A
So
what
I
have
for
today
is
we
know
that
we
need
to
adjust
the
orbit
to
stay
above
1250
kilometers
and
something
that
we
need
to
do
is
go
ahead
and
model.
This
I'm
most
familiar
with
gmat
the
from
nasa
to
open
source
mission,
analysis
tool,
it's
pretty
cool,
but
there's
lots
of
other
choices.
So
what
I'm
looking
for
and
what
I
put
the
word
out
is
help
with
getting
possible
orbits
into
gmat
or
whatever
people
prefer,
and
then
we
can.
What
that
will
do
is
it'll.
A
That's
the
first
thing.
The
second
thing
is
engine
repository
I
did
not
see,
I
don't
see
the
engine
repository
work
published
yet
and
then
the
final
thing
that
I
have
is
the
final
specific
thing
that
I
have
is
to
talk
about
the
high-level
communications
architecture
block
diagram,
so
we
do
have
one
I'm
going
to
go
ahead
and
show
I'll
put
the
presentation
up
here,
and
here
is
our
I'm
leaping
ahead
to
page
12..
This
is
the
original
block
diagram
and
it
has
a
lot
of
information
on
it.
A
A
So
we
have
plenty
of
decision
making
to
do
and
every
additional
frequency
that
we
support
makes
it
more
complicated,
of
course,
but
there's
nothing
stopping
us
from
from
picking
from
from
those
four
different
recommended
frequencies,
and
then
the
board
on
the
left
is
the
we
call
it
the
fpga
processor
board.
It's
essentially
a
digital
board.
The
the
thing
about
this.
This
was
developed
by
dr
christopher
bridges
and
me
and
then
a
whole
bunch
of
other
people
is
that
it
has.
A
So
it's
essentially
a
simpler
transponder
and
so
covid
slowed
down
the
process
of
testing
this
in
the
lab.
But
with
this
particular
proposal
you
know
with
with
us
working
on
it.
I
think
that
we
should
revive
the
the
test,
the
demonstration
of
the
switches
in
place,
rf
switches
and
and
show
the
failover
mode.
A
So
that's
that's,
probably
the
the
thing
that
that
that
is
most
unique
about
this
particular
architecture,
so
otherwise,
without
the
the
failover
mode,
it's
a
pretty
straightforward,
digital
multiplexing
transfer
or
transponder.
The
orbit
part
I
added
a
page
for
for
orbit
for
north
america,
but
I
I
put
the
mission
orbit
for
for
japan.
First,
we
talked
about
that
last
week.
This
is
the
part
that
we'll
need
gmap,
for
I
reached
out
to
amsat
dl
for
help
with
gmat,
because
they've
helped
in
the
past,
with
the
orbits
for
the
lunar
missions.
A
A
B
A
B
A
B
A
A
So
I
don't
know,
but
I
don't
think
so-
we'll
generally
spend
most
of
our
time
at
the
high
high
altitude
and
then
swoop
down
to
hopefully
1250
or
higher
and
then
back
up
and
stay
stay
at
a
high
altitude
for
longer,
and
that's
that's
about
it.
That's
what
that
is
the
a
good
limit
of
what
I
know
about
about
the
orbit.
A
A
A
Are
all
high,
you
know
higher
orbit
satellites?
These
are
you
know
so
so
the
answer
is,
is
yes,
it's
been
done
before
and
it's
about
time
that
we
should
do
it
again
and
there's
been
so
many
advances
in
all
sorts
of
technology.
It's
you
know
so
so
I
think
that
we
can.
We
can
achieve
this.
It's
we've
done
it
before
and
we
should.
We
should
be
doing
it
again.
These
you
know
very
popular
and
and
a
completely
different
experience.
A
This
is
pretty
pretty
early,
I
would
say,
and
that
would
be
completely
up
to
the
the
organization
that
that
accepted
the
proposal.
So
what
we're
hoping
to
do
is
to
provide
as
much
horsepower
as
we
possibly
can
on
the
r
d
side-
and
you
know,
with
with
engineering,
volunteers
and
and
prototyping
and
developing,
and
you
know,
learning
and
producing
things
that
that
can
survive
in
space.
That's
that's
our
goal
in
terms
of
like
launches
and
and
things
like
that,
we
look
towards
other.
A
You
know
we
will
be
submitting
this
to
jamsat
the
japanese
amsat
organization.
It's
it's
intended
to
be
presented
to
them
and
if
they
decide
to
to
accept
it,
then
securing
a
a
launch
and
and
and
telling
us
what
we
need
to
do
in
order
to
to
help
with
that.
That
would
be
their
their
responsibility,
their
choice
and
we
would
just
help.
However,
we
can-
and
you
know,
despite
challenges
with
kovid
we've-
we've
had
a
a
pretty
good
run
of
of
successes
here.
A
Lately,
there's
been
some
setbacks,
of
course,
but
the
down
link
part
is
is
coming
together
for
the
digital
board
and
the
propulsion
part
is
is
coming
together
with
some
some
good
good
engineering.
That's
the
electric
motors
that
we're
looking
at
are,
or
the
electric
propulsion
that
we're
looking
at
is
flown
twice
before
you
know
advanced
that
design
just
a
little
bit
more,
because
what
we're
going
to
do
is
to.
A
Show
that
the
electric
propulsion
is
is
very
compatible
with
with
broadband
communications,
because
we
we
have
a
method
to
synchronize
the
the
engines.
So
that's
exciting.
That's
a
pretty
cool
thing
and
we've
very
fortunate
that
we
have
this
opportunity
and
want
to
take
full
advantage
of
it.
The
thing
that
we
don't
yet
have
that
we
didn't
have
last
week-
and
we
still
don't
have
this
week-
is
any
real
human
resources
that
can
do
thermal.
A
This
is
not
unusual
because
it's
it's
in
the
amateur
satellite
community,
thermal
design
has
been
been
pretty
short-handed
on
thermal
design.
It's
it's
very
specialized
and
we're
extremely
been
extremely
lucky
in
the
past
to
have
a
few
people
that
were
very
competent
at
it
and
and
donated
their
time,
and
we
don't
have
anybody
that,
I
would
say,
was
an
expert
in
in
thermal
design
and
that'll
be
kind
of
a
big
deal.
A
We're
talking
about
a
you
know,
so
we're
talking
about
a
6u
spacecraft
and
it's
got
to
pack
everything
in
there
and
really
have
to
be
careful
about
about
thermal
design.
So
that's
that's
something
that
I've
I'm
working
to
try
to
to
identify
people.
We
do
have
a
volunteer
who's
willing
to
to
give
it
a
shot.
It's
it's
something
that's
going
to
need
some.
I
think
some
expert
attention
or
review
early
and
often
to
figure
out
if
it'll
work.
So
that's
that's
something
I'm.
A
I
think
that
probably
most
concerned
about
the
the
thermal
and
the
mechanical
part
since
in
general,
what
what
we
do
at
ori
is
digital
communications.
So
the
communication
side
of
it,
I
think
we're
we're
coming
along.
The
downlink-
is
took
some
big
steps
forward
just
over
the
past
few
months
and
the
uplink
has
is
starting
to
to
come
along
too
that's
rapidly
coming
together.
A
We're
looking
at
like
doing
quality
of
service
and
multiplexing
based
on
the
type
of
traffic
and
adaptive
coding
and
modulation,
to
include
that
and
the
authorization
and
authentication
stuff
has
been
so
started
to
publish
and
circulate
that
to
try
to
get
some
really
good
reviews
and
that's
come
along
quite
quite
a
ways.
I
have
a
poster
session
about
that
at
home.
Expo.
B
A
It
does
interfere
it
will
it.
That's
what
I
hear
that
I've
been
assured
that,
yes,
they
will
interfere
and
probably
the
I
mean.
Obviously
the
solution
is
either
you
can
either
you
can
fire
your
your
your
engines
or
you
can
you
can
communicate
so
so
what
we're
we're
doing
is
is
synchronizing
the
the
engines
in
a
particular
way
that
allows
more
communications
to
happen.
A
B
A
Yes,
I
think
that
would
be
you
know
well
to
me
it's.
It
doesn't
work
until
you
test
it
live
over
the
air.
So,
yes,
we
would
build
all
this
stuff
up.
I
think
we'll
be
okay,
it
it
will.
None
of
this
is
easy
things
worth
doing.
Rarely
are,
but
we'll
be
in
we'll
be
in
good
shape
if
we
could
get
to
the
point
where
we're
doing
so
much
of
this
work
that
we
we
need
to
build
our
own
chamber,
then
that
be
a
raging
success
and
I
would
I
would
think
good
for
us.
A
I
don't
anticipate
that
because
you
know
when,
when
jan
king
talks
about
this
particular
this
proposal,
this
idea
of
of
heo
he
he
really
does
think
of
it
as
a
small
fleeter
or
essentially
a
constellation.
So
in
his
mind
we
need
as
an
amateur
satellite
service,
we
really
need
to
have
multiple,
multiple
helos,
and
you
know
maybe
three
or
four,
and
that
would
give
you
global
coverage-
and
you
know
after
thinking
about
this-
for
for
a
bit.
A
A
A
B
And
was
able
to
actually
pick
up
some
of
their
telemetry
signals
on
the
on
the
light
sail
that
they
had,
and
so
I
thought
that's
such
an
innovative
idea
of
using
the
the
light
propulsion
with
the
lights.
Of
course,
it's
kind
of
a
specialized
proportion
system
that
maybe
maybe
requires
something
more
experimental,
probably
better,
better
driving
through
thruster
systems
that
are
used
in
satellites
but
but
gosh.
That
would
be
a
nice
thing
in
the
far
future
to
maybe
have
something
that
would
provide
that
kind
of
ability.
