SpaceWire communications in power over Ethernet environment (2022)
Journal Article
Martin, J., & Zaidi, Y. (2023). SpaceWire communications in power over Ethernet environment. CEAS Space Journal, 15, 451–465. https://doi.org/10.1007/s12567-022-00454-z

This is a high-level study into the validation of a unified electric power and communications architecture for modern spacecraft systems. We leverage from blending the European Cooperation for Space Standardisation (ECSS) SpaceWire and the IEEE 802.3... Read More about SpaceWire communications in power over Ethernet environment.

Energy harvesting from landing and taxiing of commercial aircraft (2022)
Journal Article
Brown, E. T. G., & Zaidi, Y. (2022). Energy harvesting from landing and taxiing of commercial aircraft. SAE International Journal of Aerospace, 15(1), 57-74. https://doi.org/10.4271/01-15-01-0004

We demonstrate a virtual proof-of-concept design and experiment for energy harvesting enabling economic and environment-friendly aircraft by recycling forces for power conversion. The harvesting uses piezoelectric materials for extracting energy from... Read More about Energy harvesting from landing and taxiing of commercial aircraft.

Rapid, automated, test, verification and validation for the CubeSats (2019)
Journal Article
Zaidi, Y., Fitz-Coy, N. G., & Van Zyl, R. (2019). Rapid, automated, test, verification and validation for the CubeSats. International Journal of Space Science and Engineering, 5(3), 242-268. https://doi.org/10.1504/IJSPACESE.2019.101412

Bringing up of a small-scale mission assurance and engineering workflow is described. The experiences learned in the ZACUBE-1 mission prompted the development of an automated systems engineering platform leading to conformity in system design, test,...

A GMSK VHF-uplink/UHF-downlink transceiver for the CubeSat missions: Thermo-functional performance (2018)
Journal Article
Zaidi, Y., van Zyl, R. R., & Fitz-Coy, N. G. (2018). A GMSK VHF-uplink/UHF-downlink transceiver for the CubeSat missions: Thermo-functional performance. CEAS Space Journal, 10(3), 453-467. https://doi.org/10.1007/s12567-018-0217-5

© 2018, CEAS. Functional and thermal performance characteristics of a very high frequency/ultra high frequency (VHF/UHF) transceiver based on Gaussian minimum shift keying (GMSK) modulation are presented. The transceiver has been designed for CubeSat... Read More about A GMSK VHF-uplink/UHF-downlink transceiver for the CubeSat missions: Thermo-functional performance.

Functional/thermal verification and validation of an S-band radio for the nanosatellites (2018)
Journal Article
Zaidi, Y., Fitz-Coy, N. G., & van Zyl, R. (2018). Functional/thermal verification and validation of an S-band radio for the nanosatellites. Advances in Space Research, 62(12), 3405-3422. https://doi.org/10.1016/j.asr.2018.04.015

© 2018 COSPAR An S-band radio designed with commercial-grade components for the nanosatellites is functionally and thermally characterized for quiet transmission. The QPSK modulation impairments are minor over −20 °C to +50 °C at 24, 26, 28 and 30 dB... Read More about Functional/thermal verification and validation of an S-band radio for the nanosatellites.

On mixed abstraction, languages and simulation approach to refinement with SystemC AMS (2010)
Journal Article
Zaidi, Y., Grimm, C., & Haase, J. (2010). On mixed abstraction, languages and simulation approach to refinement with SystemC AMS

Executable specifications and simulations are cornerstone to system design flows. Complex mixed signal embedded systems can be specified with SystemC AMS which supports abstraction and extensible models of computation. The language contains semantics...
