远程导引脉冲变轨方案的有限推力修正

对远程导引脉冲变轨方案的有限推力修正进行了研究。将多脉冲变轨方案设计结果转换为有限推力式并进行修正,以消除转换误差和摄动模型误差。分析了由转换算法和摄动模型产生的初值误差,比较了不同工况下的修正效果。算例表明:将初始多脉冲变轨方案转换为有限推力后进行修正,所得结果能实现真实飞行环境中追踪航天器对目标航天器的拦截或交会。

Correction for Impulse Orbital Transfer Scheme of Long-Distance Guidance Using Finite Thrust

The correction for impulse orbital transfer scheme of corrected The design res converting ult of impulse transfer error and perturbation and perturbation was analyzed, and the correction re calculation results showed that when the initial impu correct, the corrected result could under real flight conditions. tracmg scheme long distance guidance was converted to finite using fini}e thrust was thrust scheme and then The initial error brought by converting algorithm sults were compared under different conditions. The sample lse transfer scheme was converted to finite thrust scheme to spacecraft＇s interception or rendezvous with target spacecraft
