Innovation is the key to powering space exploration. At JPL, we continually strive to innovate to create the capability to explore our solar system and answer the hard science questions. We’ll explore innovations in earth science, Mars Exploration, outer planet exploration, data science/machine learning, and quantum detectors to enable the next generation of spacecraft and systems.
The performance of pulsar-based navigation for deep space exploration is investigated by considering the deep space DAWN mission. The flight trajectory of the DAWN spacecraft is used in the numerical simulation to mimic a realistic mission scenario. This scenario accounts for clock uncertainty, pulsar timing noise, maneuver execution errors, sequential observation and interruptions between pulsar observations. Although an efficient Extended Kalman Filter (EKF) was implemented for most of the DAWN flight, a particle filte
