The mission profile, or life profile, is an important step to consider when using the reliability.space method.

For space applications, mission profiles are based on the same main phases. Furthermore, the stress applied on electronic equipment of satellites is mainly linked to the temperature, in addition to the electrical stresses dealt with directly at part level. From the regular mission profile definitions from FIDES, the other stresses such as vibrations, humidity and chemical pollution are considered, but they are mainly present only during the launch phase.

So, to define accurately the mission profile, it is necessary to know:

• the type of mission of the satellite such as geostationary, Low Earth orbit, middle orbit, science satellite or other mission;
• the different phases of use (on) and no use (off) of the equipment;
• the location of the equipment on the platform or on the payload in order to estimate all the relevant stresses.

You can navigate through categories by clicking them on the left. Make sure to validate you entries at the end of each category (Validate parameters) otherwise they will be deleted.
Once all categories are filled, you can validate the phase click the Validate phase button. You can edit a phase by double-clicking it from the sum-up table below.
