Abstract
A system for making bottom hole assembly (BHA) measurements in the bottom hole assembly (BHA) includes a vibration mechanism configured to use mechanical energy provided by a mechanical energy source to produce a plurality of vibration beats at the BHA. At least one vibration sensor detects the plurality of vibration beats generated by the vibration mechanism. A controller generates a waveform responsive to the detected plurality of vibration beats. The waveform is generated in a first configuration when the BHA has a first weight on bit (WOB) or revolutions per minute (RPM) measurement based on the detected plurality of vibration beats and the waveform is generated in a second configuration when the BHA has a second WOB or RPM measurement based on the detected plurality of vibration beats.
