Caracteritzation of noise in MEMS accelerometres for femtosats [PDF]

2021 IEEE Aerospace Conference (50100), 2018
The aim of this thesis is to determine the characteristics of the noise of an ultralow noise MEMS accelerometer. The study of these characteristics will allow to determine if the accelerometer can be used in the scientific payload aboard a femtosat. And it the case that it is used, it will allow to calibrate the accelerometer to provide a better signal.

An Analytical Framework for Determining the Minimum Size of Highly Miniaturized Satellites: PlanarSats

Aerospace
This paper introduces a power-driven systems engineering methodology for the early-phase design of highly miniaturized satellites: PlanarSats. We derive an analytical framework linking power requirements, contingency policies, solar-cell performance, and

High Gain Miniaturized MPA with MSS for FemtoSat Communications

2019
A metasurface superstrate structure (MSS) is highly useful for improving the performance of planar antennas and reducing their size due to their unique electromagnetic properties. In this research article, a very small microstrip patch antenna (MPA) with MSS is proposed and analyzed using ANSYS HFSS to operate at 8.20 GHz for ultra small satellites; i ...

FemtoSats in Zero-G ISS Experiment

The FemtoSats in Zero-G investigation was an ISS experiment in which a handheld deployer ejected four purely mechanical FemtoSats within the ISS. Femto Satellites are centimeter-scale spacecraft that weigh less than 100 grams. The FemtoSats and deployer were made on the Additive Manufacturing Facility (AMF) onboard the ISS on August 28th, 2017, and ...
