SatNOGS rotator tracking a high altitude balloon

Since the conception of the SatNOGS one of our design mantras was modularity, not only we believe that the SatNOGS stack should be able use a wide variety of components but also that components should be able to used in a wide variety of applications.

This Sunday May 1oth 2015 the SatNOGS team had the chance to test how versatile our SatNOGS rotator and control software was by tracking the Aeolus-2way High Altitude Balloon.

Tracking was made possible by receiving APRS data from the Aeolus-2way High Altitude Balloon and converting them using a specialized script as azimuth and elevation coordinates.

The Aeolus-2way is a high altitude balloon build by an awesome team of radio amateur high altitude balloon enthusiasts from Greece, and the help of several groups and organizations.

The balloon launched from the center of the Peloponisos peninsula of Greece in the city of Megalopolis at Plaka airstrip at around 11:10.

The SatNOGS team was positioned 35 km (~21.7 miles) West – NorthWest of the launch site on the Antenna park near the Ano Dolianna village of Mt Parnon. An inverter was used to power two laptops sever ham radio transceivers and our SatNOGS rotator and provide sufficient power for the team’s needs

The balloon began it’s descent at 34.660 meters and it’s payload was successfully retrieved.

We would like to congratulate and thank all parties involved in this high altitude balloon launch for the great team work and cooperation and especially the Aeolus team for their commitment.
