This paper presents the mission analysis, requirements, system design, level test results, as well mass and power budgets of a 1-unit CubeSat ESTCube-1 built to perform first in-orbit demonstration electric solar wind sail (E-sail) technology.The E-sail is propellantless propulsion concept that uses thin charged electrostatic tethers for turning momentum flux natural plasma stream, such wind, into spacecraft propulsion.ESTCube-1 will deploy charge 10 m long tether measure changes in...
In this article, we report on the in-orbit experience - an overview of ESTCube-1 operations from launch until experiment, as well lessons learned five years development and almost two operations. Lessons are identified point view system engineering, electrical mechanical software testing measurements, payload, management. Detailed flight results will be provided in dedicated articles. We hope that other teams can benefit our experience.
This paper presents the characterization and in-orbit validation of ESTCube-1 attitude determination system (ADS). is a one-unit CubeSat built by students launched on May 7, 2013, to Sun-synchronous, 700-km, polar low Earth orbit. Its primary mission centrifugally deploy tether as part first demonstration electric solar wind sail (i.e., E-sail) technology. The ADS uses magnetometers, gyroscopic sensors, Sun an unscented Kalman filter for determination. Here performance commercial...
This paper presents the design, development, and pre-launch characterization of ESTCube-1 Attitude Determination Control System (ADCS).The design driver for ADCS has been mission requirement to spin up satellite 360 deg•s -1 with controlled orientation axis acquire angular velocity attitude during scientific experiment.ESTCube-1 is a one-unit CubeSat launched on 7 May 2013, 2:06 UTC board Vega VV02 rocket.Its primary measure Coulomb drag force exerted by natural plasma stream charged tether...
