### DESCRIPTION ( Introduce yourserlf and your project)

The purpose of the housekeeping is to monitor and relay control commands to the several subsystems that constitute a satellite All the control commands are provided by the CPU.

The principal task that perform the HK are listed below:

1. - Sensor monitoring of different subsystems in order to detect faults.

2. - Generation of alarms for the CPU.

 3. – Distribution of telecommands to several subsystems.

4. – Telemetry acquisition from all subsystems.

5. – Monitoring of the status of the various electronic system of the focal surface.

6. – Switching between main and spares boards when appropriate.

7. – Interaction with the power distribution system of the telescope in order to turn on/off the secondary power supplies.

Our principal goal, for this stage of development, is to validate the electronic that is going to control the Housekeeping. The validation is going to made through a stratospheric flight.

### TECHNICAL DETAILS (With project photos)

Our project consists of a Microcontroller that act as a Housekeeping, this microcontroller monitors voltage, current and temperature of three test benches. We monitor the behaviour of the microcontroller in extreme environments such as the stratosphere.

### Words to PCBWay

We really appreciate all the support that PCBway give us
