Paper Abstract

The Orbital Express ASTRO spacecraft carried multiple independent sensor systems for estimating relative state in autonomous vehicle proximity operations. The on-orbit performance of pose-estimation imaging and dedicated-target navigation solution methods are compared, for ranges between 150 meters and spacecraft capture. Variations between performance expectations from pre-flight ground tests and actual on-orbit performance are discussed. Analysis results indicate the sources of solution variations.
