1. 1. Comparison of Control Approaches for Formation Flying of Two Identical Satellites in Low Earth Orbit

   University essay from KTH/Rymdteknik

   Author : Hasan Basaran; [2020]
   Keywords : Aerospace; Chief; Control; Deputy; Feedback Linearization; Follower; Formation Flight; Fuel Consumption; Guidance; Leader; Model Predictive Control; Relative Orbit; Rendezvous; Sliding Mode.;

   Abstract : Formation flying of satellites describes a mission in which a set of satellites arrange their position with respect to one another. In this paper, satellite formation flying guidance and control algorithms are investigated in terms of required velocity increment Delta-v, and tracking error for a Chief/Deputy satellite system.

3. 2. Development of a Low Earth Orbit Mission Preliminary Analysis Tool

   University essay from KTH/Rymdteknik

   Author : Giada Staniscia; [2019]
   Keywords : Mission analysis; CubeSat; Propulsion; Low Earth Orbit LEO ; Perturbations; Atmospheric drag; Earth oblateness.;

   Abstract : The objective of this project is the development of a mission analysis tool for the nanosatellite company GomSpace Sweden. Although there are many existing software, they can be quite complicated and time consuming to use. READ MORE

4. 3. Networked Model Predictive Control for Satellite Formation Flying

   University essay from Luleå tekniska universitet/Rymdteknik

   Author : Damiana Catanoso; [2019]
   Keywords : Satellite Formation Flying; Model Predictive Control;

   Abstract : A novel continuous low-thrust fuel-efficient model predictive control strategy for multi-satellite formations flying in low earth orbit is presented. State prediction relies on a full nonlinear relative motion model, based on quasi-nonsingular relative orbital elements, including earth oblateness effects and, through state augmentation, differential drag.
