A valve control unit includes a data reading / selecting unit, which reads each of signals transmitted onto a serial bus, and selects a flow rate data signal from among the read signals. Therefore, the valve control unit can acquire the flow rate data signal from the serial bus without allowing the flow rate data signal to pass via the master IC.

Moreover, it is not necessary to provide an additional instrument for transferring analog signals between slave devices, and accordingly, a size increase and cost increase of an apparatus can be suppressed.

A ballistic descent vehicle comprises an airframe, one or more control surfaces for controlling a descent of the vehicle, a controller, and a sensor suite to estimate both relative position, velocity, and flight path angle. Such a controller guides the vehicle, via the control surfaces, based on the estimated vehicle states, and a preprogrammed equivalent airspeed versus flight path angle two dimensional surface.
