Extension of the proximity-quotient control law for low-thrust propulsion [PDF]

, 2008
In this paper, the proximity quotient control law, first developed by Petropoulos, is extended to account for both third body effects and solar radiation pressure based on the mission requirements for a hypothetical NEO deflection mission to the asteroid

Using mission analysis software GMAT to develop skills in astrodynamics

, 2017
Learning about the geometry and kinematics of orbital motion (or 'astrodynamics') is challenging due to its 3D nature. To address this, the University of Bristol have developed 3D orbit visualization exercises using a free NASA tool called 'General ...

Incremental solution of LTMGA transfers transcribed with an advanced shaping approach

, 2010
In the last decade the global optimisation of low-thrust multi-gravity assist transfers (LTMGA) has been tackled with different approaches. Some authors proposed to generate a first guess solution by building a multi-gravity assist transfer with ...

Hohmann spiral transfer with inclination change performed by low-thrust system

, 2013
This paper investigates the Hohmann Spiral Transfer (HST), an orbit transfer method previously developed by the authors incorporating both high and low-thrust propulsion systems, using the low-thrust system to perform an inclination change as well as ...

Extension of earth orbits using low-thrust propulsion

, 2010
The primary motivation for the utilization of space for environmental science, and in-particular Earth Observation, is the unique vantage point which a spacecraft can provide.
