“…• Subsistema de Estrutura e Mecanismos: comporta todos os subsistemas e garante que nenhuma parte do nanosatélite sofra danos que possam resultar no fracasso da missão, assim como protege os componentes eletrônicos contra a radiação ionizante existente em ambiente espacial. [ADDAIM, 2010]. A seleção das cargas úteis para a missão obedece às limitações de três variáveis de projeto que possam ser providas pelo módulo de serviço, sendo elas: Potência elétrica requerida, necessidade de transferência de dados e interfaces mecânicas.…”

“…Before closing this section, it is worth mentioning that there are some older (2000-2010) CubeSat communication systems that had some noticeable features such as the systems described in [79][80][81][82][83][84] which adopted different design approaches both hardware based such as [79] and software based such as [84], however, they are quite outdated for this review. For example, [84] was able to implement both AFSK and GMSK modulation schemes on a DSP connected to a VHF transceiver which had a transmission power consumption of 1 W for a data rate of 1.2 kbps for the AFSK modem and 4.8 kbps for the GMSK modem. The overall features of several such CubeSat communication systems that were developed between 2000 to 2011 are reviewed in [85].…”

“…The AFSK modulation reported in literature is implemented as a CPFSK (Continuous-Phase Frequency Shifting Keying) signal [8], [9]. This signaling has an advantage over the nonmemory FSK scheme because the phase continuity decreases the spectral side-lobe, making the modulation spectrally more efficient.…”

“…For applications in CubeSat TT&C transceiver, the AFSK demodulator is commonly implemented as a non-coherent detector [8], [9]. The main reason for that is the simplicity, considering the AFSK demodulator is on-board of the satellite where there is a strong limitation of resources.…”
