METHOD FOR DETERMINING THE PARAMETERS MEASUREMENT ERRORS MODELS accelerometers for inertial navigation system on measurements of satellite NAVIGATION

摘要

A method of determining parameters of measurement error model accelerometers INS measurements of satellite navigation, comprising measuring the apparent acceleration motion in inertial space of the object produced by accelerometers ANN object in dash inertial coordinate system (vocalization) and sessions navigation determinations of signals systems "Glonass" and GPS, which at timings τ, ν = 1, 2, 3 ... of sessions determined corrective correction to the velocity vector and a vector of coordinates in the navigation path B SK, characterized in that during the movement from a certain moment ti moments τ, ν = 1, 2, ..., l of sessions navigation determinations, where the first point τsovpadaet to t, from the obtained at the next session, the correcting amendment to the vector subtracted speed signals proportional to the product of the gravity gradient on the obtained correction correction, multiplied by the square of the time interval between the moments τi τsosednih sessions from the derived difference as transmission sessions moments τnakaplivayut amount starting from the th same initial moment TPO indications accelerometers ANN accumulate apparent velocities along the axes Piskov until the module of the vector apparent velocity setpoint, at which point tfiksiruyut computing device (BV) of an object components apparent velocity accumulated in the interval [t, t], correcting amendment Δv (t) for the velocity vector related to the time t, becomes the last in the accumulated amount within this range of differences, differences in the amounts worked out for correcting amendment l held in the interval [t, t] Sean
