In this paper a general perturbation theorem about orbital perturbed guidance is derived. By means of the theorem, we can estimate propagation value of the deviation along the orbit which is caused by disturbing force, such as the gravitation, especially aerodynamic force and so on. Then, as examples, we introduce two simple practical applications of the perturbation theorem.

This article covers the advantages of the repeated method and the applications of the repeated method in strap-down inertial system. The differences of this method with those described in the previous articles [1], [2] are:1. Not only the reliability of the system, but also the accuracy of the system will be improved.2. The most key components, which effect the accuracy in guidance, should be repeatedly fit in the optimum directions and those which effect the reliability should be considered to be in the orthogonal or non-orthogonal repeated method.3. This article provides the method of inspecting failure by means of range and derives the formulae of calculating accuracy and ineffectiveness. This method will make calculation simple and work of the system reliable.4. Applying the theory mentioned above, the error in guidance will be decreased by 1/2 and the ineffectiveness can also be decreased by two orders of magnitude, if a longitudinal accelerater and a two-freedom gyro are added to the strap-down guidance device.

Finally, an example on applying the second order perturbed guidance theory for all-way guidance is given.
