【Abstract】 Based on system structures and principles of some space cameras,an integration dynamic detection method is proposed to operate space cameras in long-term and reliability on the orbit.A space camera testing unit is proposed,which is composed of own multi-simulated testing apparatus,such as SATL load control,dynamic image generator,space camera controller,CCD imaging system,encoder system,thermal control system,power control system and image data displaying and recording system.These apparatus are synchronized accurately using a SATL synchronous clock and a clock sampling device.Using a simulated integration detection control server as the core,a integration operation model,integration testing method and a working platform based on web dynamic integration are built.The integration detection technology is verified by an example of camera drift angle dynamic adjustment experiment in a movement speed of 0.06(°)/s and obtained imaging max lean is less than 0.01°.更多还原
