Research of software re-injection technology for aerospace camera controller in-orbit

For the factors of increased of tasks, enhancements of functions and improvement of integrity and complexity in aerospace camera, application system has raised high and long-term in-orbit autonomy and reliability requirements on camera controller. Based on an actual project application background, this paper has put forward a design method of new high reliability aerospace camera controller in-orbit software reinjection instruction sequence which use TSC695F as kernel CPU and process flow of bootstrap receive, cache, checkout and storage update data. Finally, combined with specific test module for camera controller software re-injection, the validity of the software re-injection method raised here has been verified. Still here gives out reference codes of update data package which generated by the ground.
