Solar sail technology has been proposed and developed for space explorations with
advantages of low launch cost, no-propellant consumption, and continuous thrust, which has …

In this paper, the current state of the art of solar sail technology is reviewed. Solar sail
research is quite broad and multi-disciplinary; this paper focuses mainly on areas such as …

The use of the electrochromic device has been proposed for the attitude control of spacecraft
for decades because its optical characteristics can be altered by electrical excitation. The …

The method of simultaneous relative motion and attitude control by a solar radiation
pressure is proposed. The control goal is to stabilize the given closed relative orbit. The …

In the history of solar sail research, numerous methods have been proposed to control the
spacecraft attitude. Different in detailed operations, almost all of them rely on solar radiation …

Recently, a reflectivity modulation technology was successfully tested in the worldʼs first
solar sail demonstration mission. In the mission, a reflectivity control device was employed to …

This paper demonstrates a detailed analysis of the feasibility for compact formation system
around an L2‐type artificial equilibrium point by means of continuous low‐thrust propulsion …

The paper discusses the problem of maintenance of the tetrahedral configuration of four
satellites. They are assumed to move passively along near-circular orbits and, in linear …

This paper presents a planetary elliptic displaced orbit (PEDO) for a solar sail with reflectivity
control devices (RCDs). The problem of multiple solar sail formation flying in which the …

We analyze a cooperative control framework for electric sail formation flying around a
heliocentric displaced orbit, aiming at observing the polar region of a celestial body. The …
