CubeSat evolution: Analyzing CubeSat capabilities for conducting science missions

Progress in Aerospace Sciences, 2017
Abstract Traditionally, the space industry produced large and sophisticated spacecraft handcrafted by large teams of engineers and budgets within the reach of only a few large government-backed institutions. However, over the last decade, the space industry experienced an increased interest towards smaller missions and recent advances in commercial ...

Thermal Simulation of a CubeSat

2019 IEEE International Conference on Electro Information Technology (EIT), 2019
This 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

2021
This 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.

CubeSat Torrent: Torrent like distributed communications for CubeSat satellite clusters

MILCOM 2012 - 2012 IEEE Military Communications Conference, 2012
CubeSat is a pico satellite weighing one kilogram, measuring one liter in volume and is used primarily for space research. Low data rate communication limits the use of CubeSats for missions like imaging and remote sensing. In this paper we study how power, volume and geometry constraints of a CubeSat satellite cripple CubeSat communications and ...

Using deep learning to map retrogressive thaw slumps in the Beiluhe region (Tibetan Plateau) from CubeSat images

, 2020
Retrogressive thaw slumps (RTSs) are among the most dynamic landforms in permafrost areas, and their formation can be attributed to the thawing of ice-rich permafrost.

A Dual-Band Circularly Polarized Shared-Aperture Antenna for 1U CubeSat Applications

IEEE Transactions on Antennas and Propagation, 2022
This communication presents a design of a dual-band circularly polarized antenna with structure reuse for one cubic unit (1U) CubeSat applications. It is a challenging to design an antenna with the limited space of a CubeSat platform.

Preparations for the MicroMAS CubeSat mission

2013 IEEE International Geoscience and Remote Sensing Symposium - IGARSS, 2013
The Micro-sized Microwave Atmospheric Satellite (MicroMAS) is a 3U CubeSat (10×10×34 cm, ~4 kg) hosting a passive microwave spectrometer operating near the 118.75-GHz oxygen absorption line. MicroMAS is a dual-spinning 3U CubeSat that aims to address the need for low-cost, mission-flexible, and rapidly deployable spaceborne sensors.
