Radiology of the Pharynx and the Esophagus is to find the random model of burst signals. This paper proposes a probability model of short burst signals based on the Poisson distribution by using the theorem of the binomial distribution to approximate the Poisson distribution, which can simulate the stochastic process of the signals entering

Performance Evaluation of Spaceborne Atomic Clock for BDS-3 Basic Systemseriously restricts the service performance of BDS, and the performance of satellite atomic clock directly determines the accuracy of satellite clock difference. To solve this problem, this paper studies and evaluates the performance of BDS-3 spaceborne atomic clock in detail. Based on the precision

Unification of Multi-GNSS Bias Reference and Parameter Optimization of ISB/IFB Random Modelfect the precision orbit determination or positioning performance. In this paper, the unification method of multi-GNSS bias reference is derived, and the ISB /IFB random model is constructed based on the first-order Gaussian Markov process. The observation equation is solved by the virtual observati
