低成本卫星在轨交会对接组合导航系统设计
Integrated Navigation System Design for In-orbit Docking of Low-cost Satellites
摘要
Abstract
A low-cost integrated navigation system for space vehicles based on cooperative objectives is designed and implemented for in-orbit satellite docking mission requirements.A loosely coupled,segmented integrated navigation approach based on the global navigation satellite system(GNSS),inertial navigation system(INS),laser rangefinder,and visual camera is employed,supporting full navigation from far to near.A cubature Kalman filter(CKF)algorithm is used for multisensory data fusion,and an autonomous switching algorithm of segmented integrated navigation mode is proposed,enabling autonomous smooth switching of different navigation modes.The system has the characteristics of low cost,high accuracy,and high availability.The semi-physical simulation results show that the system meets the requirements of in-orbit satellite autonomous rendezvous and docking or in-orbit services.关键词
