Abstract
In one implementation, gain measurements for one or more satellite elements may be obtained from one or more calibration stations. A matrix may be generated, with each cell providing a storage for relative gain estimate between an element pair with an associated weight indicating a confidence in the estimate. A pair of elements corresponding to an empty matrix cell and a calibration station with non-zero gain measurements for each of the element pair with non-zero weights indicating confidences in the non-zero gain measurements, may be identified. A relative gain estimate for the element pair may be computed using the non-zero gain measurements for each of the element pair. A weight indicating a confidence in the relative gain estimate may be computed using the non-zero weights. The relative gain estimate may be stored in the cell associated with the element pair and the computed weight may be associated with the cell.
