In this research,we develop a Zero Velocity Update (ZUPT) based method for astronaut navigation and evaluate its performance under different locomotion patterns.In this ZUPT based dead-reckoning,the position drift of IMU is corrected using the constraint that the instantaneous velocity is zero when static state is automatically detected.A series of field experiments have been performed on terrains of different slopes and hardness in an urban park and a desert under different locomotion patterns,such as walking and hopping.The experimental results show that the positioning accuracy of the developed ZUPT based dead-reckoning is 1.5%-2.3% under different locomotion patterns,demonstrating the potential of ZUPT for astronaut navigation.
