
thrilled
that
we
were
saying
that
and
we
that
we
were
wanting
to
do
non-traditional
orbits
and
we
wanted
to
get
some
guidance
back,
that
the
were
these
okay,
you
know
and
about,
though
so
yeah
so.
A
So
so,
there's
there's
really
two
things
that
satellites
are
going
to
then
have
to
have
in
in
this
modern
space
era.
One
is
some
kind
of
well
yeah:
either
a
drag,
a
differential,
drag
system
or
or
and
a
a
propulsion
system.
So
we
should
have
a
serious
discussion
about
what
are
the
technologies
that
we
can
get
our
hands
on
yeah.
A
In
our
email
yeah,
I
I
mean
astro
digital's
had
a
lot
has
flown
quite
a
few
missions
that
are
just
to
demonstrate
propulsion
systems
and
they
haven't
been
good
outcomes.
A
lot
of
the
missions
we've
flown
for
for
a
client's
system
flat
out,
didn't
work,
so
we
need
to
take
somebody
like
astro
digital
and
sit
down
with
and
say:
hey,
hey
guys,
like
kyle,
what
who's
the
radio
amateur,
what
what?
A
What
technology
should
we
be
looking
at,
that
are
cost
effective
and
actually
work,
and
what
kind
of
thrust
can
we
get
out
of
them?
Because
we
need
to
know
if
we
can
do
this
in
a
day
a
week
or
years
to
apply
some
delta
v
like
say
10
meters
per
second?
Does
it
take
a
day
to
do
that?
Does
it
take
a
week
to
do
that?
Does
it
take.
