Autonomous navigation for spacecraft is not possible using two-way tracking today, but it is crucial during critical event such as when a spacecraft inserts into orbit around a planet in deep space exploration. As the Deep Space Atomic Clock (DSAC) diminishes in size and increases in stability, the accuracies of one-way radiometric observations are improved and can reach the demands of onboard one-way...
The Fisher information matrix is applied to evaluate the performance of three different navigation methods for the constellation around the libration points. Where the X-ray pulsar relative navigation is the main method, and the starlight Doppler relative navigation and the intersatellite links are integrated with it respectively. Their measurement quantities are respectively the time difference of...
Acoustic propagation delay has not been investigated for a continuous wave multistatic sonar tracking system except for the recent study conducted by Jauffret et al. [4], which estimates the trajectory of a constant velocity target. The results showed that the estimate bias caused by the propagation delay is not negligible, especially for a bistatic system. This paper develops an interacting multiple...
In order to improve the multi-target tracking performance of Doppler radar in the presence of Doppler blind zone (DBZ), the detection probability model with minimum detectable velocity (MDV) is incorporated into Gaussian mixture cardinality balanced multi-target multi-Bernoulli (GM-CBMeMBer) filter. After integrating the new detection probability model into the multi-target posterior density of the...
