SUMMARY:Guidance for Rendezvous and Docking with Tumbling Space Targets
DESCRIPTION:Lecturer:Jérémie Lejzerowicz\n Faculty:Department of Aerospac

 Abstract: \n Details: \n This research focuses on a particular case of dis
 tributed space systems technology: spacecraft rendezvous missions. More sp
 ecifically\, the case of a two-phase satellite rendezvous maneuver is exam
 ined for rigid bodies instead of point-masses. Traditional Clohessy-Wiltsh
 ire models for relative motion become invalid when the spacecraft shapes a
 re considered. The studied mission is considered non-cooperative\, in the 
 sense that the target spacecraft does not maneuver to facilitate rendezvou
 s with the chaser spacecraft.\nThe first part of this research considers a
  new guidance law for rendezvous based on the well-known Proportional Navi
 gation guidance law\, modified for the studied mission type. The required 
 commanded accelerations are presented in the line-of-sight reference frame
  (transverse and longitudinal components). Equations for the relative moti
 on between the target and the chaser are derived. The second part of this 
 research discusses the estimation of the line-of-sight rate and its higher
 -order derivatives in the case of imperfect information due to measurement
  errors. Different filters are implemented\, and a performance evaluation 
 is presented.
