摘要：In accordance with embodiments of the invention, a skyward-looking sensorenables classification of points in its hemispherical field of view as either sky, partial skyor not sky, which in turn enables determination from data supplied by the GNSS receiverof whether each satellite in the GNSS antenna's field of view is in a region of sky, partialsky or not sky. Pseudrange and phase data from GNSS satellites determined to be in aregion of sky can be considered reliable and used with confidence in a positioningsolution. Pseudrange and phase data from GNSS satellites determined to be in a regionof partial sky can be considered suspect and can therefore only contribute to a positionsolution with limited confidence and decreased accuracy. Pseudorange and phase datafrom GNSS satellites determined to be in a region of no sky can be considered unreliableand excluded from use in a positioning solution.
