Astrobiology research with cubesats; Cubesats: Powerful science platforms for space explorations

, 2013
The improvements in the miniaturization of spacecraft and spacecraft subsystems have resulted in a wide variety of small satellites and nanosatellites. This has opened the door to inexpensive, lightweight, small and !exible satellites and missions with various scienti"c applications. One such application could be the use of CubeSats for astrobiological

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 ...

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.

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.

CubeSat Separation Parameter Optimization

2018 12th International Conference on Signal Processing and Communication Systems (ICSPCS), 2018
To implement noninterference deployment and meet the initial orbital attitude requirements of CubeSat, the CubeSat separation process is designed, theoretical analyzed and parameter optimized. Aiming at the direct-driving kinematic scheme of separation spring pushing CubeSat to open the door, the dynamic mathematical model for kinematic coupling system

Miniature Klystron for CubeSats

2020 IEEE 21st International Conference on Vacuum Electronics (IVEC), 2020
We report progress on a miniature klystron amplifier for 1U (10×10×10cm) CubeSats with output power of 32 watts at Ka band (35.6 GHz) and saturated gain of 35 dB. Three beam testers have been built for testing the cathode and focusing structure. A narrow band microwave amplifier is currently under construction and will be discussed.

A Fault-Tolerant MPSoC For CubeSats

2019 IEEE International Symposium on Defect and Fault Tolerance in VLSI and Nanotechnology Systems (DFT), 2019
We present the implementation of a fault-tolerant MP-SoC for very small satellites ( $W$ of total power consumption, which for the first time enables true fault-tolerance for very small spacecraft such as CubeSats. For critical space missions aboard heavier satellites, we implemented an MPSoC-variant for the space-grade XQRKU060 part together with the

Propulsion for CubeSats

Acta Astronautica, 2017
Abstract At present, very few CubeSats have flown in space featuring propulsion systems. Of those that have, the literature is scattered, published in a variety of formats (conference proceedings, contractor websites, technical notes, and journal articles), and often not available for public release.
