摘      要：正Traditional Deeply Integrated（DI） algorithms combines the receiver signal tracking loops and the IMU and the navigation filter function into an integrated *** this case,the filter rapidly operates on the receiver-tracking loop I and Q signals which are at a basic level and the IMU measurements to estimate navigation *** this paper,we propose a federated zero-reset（FZR） method for coherent Deeply Integration,where multiple pre-filters are used（one per satellite） at a relatively high data rate working with the I and Q of the correlator *** outputs from these pre-filters are next used in one composite Kalman Filter operations at a relatively low data *** of software simulations are presented which offers significant tracking performance in Low carrier-to-noise and high g environment.
