Electronics Department

Our department is composed of young people from the main faculties of the School of Information Engineering of the Polytechnic and the heterogeneity of degree courses of origin is as simple reflection of the breadth of issues that members are facing. The theoretical knowledge gained in Bachelor’s and Master’s courses, together with more practical skills of “problem solving”, has enabled us to participate effectively in the development of critical subsystems such as engine ignition rocket or parachute ejection and release system, or other independent systems as the board that interfaces sensors and the processing unit.

Up to now, the working group called Integrated Project Team Electronic Systems, has been involved in the design of all electronic systems in Rocksanne IX. In this last year of work, all the projects carried out previously have been optimized and the basis for the on-board systems that will equip R-IIX and future stages of Rocksanne Program have been thrown.

Talking about R-IX, the main board, which we called “Yoda Board”, is composed of a circuit designed and assembled by students of the Department which is the platform for connecting the sensors onboard; for this purpose computer unit consists of a main board of ST Microelectronics equipped with an ARM Cortex M4 CPU. A key part of this project is represented by the operating system and the various routines that are running on the processor: thousands of lines of C ++ are the result of detailed work and creativity of some members within the department with the help of two very important external collaborators, that attend a PhD program at our University.

Yoda Board

Engine ignition board

On the missile Rocksanne IX there is only one secondary board : the one that is in charge  of control engine ignition, it is producted thanks to the tested DIY experiences in the field of molding of the circuits.

The manual experience counts so much in our field: in Electronics when we say “homemade” this is  what we mean (in addition to beer, but that’s another story).

The wireless communication’s system on board instead consists primarily of two antennas surrounding the fuselage of the missile at the electronics compartment: one is in charge of reception of the GPS satellite signal, the other allow efficient communication with the ground station sending telemetry.

It appeared a highly innovative system for the low power required for transmission (100 mW) and the omnidirectionality and the quality of the study has been recognized as the work of the member responsible has been published in the proceedings of EuCAP 2014, one of the most important  international conference of the sector, EuCAP 2014.


Wireless communication system

Constructively they are constituted by ‘patch’ of suitable material which adhere to the outer surface of the missile minimizing the aerodynamic impact.

In testing and in flight has so far shown excellent stability, confirming the validity of the project.

Ground Monitor

At the end, the management software intended for the ground station: the Ground Monitor, it represents what our team has provided to colleagues who have dealt with the real-time analysis of the mission.

It is the user-interface with the many details that are generated during the flight and it allows easy interaction with the data and the detection of any anomalies or problems that could occur.

We are already engaged in the project developments as a feasibility study of a system for acquiring and processing images to reconstruct the structure of the missile with the aid of visual references (for the eventual correction of instrumental data), but above all to augment the recognition of the pattern of the soil and thus bring the missile in limited areas even with problems with the GPS and still avoid landing in unwanted areas.

We are always looking for smart guys with whom to share the dream of arriving there where no other Italian student ever arrived!
