Project Horus High altitude balloon project


Repeater Project Horus at Science Alive

Adrian and I got together a few days ago to put together a payload enclosure for his airborne repeater. All told, the enclosure, batteries + antenna weigh in around 800grams.

Adrian's done a great job on the reapter, it works very reliabily and is fully autonomous, including morse ID & automatic beacon mode to assist with finding the payload should something go wrong.

National Science Week
In other news, Project Horus will be making an appearance at Science Alive at the Adelaide showgrounds as part of national science week - we'll have payloads, balloons & tracking equipment on display, as well as a bunch of other toys, robots & gizmo's Adrian's been busy putting together in his time off! If you are free on Saturday or Sunday, do come by!

  1. Hey Terry! it looks great, a little big though. i would say its overengineered, because you havent really posted what the added value of all the new stuff is, apart from the nut board. what to do with it, and whereВґs the project going, still, looks pro.


  2. Hi Tim,
    What you see there is an FM radio simplex repeater. This is used for voice communication essentially this system listens to a radio channel for incoming transmissions. Once it hears the transmission, it records it to memory, then replays it.

    The reason for doing this is that it means you can have communications over a very large range when everybody using the repeater has a line of sight to it with the balloon in the air at 30km, we should be able to have radio communications using hand held radios (walkie talkies) in-car radios over a radius of several hundred km quite easily.

    Were planning to use the repeater for communications between our chase cars and ground stations when the balloon is in the air. :)

  3. Oh geez thats indeed a very good idea. Nice. Still not going for the cellphones on the flights??
