findPreambles-trial.zip - This is GPS Matlab findPreambles finds the first preamble occurrence in the bit stream of
each channel. The preamble is verified by check of the spacing between
preambles [6sec] and parity checking of the first two words in a
subframe. At the same time function returns list of channels, that are in
tracking state and with valid preambles in the nav data stream.
