In this article, we report on the in-orbit experience-an overview of ESTCube-1 operations
from the launch until the experiment, as well as on lessons learned from five years of …

This paper proposes using TRIAD and Unscented Kalman Filter (UKF) algorithms in a
sequential architecture as a part of a small satellite attitude estimation algorithm. This …

Nanosatellites have established their importance in low-Earth orbit (LEO), and it is common
for student teams to build them for educational and technology demonstration purposes. The …

Small satellites use commercial off-the-shelf sensors and actuators for attitude determination
and control (ADC) to reduce the cost. These sensors and actuators are usually not as robust …

Currently, most space missions rely on chemical and electric propulsion systems, both of
which are limited by the propellent tank volume whose “wet mass” is launched from the …

The capability to orient the solar arrays of a spacecraft toward the Sun is an ultimate asset
for any attitude determination and control subsystem (ADCS). This ability should be …

This article presents the development of an anti-windup (AW) compensator architecture for
nanosatellite systems. The design addresses the problem of fault-tolerant control (FTC) for …

SPIN stabilization is the simplest method of stabilizing the attitude of a spacecraft. In the
early era of space exploration, it was widely employed. Today, as the number of micro-and …

This paper presents the in-orbit performance of the ESTCube-1 attitude control system that
used electromagnetic actuators to achieve a high angular velocity. ESTCube-1 is a one-unit …

SNUGLITE (Seoul National University Global navigation satellite system Laboratory
satellITE) is a two-unit cube satellite (CubeSat) with dimensions 10× 10× 23 cm that requires …
