Angewandte Volkswirtschaftslehreportant to consider the source of that data stream to be processed. Since “software” signal processing is stated, it implies an input digital data stream. Thus, the purpose of this chapter is to provide some insight into how the satellite signals propagating through space result in this digital data

Theoretically we could obtain a bit value every ms. However, we deal with noisy and weak signals, so a mean value for 20 ms is computed and truncated to ?1 or 1. One navigation bit durates 20 ms.
