Our receiving station for the Stratoballoon project consisted of three major pieces of software:
- SDRSharp (http://www.sdrsharp.com ) – used to pull the signals off of the NooElec SDR receiver.
- dl-fldigi (https://github.com/jamescoxon/dl-fldigi ) – used to translate the radio signals into readable text.
- BalloonMapper (http://tinyurl.com/MarkGilbertSource, "BalloonMapper.zip") – a small application that I wrote to convert the data strings from the capsule into a coordinate on Google Maps.
I’ve gone into great depth about how the first two are configured on my technical blog (“Stratoballoon Radio Details”). Please check out “Balloon Mapper.” on my technical blog for a detailed write-up of the third one.
