Balloon Launch November 13th: Horus 38 – 10:00am ACDT

The Amateur Radio ExperimentersIMG_1767-1024 Group is planning another High Altitude Balloon Launch. Designated Horus 38, it will be an internal project team flight carrying payloads specifically for AREG members. Multiple payloads will be included.

UPDATE: Due to the high wind conditions at the launch site, most of the payloads did not make it off the ground (including the video and SSDV payloads). Currently only the LoRa Cutdown payload is in the air. Chase teams are en-route to recover this payload now.

Flight Track Prediction

The following is the predicted track for the balloon tomorrow. We will be targeting a 5m/s ascent rate, a 30km burst altitude, and 7.5m/s descent rate.

SSDV Experimental Payload – ‘Wenet’

Mark VK5QI and David VK5DGR have been working on a slow scan digital image payload for the balloon system which transmits at 115kbit/s on a new downlink channel. This system makes uses of the UKHAS SSDV server to stitch together images from packets uploaded by multiple receivers. It first flew on Horus 37, and after some refinement will be flown again on this flight. Information on this system is available here.

HD Video Camera Payload

We are also going to fly an upward facing and an outward facing camera, and hope to collect images of the balloon expanding and (hopefully) bursting, as well as some HD video imagery similar to what was achieved back on Horus 12. Thanks to Scott VK5TST and Josh VK5JO for the loan of the GoPro Hero3 cameras for this flight.

RTTY Telemetry

The standard RTTY 70cm telemetry payload will be flying as well. Listen out on 434.650MHz USB, 100 baud  ASCII-7N1. You can get involved through capturing telemetry data and relaying it back to the chase team via the Internet (details on how to setup and operate dl-fldigi are available here:
