    The paper summarises experience from development of on-board software for three scientific space instruments.Two alternative development philosophies were consid-ered.The obvious approach is to focus on the scientific functions of the instrument, and then interface the pro-gram to the "hardware" by ad hoc means.An alternative approach was suggested by our experience on industrial applications: considering the software from the real-time point of view.This approach was selected.The paper describes central issues of space instrument software development in the framework of real-time pro-gramming.We generalise the real-time approach to cover all issues related with the environment: timing of software functions' execution, support for the project life cycle, and the instrument autonomy concept.We highlight the im-portance of real time kernel and its extensions as the ve-hicle for environmental adoption.
