B.E.E.P. missions Primary: Temperature and pressure measurements; Specific: Photography and transmission them with realtime error correction; Comeback mission.

B.E.E.P. Design: payload and control

B.E.E.P. Design: actuation and power source

Central controller system MEMS IMU Absolute barometer for altimeter GPS receiver High computational performance 5 external serial ports, ethernet port Features

Mission algorithm Actions after release: Waiting for parachute opening. When barometric altitude is lower than it’s maximum for 10 meters; Starts telemetry recording and photography; Starts data transmitting process; Waits 2 seconds for flight stabilization; Checks GPS signal reacquiring; Stars return mission control; Stops control, telemetry and photographs recording after 10 seconds of constant barometric altitude. Keeps transmitting gained data till the last written file.
