“…REMARK 11 (Underweighting Factor) The use of an underweighting factor uw¸0 in (106) is inherited from the NASA Apollo and Shuttle programs [9]. When a filter is first turned on, or after running for a period of time without measurements, the filter gains can be large due to large state uncertainty.…”

A methodology is summarized for designing on-board state estimators in support of spacecraft exploration of small bodies such as asteroids and comets. This paper focuses on an estimation algorithm that incorporates two basic computer-vision measurement types: a landmark table (LMT) and a paired feature table (PFT). Several innovations are developed to incorporate these measurement types into the on-board state estimation algorithm. Simulations are provided to demonstrate the feasibility of the approach.
