Data Processing for Positioning
The output from the tracking loop is the value of the in-phase arm of the tracking block truncated to the values 1 and −1. 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.
