A Design of a Trajectory Estimator Using Multiple DME Range Measurements.

摘要

This report is directed toward the design of a real-time estimation algorithm, a Kalman filter, that estimates aircraft position and velocity using multiple DME range measurements. The estimator is designed and tested for feasibility as a reference system for examining Inertial Navigational System (INS) low frequency errors. Both a 9-state estimator including jerk states and a 7-state estimator without the jerk states are designed.
