Linear covariance analysis of atmospheric entry for sample return mission
Linear covariance analysis is an uncertainty analysis tool comparable to Monte Carlo analysis; both provide similar statistical information about the performance and uncertainties of a dynamic system. Linear covariance analysis linearizes the models of a dynamic system and propagates the state …

Guidance laws for partially-observable UAV interception based on linear covariance analysis
… target's relative position and velocity. Using Linear Covariance Analysis, an novel algorithm is developed to pick the series of maneuvers that gives the best probability of capture. This algorithm is demonstrated on a quadrotor in flight intercepting a simulated evader drone, and it is shown to …

Linear covariance analysis trade study of autonomous navigation schemes for cislunar missions
… problem of autonomous navigation by conducting a linear covariance analysis trade study on various configurations of autonomous sensors for a representative cislunar mission. The sensor suite is comprised of twelve sensors of varying measurement types and levels of flight readiness: MIMU IMU, …

An application of linear covariance analysis to the design of responsive near-rendezvous missions
… raising, and near-rendezvous operations. An analysis method known as Linear Covariance analysis is introduced to provide a platform of estimating the navigation covariance and dispersion of the spacecraft during the second and third phases, while the first phase, up to main-engine-cutoff, is …

Optimal trajectory design under uncertainty
… design. This thesis explores the use of linear covariance analysis to directly include trajectory robustness in the design process. The covariance matrix can be propagated along a trajectory to provide the expected errors about the nominal trajectory in the presence of uncertainties. …

Autonomous optical navigation for lunar missions
… optical lunar navigation are analyzed using linear covariance analysis methods. The measurements include a feature tracking camera measurement, star landmark elevation measurement, star horizon elevation measurement, and star occultation measurement. Based on trade studies performed, the star …
