Abstract:

This study was undertaken as part of an investigation of navigation within the solar system by optical means. The objective is to evaluate the suitability of various physical phenomena a sources of navigational information and to estimate the accuracy of navigational information obtained by various techniques. The AMOUNT OF ENERGY RECEIVED FROM THE PLANETS AT VARIOUS WAVELENGTHS IS OF INTEREST IN GUIDANCE. For guidance of space probes at large ranges, the total energy flux is the significant quantity. For physical investigations from probes at small ranges the energy flux per unit area, i.e., the reflectivity or albedo of the planet or of small parts of it, is the determinant quantity. In both cases the spectral distribution of the energy is also significant, e.g., to estimate the amount of energy available in a specified spectral range transmitted by a given filter. Author
