© 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.
