Abstract
A system for determining the spatial orientation of a movable apparatus includes at least one optical angle-of-arrival (OAOA) sensor array, each of which comprises multiple OAOA sensors arranged to provide a 360° field-of-view (FOV). At least one sensor array is mounted on and has a known spatial relationship to a movable apparatus, the spatial orientation of which is to be determined. Point sources are located at one or more stationary positions within the FOV of at least one of the mounted arrays. An initial-north-finding/initial-vertical-finding (INF/INV) system determines the spatial orientation of at least one of the point sources. Processing circuitry coupled to the INF/INV system and the sensor arrays derives the spatial orientation of the mounted arrays—and thereby the spatial orientation of the apparatus—based on the angular positions of the stationary point sources detected by the mounted arrays.
