For the factors of increased of tasks, enhancements of function 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, a method of new high reliability aerospace camera controller in-orbit software re-injection instruction sequence and process flow of bootstrap receive, cache, checkout and storage firing data are put forward by taking TSC695F as kernel CPU. Finally, combined with camera controller software re-injection specific detect module, the validity of the software re-injection method raised here has been verified. Moreover, reference codes of ground generation top pouring data package are given.
