Optical Navigation System, Phase I

Completed Technology Project

Project Description

Optical Navigation System, Phase I
This proposal is for a flexible navigation system for deep space operations that does not require GPS measurements. The navigation solution is computed using an Unscented Kalman Filter that can accept any combination of range, planet chordwidth, and angle measurements using any ce- lestial object. The UKF employs a full nonlinear dynamical model of the orbit including gravity models and disturbance models. The filter will estimate both states and parameters. The integrated system employs a sensor that uses novel image processing to extract planetary chordwidths. The extra-solar system body sensor will employ band limiting imaging with the band selected to maximize reliable autonomous object identification. More »
