SUMMARY:Space Navigation with an Omni-Directional Vision Sensor
DESCRIPTION:Lecturer:Omri Kaufman\n Faculty:TASP - Autonomous Systems and R
 obotics\n Institute:Technion – Israel Institute of Technology\n Location
 :Classroom 165\, ground floor\, Library\, Aerospace Eng.\n Zoom: \n Abstra
 ct: \n Details: \n With the onset of autonomous spacecraft formation flyin
 g missions\, the ability of satellites to autonomously navigate relatively
  to other space objects has become essential. To implement relative naviga
 tion\, relative measurements should be taken\, and fused using relative st
 ate estimation. An efficient way to generate such information is by using 
 vision-based measurements. Cameras are passive\, low-energy\, and informat
 ion-rich sensors that do not actively interact with other space object. Ho
 wever\, pointing cameras with a conventional field-of-view to other space 
 objects requires much a-priori initialization data\; in particular\, dedic
 ated attitude maneuvers are needed\, which may interfere with the satellit
 e’s main mission. One way to overcome these difficulties is to use an om
 nidirectional vision sensor\, which has a 360-degree horizontal field of v
 iew.\nIn this presentation\, we will discuss the development of an omnidir
 ectional vision sensor for satellites\, which can be used for relative nav
 igation\, formation flying\, and space situational awareness. The study in
 cludes the development of the measurement equations\, dynamical models\, a
 nd state estimation algorithms\, as well as an experimental investigation 
 conducted at the Distributed Space Systems Lab.
