SUMMARY:Guest ASRI Seminar - "Pulsar-Based Deep Space Autonomous Navigation
 "
DESCRIPTION:Lecturer:Prof. Jason L. Speyer\n Faculty:Mechanical and Aerospa
 ce Engineering\n Institute:UCLA\n Location:ASRI Seminar Room (room No. 201
 )\n Zoom: \n Abstract: \n Details: \n The performance of pulsar-based navi
 gation for deep space exploration is investigated by considering the deep 
 space DAWN mission. The flight trajectory of the DAWN spacecraft is used i
 n the numerical simulation to mimic a realistic mission scenario. This sce
 nario accounts for clock uncertainty\, pulsar timing noise\, maneuver exec
 ution errors\, sequential observation and interruptions between pulsar obs
 ervations. Although an efficient Extended Kalman Filter (EKF) was implemen
 ted for most of the DAWN flight\, a particle filter was used to reduce the
  large initial position uncertainty in which the integer ambiguity of the 
 number of pulsar wavelengths were resolved. The resulting position and vel
 ocity uncertainty initializes the EKF. In addition to numerical simulation
 s\, an analytical comparison between the measurement noises of X-ray based
  and radio based pulsar timing/navigation systems is discussed.
