* @details
* Each parameter has a unique parameter ID. The first byte of the parameter
* ID is the domain ID which can be used to identify unqiue spacecraft domains
* (e.g. control and sensor domain in the AOCS controller).
*
* The second and third byte represent the matrix ID, which can represent
* a 8-bit row and column number and the last byte...
*
* Yeah, it it matrix ID oder parameter ID now and is index a 16 bit number
* of a 8 bit number now?
