| Abstract: | The main factors inducing tool errors of the missile rate strap - down inertialguidance are analysed and the mathematical model of the rate strap - down inertial measuring sys-tem is established in this paper. The way to demarcate the rate strap ~ down inertial measuring system by using the globe physical characteristics is also given. In order to compensate the tool errors and to improve the missile guidance accuracy, the error coefficiency of the rate strap -down inertial measuring system is estimated by the method of least square. |
