This might be an inspiration to others: In the HAB group at google I found this message :
We started a local project here, in center of our capital city, Budapest:
Try to put on water of Danube a simple, free floating buoy with a telelmetry transmitter.
The main aims are:
- to reuse radiosonde hw with amateur software
- to test a simple, very cheap waterproof box, as cover of the electronics, and a "platform" for another tests.
- try to follow in different way this moving device:
We build "light-weight", mobile RPi2 based receiver
We test our universirie,s based Satellite Control Station, ready to control our small pockecube sat, Smog-1
We try to use the "traditional" receiver setups in car, to follow the buoy: rtty with dl-fldigi and aprs with a mobile iGate
We are in the last tests, play to "put on water" it on Saturday morning, 20 maj.
Basically it is a chellange for us to receive its telemetry, but there are some options to follow it:
DUNA3-12 on aprs.fi
DUNA3 on tracker.habhub.org
Our Satellite Ground Station,s activity is here:
its websdr receiver is here:
To real time control the parabola receiver there is a newly developed small RTTY receiver on RPI2. It receives only the coordinates of the buoy, and upload them to the control server. You can follow this data here:
Based on this data flow you can follow the buoy on the google map here:
And you can follow the received signal on our open webrx system, here:
The project has a small web page, mainly in Hungarian, but with pictures:
Thank you for your attention, best wishes:
