摘要：
In order to meet the developing requirements of the high-precision GNSS(Global Navigation Satellite System) receiver and spread-spectrum TT&C equipment, we researched high-precision simulating technology of DSSS (Direct Sequence Spread Spectrum)signal and proposed simulating technology of carrier phase and pseudo code phase based on correction technology online. This technology avoids sacrificing implement slice to improve phase precision and can simulate relative motion between receiver and object. In this paper, high-precision generating method of digital middle frequency signal is focused on. The effectiveness of this algorithm has been corroborated by theoretical analysis, simulation and applied to some spaceflight simulator successfully.
