Description
Jan King, Wally Ritchie, and Michelle Thompson discuss orbit strategies and other subjects during an ORI Office Hours recorded 12 May 2021.
B
B
A
A
B
A
A
It's
it's
the
first
place
where
it's
documented,
for
you
know
god
and
all
his
children
to
see.
I
mean
it's
it's.
It
was
really
a
very
popular
npr,
so
everybody
saw
what
they
were
saying
there,
but
they
have
the
the
more
the
more
damning
ones
were
actually
those
that
were
used
in
proceedings
where
they
filed
against
some
company.
A
So
so
they
were,
they
were
commenting
in
in
a
reply
comment
cycle
to
somebody
else's
application
and
there
they
would
go
after
more,
more
specific
saying
they
didn't
want
their
their
orbit
altitude
crossed
by
this
other
satellite
applica.
You
know
this
other
satellites
system
and
therefore
the
license
should
not
be
granted,
so
they
were
tying
the
spectrum
issue
to
the
very
specifically
to
the
debris
issue,
and
I
wanted
to
get
one
that
was
more
exact,
but
this
one
exactly
says
what
we're
claiming.
A
A
Yeah,
okay,
yeah
all
right
so
so
then
I
sent
you
a
a
powerpoint
which
had
all
the
delta
v
stuff.
So
if
you're
talking
to
I
mean
that
was
so,
you
can
use
that
for
discussion
with
others
about
propulsion
systems,
but
also
I
wanted
to
show
that
to
the
commission.
So
they
could
see
what
the
consequence
would
be
for
for
the
small
satellite
service
to
use
this
class
of
a
system
that
it
it
was
neither
big
or
small,
it's
kind
of
like
a
medium-sized
rocket
motor.
B
A
And
with
the
bus
technology,
that's
around
these
days,
you
know
where
almost
every
satellite
has
a
three
axis
attitude
control
system
and
I
think
we're
gonna
have
to
have
one
too.
It's
not
such
a
big
deal
at
all,
just
to
at
apogee
point
the
rocket
motor
and
do
a
do
a
firing
whenever
we
need
to
do
it,
but
I
mean
it's
still:
it's
still
something
we
wouldn't
have
to
do
have
had
to
do
in
the
past.
We
weren't
obliged
to
do
in
the
past.
A
The
third
thing
I
sent
you
was
a
confirmation
of
the
delta
v
that
we
produced
from
phase
three,
and
I
I
wanted
to
get
that
before
the
commission,
so
they
could
see.
Look
these
guys
have
done
some
pretty
significant
things.
In
fact,
they
hold
the
record
for
the
largest
delta
v
maneuvers
ever
performed
by
a
non-professional
spacecraft.
B
A
And
the
link
budget's
what
I
really
wanted
to
spend
the
bulk
of
the
time
talking
with
you
and
wally
about
and
I'm
opening
it
here,
all
righty.
Now.
What
I
wanted
to
do
is
review
sort
of
the
philosophy
that
I've
been
using.
So,
let's,
let's
kind
of
go
through
that
and
and
if
it
let
me
know
where
there's
there's
a
departure
in
the
approach
or
concept.
A
A
C
Yes,
so
far,
except
for
the
you
know
this
concept
of
direct
to
disposal
orbit
in
geo
that
eliminates,
I
think,
a
lot
of
the
issues,
because
you're
essentially
launching
yourself
into
as
a
cubesat
being
ejected
from
an
upper
stage.
Canister.
Even
if
you
have
total
failure
right
out
of
the
gate,
you're
in
disposal
orbit.
B
A
Idea
was
to
do
and
here
so
I'm
not
saying,
we'd,
never
use
a
geo
orbit
and
I'm
not
saying
we'd
never
use
a
a
leo
orbit.
We
would
want
to
continue
doing
that,
but
we
we
have
to
comply
with
the
constraints
that
the
commission
is
putting
on
all
other
services,
including
ours.
To
do
that
so
we'd
have
to
live
with
that,
and
is
that,
okay
with
us-
and
I
think
you
know
what
I
was
suggesting-
we
say
the
commission
is
yeah.
Well
we'll
do
those
and
we'll
comply
with
your
rules,
but
that
does
mean.
A
C
C
C
B
That's
the
sort
of
this
is
the
sort
of
question
that
that
can
more
easily
be
explored
in
this
process
of
of
making
a
presentation
and
getting
them
to
know
us
and
starting
to
to
introduce
the
fact
that
we
have
all
of
these
the
capacity
for
experimentation
and
trying
new
things.
So
it
may
be
that
they
go.
B
What
no
you
know,
yeah
hey,
think
about
it,
a
little
bit
more
and-
and
you
know
just
let
it
sit
for
a
while-
and
we
may
end
up
being
able
to
you
know
socialize
this
idea,
you
know,
but
I
I
fully
expect
a
lot
of
it.
A
lot
of
it
to
have
so
eyebrows
will
be
raised.
Questions
will
be
asked.
We
need
to
be
prepared
to
be
innovative,
but
also
back
it
back
it
up
with
the
data,
and
I
think,
we're
doing
a
really
good
job
there.
Well.
A
A
B
A
They'll
push
back
as
iridium
has
done
in
the
past.
The
second
group
is
the
is
the
long
knife
sharp
group
which
is
the
geo
group.
Those
are
those
are
the
kings
of
the
hill.
Those
are
the
guys
who
make
all
the
money
and
have
all
the
attention
of
the
commission
and
every
of
in
the
itu,
and
they
probably
will
will
have
something
to
say
about
us
occupying
a
geo
position
at
all
right
and
modifying
that
position
to
go
up
or
down.
A
You
can
pretty
well
expect
that
they'll
have
something
to
say
about
it,
I'm
just
guessing
at
this
now.
This
is
my
my
educated
guess,
whereas
if
we
do
some
other
in
between
cases
that
you
know,
they've
got
a
lot
to,
they
got
a
lot
to
answer
for
they're
already
taking
the
the
cream
off
the
top
they're,
always
they're
got
getting
the
best.
A
Orbits
are
calm,
they
can
hardly
complain
if
we
try
and
find
a
solution
for
ourselves
where
we're
transitioning
from
one
one
thing
to
another,
and
if
we
cut
come
up
with
an
invented
strategy
where
we
don't
affect
the
leos
and
we
don't
affect
the
geos
at
all.
Well,
you
know
what
can
they
say?
So
that's
that's!
That's
sort
of
the
strategy,
I'm
I'm
I'm
thinking
of
here.
A
Yeah
but
funny
enough,
all
the
government
agencies
will
be
our
allies
here
because
they
want
to
use
space
too
and
the
greedy
and
the
greedy
operators,
com
operators,
all
of
them
gto
and
ng.
Gso
and
ngso-
are
all
taking
the
prime
space
and
then
they're
bitching
about
other
people
using
space.
Well,
that
just
doesn't
fly
and
we've
got
to
make
sure
I
mean
we
could
be
the.
We
may
be
the
fly
in
the
ointment,
but
we
can
be
a
pretty
nasty
fly
and
making
this
point
that
everybody's
got
the
right
to
space.
C
A
You're
gonna
have
essentially
just
as
effect
almost
as
effective
coverage
as
you
would
with
a
geo
a
a
geodrifter,
but
but
you
know
even
both
of
those
orbits
are
cool
and
it
stays
out
of
harm's
way.
So
you
know
I
I
wouldn't
mind
adding
that
one
to
the
list,
but
I
do
think
if
you're
fooling
around
with
propulsion
systems
and
you're
at
the
geo
arc,
there's
just
going
to
be
a
a
reaction
from
the
geo.
A
A
They
have
no
idea
that
we
perform
more
complex
propulsion
maneuvers
than
they
ever
thought
about
doing,
but
they
don't
know
that
for
a
fact
and
they
they
can.
We
can't
show
the
uniformity
and
consistency
that
they
have.
We
don't
have
billions
of
dollars,
so
you
know
it's
just
I
would
say,
go
for
it,
michelle
go
for
it
and
put
both
of
those
orbits
in
as
a
candidate.
B
A
A
C
A
You
could
be
clever
if
you
have,
if
you
have
delta
v
to
start
with,
and
I
think
for
a
geo
you're
going
to
have
to
have
some
delta
v
by
the
way.
There's
another
way
to
do
it,
which
is
the
hosted
payload
idea
like
like,
like
msdl,
did
on
on
oscar
at
100.
that
that
mode
always
exists.
If
you
can
talk
somebody
into
paying
for
it,.
B
B
C
A
C
A
B
A
A
I
I
I
often
think
about
that,
but
but
to
me
it
it
it's
hard
for
me
to
erase
all
the
phase
three
stuff
or
phase
three
phase
four
stuff
from
my
mind,
where
we
were
always
talking
about
bigger
spacecraft,
but
a
6u
at
geo
would
perform
the
same
as
a
6u
gto
at
apogee
right.
So
it's
the
apogee
case
and
we're
going
to
talk
about
that.
One
here.
A
B
A
B
A
A
C
A
A
A
I
don't
know
if
we've
been
to
going
down
to
two
meters
anymore,
because
that's
a
pretty
big,
pretty
pretty
long
antenna,
but
it
could
be
done,
but
anyway,
so
idea
of
having
a
perigee
transponder
and
an
apogee
transponder,
so
that
that
idea
sort
of
lingers.
In
my
mind,
it's
just
something
for
you
guys
to
think
about.
A
A
B
A
A
B
A
So
the
attitude
control
system
has
got
to
work
a
little
harder
and
anyway.
The
whole
thing
is
that
such
such
a
millimeter
weight
transponders
isn't
it.
It
is
a
com
system,
as
opposed
to
a
data
delivery
system.
That
would
be
another
thing:
we're
just
delivering
data
to
one
point
on
the
ground,
but
we're
not
we're
trying
to
talk
to
as
many
radio
amateurs
as
we
can
as
this
thing
flies
over.
A
A
A
And
somebody
like
the
fcc
or
you
know
any
other
administration
in
the
world
can
look
say:
oh
yeah,
that's
our
amateur
community
and
they
have
this
this
great
little
system
they
use
and
they're,
making
good
use
of
their
spectrum
that
that's
the
kind
of
thing
I'd
like
to
do
so
it
means
we
need
kind
of
an
operational
service
and,
of
course,
there's
all
the
other
stuff
michelle.
That
goes
with
that,
like
fundraising
and
donations
and
gifting,
and
all
that
that
would
be.
You
know
consistent
with
not
not-for-profit
organizations.
B
A
What
what
were
what
we're
selling
down
the
river
a
little
bit
that
amsat
was
always
really
good
at
during
my
during
my
watch
was
we
were
always
generating
new
technology,
and
we
there
was
nobody
who
was
developing
more
technology
for
space
than
we
were,
and
I
honestly
literally
think
now
thinking
back
on
it.
We
really
kick-started
the
small-side
world
by
the
technology
work.
A
We
did
during
those
phases
thanks
mostly
to
karl
meinzer,
and
I
would
give
martin
sweeting
a
lot
of
credit
there
too
and
others,
but
but
but
we
that
that
part
would
be
a
little
bit
backpedaled
to
getting
an
operational
service
here.
We,
it
would
always
be
nice
as
we
go
forward
to
have
something
new
on
every
spacecraft.
If
we
could.
A
B
A
Yeah
yeah
and
getting
more
with
the
the
one
webs
and
spacex
of
the
world
trying
to
grab
everything
they
can
and
5g
cellular.
As
you
be
aware,
okay,
so
we
you
know
back
in
2014
and
15
phil
carn
and
I
were
beating
this
whole
thing
to
death
regarding
digital
transponders
and
stuff.
I
was
working
at
work
on
millimeter
wave
stuff
and
having
a
lot
of
fun
and
enthusiastic
experiences
with
millimeter,
wave
and
phil
khan
has
always
been
pushing
that
direction
and
obviously
digitally
so.
A
After
a
lot
of
thought,
we
came
up
with
these
two
frequency
bands.
Tom
clark
was
throwing
his
ore
in
the
water
and
he
was
pushing.
He
said
you
know
that
24
gigahertz,
the
the
the
rain,
the
rain
is
going
to
kill
you
there.
The
and
the
excess
path
loss
is
going
to
be
awful.
You'll
find
I
think
that
you're
better
off
at
10
10.5
and
just
forget
about
anything
higher
than
that,
and
he
and
I
both
disagreed
and
agreed
on
that
point,
and
I,
when
I
did
this
link
budget,
which
is.
A
It's
hard
to
talk
about
this
in
one
in
one
swoop.
This
is
sort
of
like
an
evolution
of
15
or
20
years
of
work
here,
but
it's
I
it's
both
commercial.
I
it
started
as
an
amateur
link,
the
spreadsheet.
Then
it
became
work.
Then
it
became
amateur
again.
It's
it's
gone
back
and
forth
about
five
times,
so
this
is
actually
the
best
one
I've
ever
developed
and
it's
I
took
the
most
advanced
work
one
and
I
added
some
beans
technology
to
it,
so
that
now
the
amateur
one
is
the
best
one.
I've
ever
done.
A
A
This
is
the
better
choice
for
for
trying
to
do
this
and
it
it's
always
something
you
have
to
think
of
is
what
r
d
does
the
user
have
to
use
to
get
on
this
thing?
Are
you
going
to
use
the
do
the
r
d
for
that
that
group
of
users,
or
you
know,
are
you
going
to
make
kits?
How
are
you,
how
are
you
going
to
approach
the
user
community
using
this
box
in
the
sky.
B
A
B
We
could
go
the
other
way
here.
We
definitely
could.
The
the
reason
which
you
probably
share
is
that
the
way
that
our
license
and
the
way
our
service
is
set
up
is
that
everybody
should
be
able
to
receive.
So
you
don't
get
people
that
want
to
transmit
without
people
hearing
it
and
that,
if
you
make
it
easy
to
receive
the
r
d
is
that.
A
B
It
all
falls
out
of
of
a
variety
of
assumptions
about
the
service
about
operations
about
building
the
community,
because
we
really
have
to
build
it
up
from
almost
scratch.
At
this
point,
the
right
now
amateur
satellite
means
going
out
with
an
air
antenna
and
doing
a
leo
pass
and
there's
no
time
to
develop
a
community.
You
have
barely
time
to
trade,
call
signs
and
people
don't
even
have
time
to
write
it
down.
They
just
record
it
every
lots
and
lots
of
schedules
that
are
set
up
in
advance.
B
B
Every
week
I
tune
in
to
the
qo
100
net
on
batc,
and
I
listen
to
the
round
table
of
everybody
so
excited
about
tweaking
their
station
or
experimenting
with
their
equipment
or
learning
new
operating
styles
or
discovering
something
cool
about
the
transponder,
and
I
can
see
evidence
all
over
twitter
and
reddit,
and
you
know
talking
to
people
all
the
time
about
what
a
true
revolutionary
thing
q0100
has
been.
It
is
building
a
community
and
it
is
building
skills
every
week.
B
That
goes
by
that
we
don't
have
something
like
that
feels
like
we
are
falling
more
and
more
behind
and
part
of
that
is
an
illusion.
You
know
we
will
get
there.
We
can
do
it.
You
know
and
even
though
it's
far
away-
and
we
can't
see
it-
we
can
still
benefit
from
all
the
development
and
and
and
what
have
you.
But
we
are
going
to
have
to
build
that
sort
of
same
sort
of
community
from
zero
here
and
that's.
A
A
Like
that
to
happen,
and
and
and
what
you're
saying
is
absolutely
borne
out
by
by
by
that
in
that,
we
have
to
be
ready
to
fill
that
slot
when
things
start,
we
don't
know
what
the
demise
of
that
thing
could
be.
If,
if
an
sspa
fails,
they
could
be
off
the
air
tomorrow
instantaneously,
if
they
haven't
got
redundancy,
probably
have
some.
B
You
know
assumptions
the
way
that
they
have
worked
for
for
forever
coming
around
to
being
truly
open
is
especially
the
way
that
things
kind
of
changed
between
dl
and
na
you
know,
since,
since
these
projects
you
know,
itar
really
destroyed
it.
So
to
pop
up
and
say:
look
we
fixed
the
problem,
here's
the
regulatory
results.
You
know
we
have
a
ways
to
go
to
develop
a
really
good
collaborative
sort
of
deal
with
amset
dl,
and
that
might
not
ever
happen
and
that's
fine.
B
A
Yeah,
no,
the
these
spacecraft
routinely
the
big
geos
are
purchased
with
a
15-year
warranty.
So
if
they've
handled
the
way
they
built
that
payload
the
way
they
build
usual
geo
transponders,
then
they'll
have
made
dull
system
redundant
in
bits
and
pieces,
and
since
this
was
done
by
a
a
commercial
company
for
amsa,
dl,
yep,
okay,
so
so
there's
there's
a
lot
of
things
going
on
to
to
say
there.
A
First
of
all,
that
probably
means
that
the
system
is
redundant
and
probably
elements
of
the
transponder
are
redundant
like
lnas
and
sspas
are
redundant
in
there.
So
that
really
increases
the
probability
that
you
will
get
a
very
long
lifetime
out
of
it
second
comment:
is
it
it?
It
becomes
an
us
versus
them,
partly
because
of
the
satellite
geostationary
position
that
you
can't
do
anything
about
that's
a
problem
with
one
geo
spacecraft.
It
can
never
be
a
global
community
system
and
okay,
yes,
you
can.
A
B
A
A
They
want
to
do
their
own
thing
and
they
have
their
own
agenda,
which
means
that
we're
going
to
have
the
unusual
circumstance
where
there
could
be
two
or
more
viable
amateur
satellite
organizations
in
the
united
states,
the
united
states,
not
a
third
world
country,
but
the
united
states
having
more
than
one
organization
that
will
confuse
the
hell
out
of
the
world
to
some
extent
and
it
I
don't
think
it's
a
slam
dunk
that
ori
can
just
plug
in
and
say:
oh
we're,
the
new
amps
at.
I
don't
think
it's
going
to
work
that.
B
A
A
B
B
We
are
a
research
institute.
We're
set
up
to
do
r
d.
We
are
not
a
membership
organization.
We
chose
specifically
not
to
be
that
in
order
not
to
compete
with
amsat
we're
here
to
help
all
amsat
organizations
and
anyone
else
that
wants
cool
r
d
stuff
to
happen.
You
know
for
for
amateur
space
and
terrestrial,
as
you
can
repeat
this
message
over
and
over
again,
but
if
people
choose
to
view
you
as
existential
threat
or
competition,
then
all
you
can
do
is
keep
repeating
your
message
and
not
act
like
it.
B
A
B
And
we
just
refuse
to
feud
yeah,
it's
just
that's
the
only
real.
That's
a
really
really
strategy
that
we
have
is
to
just
keep
repeating
the
message:
keep
showing
up
and
providing
good
work
for
free,
and
you
know
committed
to
the
technology,
advancing
the
state
of
the
art,
doing
fun,
innovative
things
and
not
doing
anything
that
would
look
like
replacing
or
competing
with
any
of
the
amsat
organizations.
