Wow!
This was about 3 days ago. The California Near Space Project (CNSP) team launched 4 balloons. Two of them were short-duration, high-altitude flights. The other two were long-duration floaters (K6RPT-11 and K6RPT-12). First, the announcement:

Quote:
Our goal is to reach neutral buoyancy at a very high altitude and fly as far across the United States as possible.
Well...
The balloon not only made it through north america. It completely crossed the Atlantic, entered Spain through Jerez de la Frontera and exited towards Italy. After a 57 hours flight, it eventually descended on the Mediterranean sea off the coast of Algeria.
Look at the green portion of the trajectory after the balloon passed New Jersey. These were quiet hours of uncertainty until the signal was picked up again from the Azores:
Launch time was 2011-12-12 00:40:31z. The last packet was heard on 2011-12-14 09:46:30z:
You can see the full trajectory on aprs.fi while it's recent:
Update: Below is a video of the launch:
Hola, quería saber si el proyecto se podría aplicar a algo diferente, para airsoft. Me explico, sería para localizar a un compañero en el campo de batalla, como ocurre en los videojuegos, tipo modern warfare. Esto se vería reflejado en algo tipo pda donde se le pueda meter un mapa y donde aparezca la escuadra de compañeros y en algo como el google maps se vería dónde esta cada uno.

Hola, podrías aprovechar la red de APRS (144,8 MHz en Europa), pero necesitas una licencia de radioaficionado. También puedes usar las frecuencias libres en 433 MHz (sin licencia), pero tendrías que montarte tú la estación receptora en tierra y alguna aplicación que dibujara las posiciones, p.ej. en un google map.
ReplyDeleteGracias, a ver qué se puede hacer pues.

ReplyDeleteHi guys, my APRS node IW0FKO in Rome Italy contributed to the tracing of K6RPT-11 on my country, and also other digipeater stations in center and south Italy have followed this evolution with interest. I wish you good luck, we will stay to listen on 144.800MHz.
