Real-time dynamic integration detection technology of space camera on the ground

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°.
