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.
