Taking initial aiming error as inertial small perturbance, we established a model of guidance loop with velocity pursuit guidance law at the ideal conditions and deduced an analytical expression.

Aiming at the error in intense hypsography terrain area statistic, the paper puts forward an improved statistic method for intense hypsography terrain, and introduces their application fields.

Aiming at these problems, this paper studies how the original error affects the accuracy, works out its allowable values, and finds out the equation between friction of pins and clamping force.
