    Abstract
  • To acquire the Global Navigation Satellite System signal, we design a changed coherent integraltime of the delayfrequency combined acquisition algorithm. While prolonging the coherent time, the FFT points also can be added for equivalence, so the acquisition performance can be improved. The Monte Carlo simulations check the validity of this changed coherent integrationtime acquisition algorithm, and we get the conclusion that the improved performance of this algorithm can be achieved.
