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.
