Universal adaptive control of satellite formation flying [PDF]

open access: yesInternational Journal of Control, 2005
In this paper, a new universal adaptive control scheme for satellite formation flying is developed. The underlying idea of our design is to combine the domination design and the monotone adaptive gain. This scheme is guaranteed to have the properties of position tracking and full adaptivity against all parameters.

Characterization of multi-scale ionospheric irregularities using ground-based and space-based GNSS observations

open access: yesSatellite Navigation, 2021
Ionospheric irregularities can adversely affect the performance of Global Navigation Satellite System (GNSS). However, this opens the possibility of using GNSS as an effective ionospheric remote sensing tool.

Satellite formation flying control by mass exchange [PDF]

open access: yesActa Astronautica, 2014
Abstract Novel approach for formation flying relative motion control is proposed and studied. It is based on a mass exchange between satellites. A certain mass is separated from one satellite in a given direction with a given velocity. It impacts absolutely inelastically another satellite to impart a pulse.
