Andrej,
Thanks. I was digging around the bigredbee website trying to see what all it
takes myself. I don't know what
format the gps coordinates are in but I do know that you can use google maps
and put in coordinates and
come up with a location. Shoot, they probably have an app for that on your
phone. Save buying a handheld
GPS unless you're out so far away from anything a phone is useless.
Michael

Hi
Richard
It's
nice to hear from you again. You are right, the propellant
is plain KNDX. I've also experimented with other sugars
(sorbitol, erythritol and mannitol) but in the end I decided
in favor of dextrose.Bigredbee
GPS was a real game changer at least for me as I don't
have large open spaces to fly from. I fly from a small
clearing in the middle of the dense forest and so far I
haven't lost a rocket yet. BRB GPS is very easy to set
up. First you must download a configuration software from
BRB website. When you connect the GPS to the computer you
can make settings like how often do you want it to report
location and altitude, your call sign, output power, etc. On
the ground you will need some kind of radio setup that can
decode incoming APRS data packets sent from BRB GPS. There
are a lot of options but mostly it comes down to how much
are you willing to spend. Based on my experience I would say
that the best option for rocket use on the field would be
an all-in-one radio such as a Kenwood TH-D72 or a Yaesu
VX-8GR (recently discontinued) or Yaesu FT1DR. These radios
are pricey but very easy to carry around when you are
chasing you rocket as you don't have to have several
pieces connected with cables as would be the case with an
ordinary radio connected to a TNC (terminal node controler
such as Byonics TinyTrak4) and a separate battery. When the
radio receives the data packet from BRB GPS it decodes it
and displays a current altitude, latitude and longitude.
When the rocket lands you take the last known coordinates
and punch them into a handheld GPS receiver or if you have
one of the above mentioned radios it will display a distance
and direction to the landing site.

Hello Sugpro
Amazing work, Andrej...! Your rockets are
beautifully crafted. Congratulations!
I
particularly like your nice flat thrust curve, that's
KNDX, right?
GPS is a
clearly a real boon to rocketry recovery, as your flights
demonstrate. I recently purchased a big red bee
GPS and look forward
to flying it
soon....although I must admit I haven't quite figured
out
how to use it ...
