Presentation Synopsis:

“POCKETQUBES AND SMALLER: ONGOING DEVELOPMENT ACTIVITIES AT UNIVERSITY OF LUXEMBOURG”

We present the development of an educational platform based on the PocketQube standard at the School of Military Engineering in Mexico. The project involves the design and implementation of boards that include an onboard computer, sensors, electric power system and communications. All the subsystems are designed and assembled in-house by undergraduate students with specialization in communications and electronics. The activities performed included: schematic design and PCB layout, selection of electronic components, soldering of SMD components as well as firmware development.

During the presentation we will focus on the technical aspects of the OBC board which is constituted by the digital signal controller TMS320F28069 from Texas Instruments. The performance of the board was evaluated with the implementation of an automatic gain controller (AGC) which required processing samples in real-time. An adaptive algorithm was considered to compensate for the attenuation of the processed signal and scale it to the dynamic range handled by the hardware incorporated (ADC and DAC).

These initial steps are considered to be a starting point for future developments with the aim of launching a PocketQube in a near future.
