Calculation of Release Region for a Guided Bomb With INS/SPS Based on a Compound Guidance Law

Xue Xiao-zhong

Abstract

According to the working characteristics of guided bomb(GB) with INS/Satellite Positioning System(INS/SPS),a compound guided law based on the virtual seeker algorithm for controlling bomb was proposed. A simplified trajectory calculation model for a certain type of guided bomb with INS/SPS was established,which was deduced reasonably from six-freedom space movement equations.By calculation and simulation,the bomb release region in horizon was got,and factors affecting the boundary of release region were also analyzed.The simulation results confirm the capability of off-boresight launch based on the compound guidance law.The method provides reference for the design and improvement of guided bomb.
