Project meeting about the AmbaSat re-spin (board moved to 70cm)

We
have
hardware
out
in
the
field
and
happy
students,
it
looks
like
things
packets,
zipping
around
in
the
lab
and
we're
still
we
haven't
destroyed
our
chances
with
the
sounding
rocket
so
which
is
great,
that's
awesome
and
then
jan
king
was
very
very
interested
in
us
using
this
as
a
way
to
sort
of
assess
out
a
new
part,
five
application.
That
would
be
more
useful
for
space,
so
that's
still
still
on
the
table,
but
I
haven't
done
anything
with
that
other
than
look
over.
What
needs
to
be
done.
C
We'd
actually
have
to
have
something
that
we
need
to
apply
for
in
order
to
to
get
that
rolling.
But
that's
that's
something
that
that
that
we'd
like
to
do
and
then
it's
still
the
case
that
libra
space
would,
you
know,
put
forward
their
their
you
design
that
they
had
boards
that
came
back
in
december,
but
I
have
not
heard
a
whole
lot
about
that
in
terms
of
like
the
lab
performance
or
anything.
B
All
right,
okay!
Well,
I
can
give
I'll
give
my
little
the
updates
that
I've
got
here.
One
of
my
homework
assignments
was
to
actually
figure
out
get
in
contact
with
the
antenna
company,
and
I
did
they
evidently
don't
receive
emails
from
me.
So
that's
fine,
but
the
so
they
do
have
a
blade
antenna.
I
posted
in
slack
what
the
price
will
be.
We
can
buy
a
couple
of
them
as
long
as
they're,
not
gonna
as
long
as
they
don't
end
up
sending
it
selling
them
to
somebody
else.
B
First,
it
wasn't
clear
what
that
meant,
but
that
was
their
story
yeah
it
was.
It
was
weird.
It
was
stated
weird
it's
like
they're
available
pending
prior
sale
or
something
so
I
think
I
suspect
the
customer
they're
building.
They
build
these
in
lots
and
I
suspect
the
customer
they're
building.
For
said,
you
know
I
need
x
and
they
probably
have
to
run
it
by
the
customer
one
last
time
before
they
gave
us
any.
B
B
So
my
my
current
task
is
to
get
get
the
2d
dimensions
over
to
up
aerospace
and
see
what
they
think
and
go
from
there
to
see
whether
uub
will
do
the
whole
or,
if
the
aerospace
will
attempt
to
do
the
whole.
The
bottom
line
is
the
antennas
are
like
1500
15.50,
a
piece
I
don't
know.
If
we
want
just
one
I
mean
we
can
buy
one,
maybe
two,
but
that's
kind
of
the
story,
at
least
at
least
it's
there.
B
The
original
antenna
that
up
aerospace
wanted
me
to
look
at
was
it
was
the
same
model
but
a
different
material,
stainless
steel
and
the
person
I
talked
with
on
the
phone
she's
like
we
haven't
built
that
one
in
years.
I
have
to
find
out
about
that
and
she's
like
oh
dear
yeah,
she's
like
if
you
want
to
buy.
If
you
want
to
buy
10
of
them,
that's
great,
I'm
like
no.
We
don't
want
to
buy
10
of
them.
Yeah.
C
B
That's
so
that's
that
at
least
there's
it's
encouraging
that
there's
a
solution
out
there
and
it
looks
like
it's
just
money
and
figuring
out
if
we
can
get
them.
Okay,
so
that's
the
antenna
and
then
I
did
post
some
stuff
about
some
crossover
work.
I
did
on
the
with
the
1276
that
this
semtech
chip,
yeah.
B
Cool,
it's
cool
it
required
to
do
the
like.
The
m17
stuff
requires
a
pretty
fast
processor,
because
you're
you're
doing
48
kilohertz
sample
rates
and
doing
spi.
At
that
rate,
I'm
doing
it
really
brute
force.
So
there's
probably
ways
to
do
it
on
slower
processors,
if
you're
smarter
than
I
am,
but
the
the
cool
thing
is,
I
think,
even
on
the
slower
processors,
you
could
probably
modulate
analog
voice
at
a
lower
sample
rate.
A
B
C
A
C
D
A
E
Yeah,
so
we're
heading
into
our
spring
break.
Our
embedded
systems
class
is
transitioning
out
of
intro
material
into
the
big
projects
and
that's
what
I
baited
alex
and
aniket
with
was,
if
you
work
on
the
ambassad,
that
will
be
your
embedded
systems
project
so
that
now
we're
we're
going
into
that.
I
think
they'll
have
some
more
time
to
be
working
on
stuff.
We
got
some.
E
C
E
I
think
I
think
our
next
step
is
going
to
be
just
changing
the
modulation
parameters
and
demonstrating
that
we
can
receive.
You
know,
keep
keep
the
receive
link
up.
We
were
watching
them
on
the
sdr.
The
last
time
we
were
in
the
lab-
and
that
was
that
was
interesting.
We
got
we
had
a
well
when
you
throw
up
an
sdr,
we
were
starting
to
listen
to
number
stations
and
such
too,
but
that
was
not
relevant
to
the
project.
C
B
There
are
some,
I
guess
it
depends
on
what
kind
of
bandwidth
we're
looking
at
and
maybe
that
maybe
that's
the
direction
to
go
is
like
if
assuming
a
a
leo
satellite,
what
makes
sense
for
spreading
factor
and
bit
rates
and
things
that
you
know,
should
we
be
looking
if
we're
in
the
handband
we
may
not,
we
may
not
want
to
go.
You
know
250
kilohertz
wide.
B
The
only
thing
the
on
the
spreading
factors
and
the
and
the
the
bit
rate
or
symbol
rates.
What's
fun
is
if
you,
if
you
haven't
done
this
already,
is
to
go
to
some
of
the
really
the
like,
go
a
really
wide
spreading
factor
and
then
a
really
slow
data
rate
and
then
watch
that
on
the
sdr
crank
up
the
speed
of
your
sdr
waterfall.
B
C
E
B
Part
of
the
problem
with
the
frequency
offset
yeah,
that's
an
interesting
one.
I
I,
if
you're,
using
like
the
hardware
that
I
sent
you
with
the
those
modules,
don't
have
very
tight
oscillators
on
them
and
if
you
go
down
to
the
really
narrow
bandwidth
you
have
to
manually
tune
each
one
until
it
or
tuned
to
one
of
them
between
a
receiver
or
a
transmitter
or
whichever
side
to
get
them
to
agree.
Because
when
you
get
the
nice
wide
bandwidth,
you
can
be
you.
B
A
B
E
A
C
I
haven't
seen
that
already
published.
I
don't
think
anybody's,
really
looking
too
hard
at
this
or
if
they
are,
they
haven't
shared
it.
It
hasn't
been
put
out
there
in
terms
of
like
an
open
source
publication
and
since
laura
keeps
showing
up
and
keeps
getting
proposed
and
in
some
cases
actually
getting
into
orbit.
In
other
cases,
getting
denied
coordination
or
denied
a
license,
then
it
would
be
a
good
contribution.
E
A
C
F
F
Understanding
like
everything
from
the
very
ground
up,
so
I
haven't
been
able
to
do
much
this
this
week
and
the
last
week
just
because
I've
been
like
trying
to
be
more
involved
with
my
intrinsic
process
and
finding
jobs
and
stuff,
but
I
have
the
spring
break
now.
I
should
be
like
completely
free,
like
sure,
like
few
other
things
and
I'll
be
here
on
campus,
so
and
I
think,
like
our
engineering
building,
like
normally
stays
open
during
those
times
too.
At
least
I
remember
from
last
year,
so
I
can.
F
C
Yeah
dig
right
in
we'll
we'll
do
our
best
to
come
up
with
a
good
problem
statement,
so
that
there's
so
you
can
get
some
traction
completely
understand
what
you
mean
about.
You
know,
there's
a
whole
bunch
of
concepts
here,
just
the
thing
about
bitrate
versus
cymbal
rate
and
and
things
like
spreading
factors
once
you
get
it
kind
of
under
your
fingers,
though
it
will
it'll,
be
okay,
it'll
snap
into
focus,
and
it
won't
take.
C
It
won't
take
much
longer
for
for
you
to
kind
of
get
get
a
get,
a
good
foundation
on
that
and
and
see
where,
where,
where
those
things
you
know
where
they
make
a
difference,
you
know
and
then
like
there's
the
numbers
there's
like
all
of
the
theoretical
stuff,
with
the
with
bitrate
and
symbol
rate
and
spreading
factor
and
all
those
cool
charts
and
then
what
we're
moving
towards
is
okay.
So
how
does
that
then
apply
to
a
particular
environment
and
the
environment?
We're
looking
at
is
somewhat.
C
You
know
leo
with
doppler
moving
around
and
and
through
atmosphere,
and-
and
all
of
that
you
know
is
a
is
a
particular
fairly
high
performance
channel
environment.
So
the
stuff
you're
learning
will
will
smooth
right
into
that
and
then
you'll
see
that
this.
This
is
a
if
you
do
communications
moving
forward.
You'll
see
that
this
is
a
pattern.
You
know
you
you
once
you're,
given
a
frequency
and
a
set
of
modulations
or
other
requirements
and
specifications,
then
you
look
at
the
channel
and
each
channel
is
different
and
you
know
so.
A
C
C
All
right,
so
it
sounds
like
the
action
items
are
come
up
with
some
good
problem
statements
so
that
we
can
get
get
folks,
some
traction
to
consume
the
the
time
that
they
have
so
we'll
do
that
on
slack
or
or
like,
like
dan
said
in
a
shared
document,
but
yeah,
please,
let
me
know
if
there's
anything
that
occurs
to
you,
that's
a
roadblock
or
any
additional
resources.
That's
needed!
