Technique for Spacecraft Orientation based on Measuring Spatial Variations in the Power Spectral Density of the Cosmic Microwave Background

We suggest a new orientation technique based on measuring spatial variations in the power spectral density of the cosmic microwave background. The technique uses experimentally detected dipole anisotropy of the cosmic microwave background, leading to the radiation temperature being a function of the spatial direction. We estimate the error demonstrated by our technique as applied to solving spacecraft navigation and orientation problems
