The invention provides an integrated micro-nano satellite electronic system. The integrated micro-nano satellite electronic system comprises a satellite core electronic unit, a solar wing driving mechanism, a three-axis gyroscope, a three-axis magnetometer, a simulated solar goniometer, a three-axis integrated micro flywheel, a magnetic torquer, a thermistor, a heater, an initiating explosive device, a measurement and control antenna, a GNSS antenna and a data transmission antenna. The satellite core electronic unit is provided with any one or more of the following interfaces: an analog quantity acquisition interface, a motor drive interface, an initiating explosive device driving interface, a heater drive interface, a magnetotorquer drive interface, a CAN bus interface, a high-speed datatransmission interface, and a radio frequency interface. A traditional satellite subsystem type integration mode is replaced, a satellite core electronic unit serves as an information and energy center, components with other functions are matched, satellite composition is simplified, and miniaturization, light weight and high integration design of the micro-nano satellite is facilitated.
