Numerically stable covariance intersection for spacecraft formation flying
The goal of this dissertation is to achieve more numerically stable attitude estimates for distributed systems of spacecraft. The method used is the Covariance Intersection (CI) algorithm, and this research continues and ...
Differential wheel speed sensor integration with GPS/INS for land vehicle navigation
This paper develops an approach for the integration of GPS, inertial measurements from accelerometers and gyros, and differential wheel speed sensors for land vehicle navigation. Incorporating differential wheel speed ...
Micro-arcsecond line-of-sight filtered performance for spacecraft formation flying
Formation Flying is the concept that multiple spacecraft can be arranged in a formation to perform tasks that are not possible with a single spacecraft, or tasks that can be done more efficiently or inexpensively with a ...
