Interface Control Document

[mcross8]

Define the interfaces between components and subsystems. Each interface (physical, data, power) should have its own definition. Examples:

The onboard computer will require a set voltage (or voltage range) from the EPS board. Identify the two components (OBC and EPS), the type of interface (power), and the parameters (5V, 200mA max current, connector type).

The onboard computer will also have a data connection to read housekeeping data from the EPS. Identify the two components (OBC and EPS), the type of interface (data), and the parameters (estimated data rate, connector type).

The onboard computer will also have to be mounted to the structure. That's a physical interface. Same story: Identify the two components (OBC and structure), the type of interface (physical), and the parameters (screw, screw type, number of screws, location within the configuration).

This is a large task, but it is needed for CDR and will help give you an appreciation for all of the kinds of components and interfaces that we need to ensure are compatible. We will want to know soon if some components have incompatible interfaces!
