Product Information

The frequency resolution is chosen such that the frequency bin size is less than (2/3) × T coh, where T coh is the coherent integration time. In case of a 4 ms integration time, the frequency bin size should be less than or equal to 166.67 Hz. Zumberge, J.; Heflin, M.; Jefferson, D.; Watkins, M.; Webb, F.

For a coherent integration period of T coh ms, a ( T coh× 1000 =) X bit number of NH code bits is selected first. For example, for a coherent integration period of 5 ms, the first 5 bits of NH code, i.e., [−1 −1 −1 −1 −1] can be selected. Also, a long incoming BeiDou signal of ( T coh + 19) ms is required to carry out the FFT-based acquisition. In case of T coh = 5 ms, the acquisition metric will be consisted of 24 ms long incoming signal.Guidotti, A.; Vanelli-Coralli, A.; Conti, M.; Andrenacci, S.; Chatzinotas, S.; Maturo, N.; Evans, B.; Awoseyila, A.; Ugolini, A.; Foggi, T.; et al.
