Arizona Near Space Research Presentation

ANSR Arizona Near Space Research is a Phoenix, Arizona based non-profit 501(c)(3) organization that promotes science and education by exploring frontiers in amateur radio and high altitude balloons. These projects cover a wide range of disciplines.  All the designs are released under the GNU General Public License for non-commercial usage.

The helium filled weather balloons reach a typical altitude of 90,000 to over 105,000 feet before bursting.  A parachute allows the payload to fall at a controlled speed to the ground.  The balloons take skyward a variety of small packages that contain a variety of electronics and experiments.  The electronics include APRS (Automatic Position Reporting System), cross-band voice repeaters, and ATV (Amateur Television).  APRS is a digital system that transmits position and altitude from a GPS receiver to a ground station.  A cross band repeater receives voice or data signals on one frequency and simultaneously transmits the same voice or data on a different frequency.  Because the balloon is at high altitude, it allows amateur radio operators to make contact over a long distance.  ATV is used to relay the pictures from a small camera on the payload to a ground receiver much the same way a television station broadcasts its signal.
