Balloon APRS (Automatic Packet Reporting System) is a method of tracking high altitude balloons using amateur radio frequencies and GPS technology. It involves launching a weather balloon equipped with a small radio transmitter, a GPS receiver, and a small computer or microcontroller to transmit the balloon’s location, altitude, and other data back to ground stations via the APRS protocol. This method is often used by amateur radio operators, students, and researchers to track the movement of the balloon, collect atmospheric data and study the upper atmosphere. The balloons can reach altitudes of over 100,000 ft and travel hundreds of miles away from the launch site. The data and images captured by the payload can be used for scientific research and education purposes.
