In an embodiment, there is provided a method for determining a spacecraft instantaneous velocity using starlight. The method includes determining, by a star pairing module, a plurality of star pairs in a selected star field image. The selected star field image includes a plurality of star images. The method includes estimating, by a line of sight estimation module, an apparent bearing direction to each star in at least some of the plurality of star pairs; determining, by the line of sight estimation module, a respective apparent inter-star angle for each star pair of the least some star pairs; and estimating, by a velocity estimation module, a spacecraft velocity to within a total velocity error based, at least in part, on the apparent inter-star angles.
