YERRA radio status

The YerraLoon project team at the ANU invites radio enthusiasts to help us track flights above the ACT and regional NSW.  Anyone with the right equipment can join the team and upload live telemetry and imagery to the Habhub community tracker.


Upcoming flights

The next YerraLoon flight will be Thursday 24 January 2019. Release will be around 10:00 from Mt Stromlo. The balloon will travel north, landing near Yass.

As a general rule, we prefer to release balloons from Mount Stromlo unless the prevailing wind dictates otherwise. Payload recovery usually occurs around two hours after release. Live updates will be posted on the Mount Stromlo Facebook page and/or on Twitter with the hashtag #YerraLoon.

Flight and chase cars can be viewed on the Habhub community tracker (callsign ‘YERRA’) and live images can be viewed on the Habhub SSDV feed.

Dummy payload

We sometimes locate a dummy balloon payload on Mount Stromlo for the purpose of radio link testing.  Anyone with a UHF sideband receiver or simple software-defined radio dongle can try decoding tracker messages and image packets.  This data can then be uploaded to the ‘Habhub’ community servers via free software.  More information can be found in the UKHAS tracking guide. The balloon’s current position and all active ground stations are shown on Habhub’s public tracker map.

Please only test the Habhub upload for a short while (i.e. not hours and hours), otherwise it dominates the debug log and inconveniences other users.
