Rocksanne 2-Alpha is sounding rocket under development whose purpose is to test all new subsystems that will be installed and used permanently in future projects.

The size and power are definitely superior to Rocksanne I-X and the structure is completely composed by carbon fibre and aluminum to be as lightweight and durable as possible. The mission profile is to reach an altitude between 7000 and 10000 meters, exceeding the speed of the sound and testing the resistance of accelerated components up to 10g.

One of the peculiarities of the recovery system of this rocket is the main parachute: a self-guided Rogallo Wing with a total speed of 8 m / s (28.8 km/h) is able to fly the missile back into a predefined landing area, using sophisticated image recognition algorithms, combined with constantly recorded telemetry throughout the flight (IMU and GPS).

ROGALLO WING

The electronic system has been designed and assembled entirely within the association, and will handle real-time recording and transmission of data during launch.

The electronic system consists of a motherboard, which will coordinate all subsystems, each of which is controlled by a series of dedicated daughter-boards.

The firmware on the microprocessors has been developed by our software engineers and it is designed to make the most of the hardware redundancy present onboard.

Deep attention has been paid to the communication system, which involves transmitting and receiving with ad-hoc patch antennas, on different frequencies based on the data type: 868MHz for telemetry, 1.5GHz GPS and real-time video streaming at 5.8GHz. Eventually, data encryption is provided using cryptographic authentication and error correction codes.
