Abstract: A downhole communication system includes a mud pulse generator that generates a set of pressure pulses in a pattern, the pattern including encoded data. A roll stabilized platform includes a turbine that is rotatable in response to the pressure pulses. The rotational rate of the turbine is correlated with a pressure value. A processor on the roll stabilized platform demodulates the pressure pulse pattern, and then decodes the encoded data.
