Anyone want to double-up on a GPSL flight?

Looks like I'll be solo again this year.  If someone wants to split a balloon/gas, I can provide the rest (trackers, parachute, regulator, rigging, etc).

I will double up with you. I can bring a balloon.

I will launch another balloon with Mike.

TinyTrak3 programming

Michael
 

Hi all,

I'm programming up my TinyTrak3 for GPSL2019.

For a balloon, is it better to use regular APRS encoding or Mic-E? In the TinyTrak programming I see that you can select different MIC-E WIDE-X paths. Anyone have any input?

See you in a month or so!

I only use APRS, I never use MIC-E,

I like regular aprs...if my mapping pgm goes kaput, I can see lat/long in the raw packets...

Hey Gang,

Do we have plans afoot for time slots on APRS for the GPSL launch?

Mike / KD2EAT

Re: Time Slots

Not yet...so far I only know of 2 groups planning to fly... As I get more info on who plans to fly on Saturday, I will start planning time slots...
Looking forward to seeing you in June!

50th Anniversary Lunar Landing Flights

BASE_DePauw
 

Sorry that conflicts prevent us from coming to Pella this June.

However, I want to invite members of the ARHAB community to consider conducting a high balloon flight on July 20 to celebrate the 50th anniversary of man landing on the Moon.  BASE is planning on launching a payload containing about 50 small (30 grams or less) objects submitted by the public and in compliance with the FAR regulations for a trip to near space. Ideally, we will recover and return the objects to their owners after the flight.

I didn’t get the SuperLaunch website updated this week with this link, but you can register your balloon now for GPSL.


We will begin posting time slots soon.

Wanted: Payload recovery team for GPSL

Michael Hojnowski
 

Gang,

I'm intending to reprise a launch of the payload we launched at Cornell a few weeks back.  It features a DTMF triggered secondary payload release (the last one was a little Cornell Big Red Bear) with Parachute and tracker.  We attempted to release it at 90,000 feet but our DTMF decoder didn't quite get the message.  A failsafe dropped the bear from 95,000 feet.  Unfortunately, the Bear got a little waterlogged prior to flight (it was drizzling rain) and fell faster than predicted right into Cayuga lake.  It's sleepin' with the fishes.

I want to make another attempt with a, hopefully, better outcome. Since the dropped payload follows its own trajectory, I would need to have a second team attempt to recover that payload while I chase down the main payload package.  If anyone is free to chase the drop payload, I'd love the help.  It's not going to be especially valuable, just a tracker and some token item on a hand-made parachute, so I won't cry if it goes unrecovered.

If interested, please let me know!

Mike,

When you say a "tracker" can we assume that includes a GPS, APRS processor like a TinyTrack3, a transmitter of some power (we chased a 50 mw transmitter once that was a giant waste of time), and a reasonable antenna and that the package has flown before and/or had a reasonable amount of testing?

Would you consider chasing and recovering the secondary and let another group chase and recovery the main payload?

W5KUB-3 launched from Dayton passing slowly over Long Island at 11:51 AM EDT

Hank Riley
 

I guess it's a pico balloon.  Or it's a perfect floater.  Consistently been doing 30 MPH.  Lined up perfectly for a grand tour of Long Island.  Passed right over Manhattan with laser precision.

Launched earlier this morning from Dayton.

W5KUB also doing live streaming high quality video/audio at W5KUB.com

A nice compact little squad of four pico balloons just passed Nantucket Island.   Traveling with speeds now in excess of 40 MPH.

W5KUB-3 trailing those of the Dayton Amateur Radio Association's trio of W8BI-11, W8BI-12, and W8BI-13.

KUB, BI-12, and BI-13 remarkably close together after the distance traveled so far.

Nick,

The flight will have three identical trackers.  They're all APRS "Peach" trackers, originally designed by Alan Adamson, W7QO, though built by me and some Cornell students.  They're running with 1/4 wave dipole antennas and measured at about 15mw.  I've flown 12 of my own payloads with these trackers, and assisted in a half dozen other flights with them.  I've never lost a flight using these trackers, aside from that last drop payload that ended up in a lake.   That said, they're 15mW.  It takes skill to track and recover them.  It's usually advisable to have someone near the predicted landing zone as it descends.  If they're in a tree, you'll hear them easily a mile away.  If they're on the ground, it could be 1/4 mile or less, depending on terrain.  On one recovery, I had to unsquelch my radio and listen for squawks and driving around doing crude "rdf" until they were loud and clear enough to decode.  I know I'm a whacko, but in my opinion, that adds to the fun and challenge of the payload fox hunt.  Since the payloads belong to me, I can take that chance.  For other groups, we usually supplement with a SPOT or something.

I'd prefer to chase my main payload, since it'll have hundreds of dollars of additional electronics on it.  I wouldn't want to put the "declared lost" responsibility on anyone but myself.  The drop payload I'm requesting help for will just be the stuffed animal with a tracker, which costs me about $50 to build.  If we can't find it, "oh well".  I'll spend more than that on gasoline on the chase day.

Anyway, the payload I'm requesting help for is simply a fun and silly little experiment.  No harm, no foul if lost, or if people aren't interested in chasing it.  I can always backtrack to look for it after my main payload recovery.

Michael:

Just catching up on emails after meeting you at Hamvention.  What kind of tracking device are you going with for the bear?
