1. A radiolocalization receiver comprising: correlation means for processing a signal from a RF interface, operatively arranged for correlating the signal from the RF interface with a plurality of replica codes, each replica code having a determined code shift and a determined frequency, incoherent integration means, for accumulating a series of coherent integration values into a plurality of incoherent integration memory locations, characterized by data compression means for compressing the content of the incoherent integration memory locations based in part on incoherent integration values previously stored in the incoherent memory locations, comprising magnitude extraction means for extracting the absolute value or the square of the coherent integration values stored in coherent integration memory locations and to generate increment values to be accumulated into the incoherent integration memory locations, wherein the data compression means is configured to subtract a current offset value from the increment values of each coherent integration and to store an accumulated offset of all the offset values subtracted during an incoherent integration operation.
