| 요약 | Millisecond pulsars are extremely stable and rapidly rotating neutron stars that emit electromagnetic radiation along their magnetic axes. Due to the misalignment between the rotational and the magnetic axes, the observed pulsar signals are anal |
| 요약 | The autonomous pulsar-based navigation problem is formulated in terms of a nonlinear filtering problem where a single filter is used to estimate the spacecraft position and velocity. The positioning accuracy of a spacecraft traveling at known co |
| 요약 | In order to show the feasibility of pulsar-based navigation, several existing pulsar timing software packages and publicly available radio millisecond pulsar data were used to experimentally verify the concept. An Unscented Kalman Filter was use |
| 요약 | This research also investigated the theoretical frequency stability of pulsar-aided atomic clocks from power spectral densities. Hadamard variance was used to analyze the unfiltered and the filtered clock systems. The result of the analysis show |
| 요약 | The last chapter of this dissertation discusses relative positioning using differential phase measurement. The proposed method can be used to eliminate common mode errors embed- ded in the pulsar measurements when the two observed signal frequen |
