Recaps
First off, congratulations to Project: Traveler and the Reno County Radio
Amateur Association for putting on a terrific event. Visit their website at:
http://www.rckara.org/project_traveler/gpsl/
You can find a link there to joint the Great Plains Super Launch (GPSL) Yahoo
group. Find out about what happened this year and witness the planning
activities for next year's event.
Next off :-), you each have your own websites to post to but if you want me
to post links to your own recaps send them along and I'll include them below
this notice.
Ok, on to the EOSS recaps:
by Rick von Glahn, NØKKZ
On July 3rd, 2004 at 9:05 am CDT, GPSL 2004 managed to launch 6 balloon
systems. I say systems because one group launched three balloons
attached to one payload train. That was interesting and impressive. If I've
got any of that wrong someone clue me in, please.
EOSS flew a 1200 Kaymont with 12 lbs. of payloads (per the
flight announcement page).
The balloon ascended close to target rates, however it appears that the winds
were substantially lighter than predicted, although they did follow the general
directions indicated at different altitudes.
It was a beautiful clear sky launch. A few clouds up at around 1000 ft that
the balloons penetrated on the way up. These were wisps and the balloons soon
surmounted them.
Mike Manes and I were tracking in my vehicle. He was using two laptops, tnc,
pk80 (I think), and gps receiver to drive APRS+SA and Street Atlas. I was
monitoring using a Kenwood D700 which was in APRS mode giving me range and
bearing to the balloon.
We were 3rd to our touchdown site. Two DF trackers beat
us buy perhaps 30 seconds to the "parking spot" beside the touchdown location.
We probably arrived on scene at around 1 to 3 minutes after touchdown. We (Mike
and I) were anticipating seeing the payload descend to touchdown but that didn't
happen. There were some trees along the road side and between fields which
prevented that. Most likely, in Colorado, we would have been able to spot the
parachute and payload train prior to touchdown.
The payloads landed approximately 3/10th of a mile to the east of Hillside
Rd. and perhaps 5/10ths north of 1st street. This is east of Newton, KS which is
north of Wichita. The payloads came down in a corn field with healthy stalks
approximately 5 plus feet tall. The payloads were invisible from the road. The
corn field was VERY MUDDY.
Mike (primarily) and I obtained permission to enter Mr. Claaussen's property and radioed
back to the recovery crew to go get it. And, they did. It took a while because
while their RDF stuff was indicating one location a beaconing APRS package was
indicating another. After a failed initial penetration to the GPS location, the
RDF guys decided they would follow their RF tracking. This led them directly to the
payloads. Discovery was dependent on being within several yards of the payloads
as optical discovery was hampered by all that closely growing corn. The ground
was MUDDY, very MUDDY.

The official recap will provide a full list of names, but the EOSS guys who
slogged through the mud were, Chris Krengel KBØYRZ and Benjie Campbell WØCBH.
Also searching the field were Marcia DeBell KCØSOW and Larry Noble NØNDM. They stuck to
the tree lines (trees separated different areas of the fields) to keep from
disappearing in the muck but were way out there with the others. Joining them
was Harry KC5TRB from ORB
(pictured above).
Bill Brown WB8ELK flew a system and his balloon touched down approximately 2
miles NE of us.
I wasn't watching a group track of all the balloons but Marty Griffin WAØGEH
said that they all were following the same basic trajectory separated by about a
5 mile circle. I'll probably learn more about that via other reports filed on
the GPSL email reflector.
OK, timewarp to back to Friday and a lite recap of GPSL's symposium.
The presentations went very well. And, we had LOTS of people. An absolute
minimum of 25. I'll have to count them up in the group shots to get an
accurate accounting.
The "hall" was fantastic. It was a lecture hall. Rows of tables permanently
installed on "stadium style" seating. Each row moving from front to back was
raised higher the the nearer row to give an excellent view of the activities.
They had a 20 FOOT screen with a kicker LCD projector. A wild presentation
system including one of those Overhead gizmos that has a camera pointing down to
a surface you can write notes or drawings on, there were various other
presentation tools. The tables were permanently installed because they had AC
and Net connections at each seat. Well, it was very nice to say the least. Best
I've seen yet.
Parking was perhaps 200 feet from the table top you sat at so needless to
say, bringing in and setting up the "show and tell" was a snap.
We even dragged the entire gang out to look at one of EOSS's trackers
vehicles (Chris Krengel's tracker). He has a pretty impressive setup and that was well received. Getting
from the auditorium to the car was the matter of a minute's walk (that 200 foot
thing).
Well, I'm sure lots of others will write stuff and post it in various
locations but I thought folks would like to hear how it went.

Hi all. What a great weekend.
I and my loyal driver had a great time. I even got to walk in a very muddy
Kansas cornfield in my stocking feet, what fun.
We met a great bunch of new people and had a very good time doing so. We
attended all of the presentations at the Hutchinson Community College and had
great food at the dinners and lunchs.
The Cosmodrome is a great place. I really enjoyed reading the displays and
even got to chase Larry, N0NDM from one room to another. HE was moving rather
slow, but he read all of the displays. All!...... Now he is an expert about
space. I also was able to give my Rocket Engine speech, where I discussed the
definition of what an engine is, and how they are classified.
The Saturday balloon flight for EOSS went off well. We had some trouble
during the launch with a connector for the atv module, but the gps module and
the beacons worked well.
The recovery went well, even with the mud.
The lunch after was good, and the trip back to Hutchinson was short. Wish
we could end up flying that short of a distance out here in the wilds of
Colorado.
The scenery was fantastic, as well as all the rain storms we saw and drove
in. It was nice to be in real air again, with lots of humidity and water. I
have missed living at a lower altitude where the air is air, and you can
actually feel the humidity.
I won't stay at the hotel we stayed at again. Hutch is a great place, it
has a lot of really nice homes, and has a lot to offer with tourista stuff.
I want to thank all of the hosting people who made this trip a lot of fun
for Marcia and myself.
