Abstract
Remote sensing satellite is important mode of the earth and space observation
and time management system is one of the most important part of remote sensing satellite.Remote sensing satellite is used as the application object.Time system designing and time management method are analyzed
unified time management model is established.Time management operating mechanism is analyzed
and error model which affects time management precision is given
that provides reference for time management system design of remote sensing satellite.The time management model is testified through experiment
and the result shows that the time management method and error model can meet the demand of high precision time synchronism design and analysis.
