Oh, one other question: I'm scheduling the speakers for the GPSL
conference Fri 13 Jun, and recall that you have a presentation to
give. You'd be joined by Bill Brown, Ralph Wallio, Mike Grey and
myself (+ perhaps 1 more EOSS presentation). Do you have a preferred

Thanks for the info on the AV equipment. I'll be sure to bring a VHS tape
as well.

Here is the information on the equipment we will bring.

Should we bring our own Lithium batteries or will you have some available?
I need 1 (one) for the Beacon and 3 (three) for the cross band repeater.
If we need to bring them, I'll have to ship them via UPS ground ahead of
time. The airlines won't let you fly with them and I'm not going to take
a chance if one of them decided to "vent" during the flight.

1. 1400'/min descent at 5000' MSL with "heavy" 12 pound load

2. Cross Band Repeater (3 pounds), Redundant Beacon (1 pound),
cutdown/antennas (0.5 pounds), 7.5 pounds for student payload

3. KD7LMO-11

4. APRS on 445.950 MHz

Cross Band Repeater uplink 145.560MHz / PL 162.2
downlink 445.525 MHz

5. 445.950 MHz time slotted as follows in GPS seconds:

00, 30 Micro Beacon

10, 20, 40, 50 Cross Band repater when repeater not keyed up

15, 45 Landing prediction based on in-flight wind data collection
(After burst. SSID set to -0)

Lots of packets, but tracking and recovery likes to know where
everything is.

The cross band repeater is open for anyone to use for tracking and
recovery or general contact. It can also be set to link with the EOSS
cross band repeater in flight. So we will finally get our EBBE link.

Re: GPSL A/V & i'net?

Mike Manes <manes@...>
 

Hi Paul,

Thanks for the info. A few more questions:

1. Were you planning on flying all 3 beacons on your flight string?
If so, then could you put the TT3 w/ plain text hhmmss and alt format
on KPC-3 on 445.975 as KD4STH-11? Your time slot would be 20 sec after
the GPS minute. We will have an I-gate station committed to the GPSL
beacons on that freq.

2. How much do your beacons weigh, and which will you be flying?
We want to reserve as much weight budget under the 12 lb limit for
SpaceGrant balloonsats as possible.

3. If you wish, Jim K0JLZ has invited you to join him as navigator on
the T&R crew. Jim has both APRS and doppler DF in his SUV.

4. Although 144.39 is a sure way to get yourself gated onto the I'net,
that freq is terribly crowded out here near Denver -- you may have a
hard time avoiding collisions. EOSS normally uses 144.34 or 147.555
for our 2m beacons. Our I-gate can also gate beacons from one of
those freqs.

Hi Bill,

Great to hear from you, and thanks for talking up GPSL! BTW, some of
the EOSS trackers will be at Dayton as well: Benji W0CBH, Ben KB0UBZ,
Larry N0NDM, Ann KA0ZFI and Chris KB0YRZ. Say hi (.... ..) to 'em
if you cross paths.

Quickie info: GPSL conference will be held Fri 13 June in the Eng'g
Bld'g on the Colo Univ campus in Boulder, CO. Dinner venues for
Thur and Fri PM have been arranged.

The flights will go from the HS field at the SE end of Deer Trail CO,
about 50 mi E of Denver on I-70, on Sat 14 June at 0900 -- we'll be
setting up there at 0700 MDST.

Details & directions are at: gpsl.eoss.org.

These flights will be carrying up small "balloonsat" payloads prepared
by NASA Space Grant College attendees at the concurrent Workshop
sponsored by Colo Space Grant College at CU. At least four separate
balloons will be launched, tracked and recovered by GPSL teams: EOSS,
ANSR and TVNSP, also joined by the MT State SGC balloon team.

See: spacegrant.colorado.edu&#92;studentsat

Thanks for your support, and I look forward to seeing you in Boulder!

BTW, consider joining the GPSL yahoogroups email reflector to get the

1. 1400'/min descent at 5000' MSL with "heavy" 12 pound load

2. Cross Band Repeater (3 pounds), Redundant Beacon (1 pound),
cutdown/antennas (0.5 pounds), 7.5 pounds for payload

3. KD7LMO-11

CU SGC Workshop / GPSL 2003 Flight 14 June

Mike Manes <manes@...>
 

Hi Bill,

Chris Koehler may already have told you that EOSS will be the "prime
contractor" for the Workshop balloon flight on Sat 14 June from Deer
Trail. As with last year's Workshop, EOSS will arrange for launch
site access and will handle all FAA prelaunch notices and enroute
position reports. In addition, EOSS plans on delivering both the
Helium and enough 1200 gm Kaymont or Kaysam latex balloons to the
launch site for all the flights. So all you need to bring is your
APRS tracking beacon, parachute, flight string, fill rig and mobile
tracking & recovery rig. CU SGC has agreed to pay for the balloons
and gas used to carry the Workshop balloonsats.

This year, EOSS is also sponsoring the Great Plains Super Launch,
an annual event initiated 2 years ago by Paul Verhage, which is
an annual convocation of several amateur balloon groups in the US.
Last year, six groups launched their balloons simulataneously from
an airport near Manhattan KS and effected recovery of all payloads.
Quite a spectacle!

GPSL 2003 is being held in the Denver area and in conjuction with the
CU SGC BalloonSat Workshop. GPSL attendees from Arizona Near Space
Research (ANSR) and Treasure Valley (ID) Near Space Project (TVNSP)
have agreed to join you and EOSS in providing launch, tracking and
recovery support for the 4 (or 5) balloon payload strings to be launched
that morning. All of these strings will carry no more than 12 lb of
payload weight in order to stay FAR 101.1(a)(4) exempt. For this
purpose, payload weight includes everything except the parachute,
balloon and commandable cutdown devices.

Now in order to arrange for FAA forecasting/enroute reports and for
payload string weight planning, I will need to know some details about
your 'chute and tracking beacon(s), which is presumed be GPS driven
and downlinks APRS-compatible 1200-baud UI packets on 2m or 70cm:

1. Parachute diameter or MSL terminal descent rate w/ 12# load.
2. Beacon weight in flight configuration. (this deducts from the
allowable balloonsat load)
3. Beacon callsign and SSID (-11 preferred).
4. Which bands / freqs can you downlink on?
5. Can your beacon transmissions be time-slotted to a particular second
after the top of each GPS minute? (Provides for freq sharing w/
other beacons).

For ANSR and TVNSP: <<I need the same info from you as well!>>

If all balloons are filled for the same excess gross lift, launch
simultaneously and are similarly loaded, then it is reasonable
that they will ascend above FL600 close enough together to allow all
of them to be reported to the FAA as a single "formation" flight -
a far simpler process than separate reports. It is probably
optimistic to expect that all will burst and descend as a formation,
but by that time, they should be well outside DIA's approach and
departure corridors, so position reports need not be a frequent.

There will also be a GPSL conference held on Friday the 13th at CU,
courtesy Chris Koehler. This does conflict with the Workshop
sessions, but if some of your team wishes to meet the GPSL attendees,
including Bill Brown and Ralph Wallio et al, they will be warmly
welcomed!

You are strongly encouraged to join the GPSL yahoogroups email
reflector to stay abreast of developing details which may affect
your flight operations on the 14th. There is a direct link to
joining GPSL@... right on the EOSS web site:

www.eoss.org.

There's also a GPSL web page there that covers the whole
conference.

I look forward to your earliest convenient response, and don't
hesistate to pose any questions that may pop up.

I'm trying for two launches and I think they will be close to identical

Descent around 1200 f/m (assuming the cutdowns are attached
above the parachute this time, and not below them).

I think I can keep the weights to 9 lb.

Callsigns will be KD4STH-9,10,11 (I'll have one 440 beacon for fox
hunting).

I'll stick with 144.390 for APRS. The 440 beacon I have yet to
select.

I can time slot.

I'm not sure what my schedule is going to be for this summer. My wife is a
teacher and doesn't yet know if she's going to get a contract to teach next
fall. She may be starting a new job this summer and that would pretty well
limit much of our summer travels.

It may be more of a possibility to meet somewhere in eastern Kansas - I have
an uncle in the KC area that we could stay with if we were to launch from
that area.

If you'd like to come to Omaha for a day or two, we can fly from
here on Friday, Saturday, or Sunday. I'm not sure if I can head
to Kansas at that time or not - that will be less than three
weeks before the baby is due. Both of my launch sites are
completely outdoors, so we wouldn't be as protected from the
wind.

We can arrange helium transport for whoever shows up. $70 per
T-tank (plus a rental charge if they have one).
Zack, can you make it up to Nebraska just after the 4th of July?
How about during a weekday?

I suppose I could stop in Nebraska on my way to Kansas for a
flight (and not just after visiting Kansas). Mark, what I would like to
do is bring a capsule to fly and just tether it to yours. I'll split the
cost of helium and the balloon. Perhaps we ought to try for an
altitude record.
