Spacecraft Thermal Power Consumption
#robotics, #thermalpower, #intermediate
Each spacecraft can be represented by two major elements: platform and payload. The first includes all the subsystems required to keep the spacecraft healthy, alive and ready to be exploited. The second represents a set of instruments corresponding to experiments / services to be run / provided by the spacecraft.
Spacecraft use electrical power coming from the solar arrays or from the batteries to feed the platform and keep the spacecraft platform within thermal limits during its operational life. The remaining available power can be used by the payloads to do science operations [Science Power = Produced Power - Platform Power - Thermal Power].
The amount of power that will be required by the platform units is known. However, the power that the thermal subsystem will consume is connected to the heaters and their behavior is uncertain. Their behavior depends both on external (e.g. sun distance, solar aspect angle) and internal factors (e.g. units’ status, payloads’ status). As a consequence the current estimation of Power assigned to the Thermal Subsystem has a consistent margin.
The goal of this operational prototype is to better estimate the power that will be consumed by the thermal subsystem in order to determine the power available for doing science. Build an accurate model for thermal power consumption that will increase the spacecraft science return.
A data mining approach will help to solve this problem. However, other approaches are also welcome.
