[VK3YT]

Hi,

FYI,

PS-37 is planned to be released at 10am Sun 8/3/2015 from Deniliquin, NSW.
This is an UP/DOWN balloon flight, aiming to achieve high altitude of around 40,000m.

Details:
- LATEX 1600g balloon
- APRS on 145.175Mhz, 30mW, call sign VK3YT-11
- Primary tracker RTTY 100baud, 600Hz shift, 8N1 on 434.650Mhz (Dial 434.649Mhz), 10mW, callsign PS-37, RSID enabled.
- Backup tracker RTTY 100baud, 450Hz shift, 8N1 on 432.220Mhz (Dial ~432,219Mhz), 10mW, callsign PSCD, with CW ID for VK3YT.

APRS tracking on aprs.fi http://aprs.fi/#!mt=roadmap&z=11&call=a%2FVK3YT-11&
RTTY tracking on SNUS http://tracker.habhub.org/?filter=PS-37;PSCD

We will be in #picospace IRC channel on freenode.net on the day.

At high altitude the RF footprint should cover most of VIC and NSW.

Assistance with tracking on the day will be greatly appreciated.
Hope to see you on the map!

Looking good so far. Can't track via radio but keeping an eye on habhub. 26000 meters and still rising, hope you make the 40000 meter mark.

Congrats breaking the 39000 meter barrier

Downloaded the software.
How do I get my location to appear on the Habhub tracker?

UPDATE: Ok it appeared now

Why does the image above have a frequency different to the operational frequency?

I am using 434.649 MHz ??

The recovery trip is as interesting as the flight ... APRS VK3YT-7

[VK5EI]

Well done to Andy and his team. Hope the recovery was also successful.

Going by my calculations the balloon was at a maximum elevation of 4 degs above horizon at my qth. If I deduct the earth curvature, 1 degree for every 111.2Km it puts the elevation at -1.4 degs.

My year 10 mathematics was not a favorite subject so I may be wrong with my calculations

Looking forward for the next flight

[VK3YT]

Thanks everyone for assistance with tracking!

Did you recover it Andy?

Well Done

But a question, have I missed the info - how did you get the photo of the balloons at height please?

Looks like a RC drone camera

The payload got stuck on a tree, I am waiting for a call from the land owner!

That was done on a quad copter drone Rob!

That was done on a quad copter drone Rob!

Did you need CASA approval for the Quad Copter? ( as it appears to be near a Airport.)

Hi,
The photos were taken by another group that came and observed the balloon launch (We had a few interested people came to this launch).
I have no idea what arrangement they had, but will be taking the photos down for now.
Regards,
Andy
