*** CV1LAI - Globosat 01 ***
Globosat 01 is the first uruguayan telemetry test from high altitude balloon
of the LAI Project.
CX0CFI (Club Facultad de Ingenieria) invites to the amateur radio community
to participate and report telemetry data.
To be defined. Probably on Thursday 24 of April of 2008 (15:00 UTC aprox.)
* Trajectory and flight plan
The globosat will come out from the department of Durazno (central Uruguay),
what would allow the recovery of the team inside national territory.
The balloon should ascend to a speed of between 200 and 300 meters per
minute, and to arrive until a maximum height of approximately 30.000m (like
reference, the commercial flights go at 10.000m). Arrival that height, the
difference of pressure among the interior and external of the balloon makes
The equipment will fall with parachute.
The platform send telemetry information in standard APRS format in 2m. band.
The APRS message goes encapsulated in a AX.25 (Packet) frames and modulated
in AFSK (1200 bps) FM.
Callsign: CV1LAI (special callsign for the Globosat during these days)
