TL;DR: In this paper, the authors highlight the most promising developments reported at the 2017 International Workshop on Micropropulsion and Cubesats (MPCS-2017) by leading world-reputed experts in miniaturized space propulsion systems.
Journal ArticleDOI
The technological and commercial expansion of electric propulsion
Dan R. Lev,Roger M. Myers,Kristina M. Lemmer,Jonathan Kolbeck,Hiroyuki Koizumi,Kurt A. Polzin +5 more
TL;DR: The use of electric propulsion (EP) on satellites for commercial, defense, and space science missions has been increasing in recent decades, from the first successful operation in 1964 aboard the Zond-2 spacecraft to the present day as mentioned in this paper.
Journal ArticleDOI
Development of thrust stand for low impulse measurement from microthrusters
TL;DR: In this article, a data analysis method to reduce the effect of mechanical noise is proposed by introducing an additional term in a fitting function, which is verified that the analysis method used in their experimental conditions reduced variance caused by noise down to one-third that of a normal fitting method.
