Abstract

A dual-band (SWIR/visible) optical system operating based on Angles-Only Navigation technology. The SWIR module is optimized for imaging stars. The visible-light sensor is independently optimized for imaging satellites including GPS satellites at night. Preferred embodiment provides continuous high accuracy geo-position solutions day and night (including through the 'midnight hole', when solar-illuminated Low Earth Orbit (LEO) satellites are not available. Applicants have experimentally validated proposed system by imaging LEO satellites during terminator using a 1-inch diameter telescope and GPS satellites at night during midnight hole using a 5-inch telescope.
