Thermal Simulation of a CubeSat
2019 IEEE International Conference on Electro Information Technology (EIT), 2019This paper presents a thermal analysis and control framework for a cubesat which can serve as an on-orbit experimental platform on living mammalian tissues. In particular, the Bio-CubeSat will be used to study long term effects of space radiations and microgravity on a living sample of mammalian bone tissue contained in a bio housing. This housing will

Design of Turbo Codes for CubeSats
2021This paper discusses the use of Turbo Codes in CubeSats data transmitters. Data transmitters are used to transmit mission data with an adequate data rate. This is comparable to the cases of bigger satellites. The designs of different turbo coders are modelled while varying the values of the system parameters.

Precise Orbit Determination of CubeSats Using Proposed Observations Weighting Model [PDF]
International Association of Geodesy Symposia, 2022 CubeSats can be used for many space missions and Earth science applications if their orbits can be determined precisely. The Precise Orbit Determination (POD) methods are well developed for large LEO satellites during the last two decades.
