1. A method comprising:
- receiving, at a controller, data representative of a first detected rotational characteristic of a drill string sensed at a first downhole location on the drill string;
calculating, at the controller, a second rotational characteristic corresponding to a second downhole location on the drill string based, at least in part, on the received data;
transmitting data representative of the calculated second rotational characteristic to a tool at the second downhole location,receiving, by the tool, the data representative of the calculated second rotational characteristic, andoperating the tool at the second downhole location utilizing the received calculated second rotational characteristic corresponding to the second downhole location.

Abstract
A method for sharing information between components of a subterranean drill string. The method can include receiving, at a controller, data representative of a detected rotational characteristic of a drill string sensed at a first location on the drill string. Further, the method includes calculating, at the controller, a rotational characteristic corresponding to a second location on the drill string based, at least in part, on the detected data, and transmitting data representative of the calculated rotational characteristic to the second location.

22. A drilling system comprising:
-
a subterranean drill string; a plurality of rotational characteristic sensors arranged on the drill string; a drill string communication system; and a controller, located at a first downhole location; wherein the controller receives data representative of a detected first rotational characteristic of the drill string sensed by one of the plurality of rotational characteristic sensors at the first downhole location on the drill string, the controller calculates a second rotational characteristic corresponding to a second downhole location on the drill string, based, at least in part, on the detected data; and data representative of the calculated second rotational characteristic is received by a tool at the second downhole location, the received calculated second rotational characteristic used to operate the tool at the second downhole location. - View Dependent Claims (23, 24, 25, 26, 27)

28. A method for sharing information between components of a subterranean drill string, the method comprising:
-
receiving, at a downhole controller, data representative of a detected first characteristic of a drill string;
sensed at a first downhole location on the drill string; andcalculating, at the controller, a corresponding second characteristic in dependence upon the received data representative of the detected first characteristic of the drill string sensed at the first downhole location on the drill string for utilization at a tool located at another downhole location than the first location on the drill string; and
operating the tool using the second characteristic. - View Dependent Claims (29)
