Estimating geolocation of a user terminal
Abstract:
A system and method for estimating a geolocation The method includes subdividing the camping cell into grid points where each grid point of the grid points has an associated relative offset from a camping beam center; illuminating the camping cell with a camping beam and each of the adjacent cells with adjacent beams; receiving a camping beam signal strength and adjacent beams signal strengths for each grid point of the grid points; profiling, at each grid point of the grid points, ratios of the camping beam signal strength to each one of the adjacent beams signal strengths; mapping the ratios and the associated relative offset of each grid point of the grid points; and estimating a relative geolocation of a User Terminal (UT) from the camping beam center based on a UT camping beam signal strength and UT adjacent beams signal strengths.
