*** 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.

* Date 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 it explode. The equipment will fall with parachute.

* Telemetry 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.

* Data: Callsign: CV1LAI (special callsign for the Globosat during these days) Mode: APRS (over AX.25 1200bps) Frequency: 145.030 MHz Power: 1W. Antenna: dipole 1/2 wavelenght in vertical position.
