N2 - In the error study of inertial navigation system (INS), the research on error analysis which is caused by gyro drift is limited to the constant drift in the past. Anyway, reality gyro drift is not a long-term unchanging one but varies continuously with time. With the study of systematic errors in depth, we can see that there exists a slope drift in a particular fiber optic gyroscope drift simulation, which may cause serious heading and position errors in the Inertial Navigation System (INS), therefore the research closer to the real situation of the system error model is particularly important. This article, based on mathematical model of gyro constant drift affecting system error, establishes slope drift's mathematical model, and analyses systematic errors caused by gyro drift under the static base by the simulation, and explains the simulation results according to the error model. It makes the research of error analysis in INS more comprehensive, and lays a foundation of further study on dynamic error.
