Saturday, August the 4th, at around 8:00 LT (05:00 UTC) the
YO3KSR team will try to launch a High Altitude Balloon (HALO),
This time, the balloon will have some
scientific experiments on board and the APRS position and telemetry will be sent
on 144.850 MHz in order to give a chance for foreign
radioamateurs to directly receive the beacon.
We will digipeat the beacons
onto 144.800 MHz in order to put Stratospherium II onto the
APRS.FI via local I-Gates.
The launching site coordinates are around Mizil in Buzau County, depending on
last minute flight path simulations: 45.000118,
026.262517(N45░ 0' 0", E026░ 15' 45")
looking around the flight area on www.aprs.fi,
you will see the tracking team following the balloon.
The beacon will be
transmitted into a dedicated antenna (kind of turnstile) with 5 W output power
at every 12 seconds.
The telemetry (via APRS) will include: Main battery
voltage, the payload internal temeperature and the external temeperature.
The payload includes experiments from Romanian scientific community:
-Data logger for relative humidity in stratosphere;
-Pollution grade, UV and magnetic fieldáinduction for various
-Air samples for later analisys;
The recorded data, photos and the movie from the onboard cameras will be
available soon after the flight.
Receiving reports are welcome to email@example.com

Stratospherium I was a great success as we settle a East
European altitude record with 35.000 m a.s.l.
