Abstract
The present invention relates to a program controlled apparatus for providing rapid calibration and update of sensor parameters in a push drill guidance apparatus which is remotely controllable from microprocessor circuitry. A special calibration program is set into non-volatile memory for coaction with the control processor to compute sensor parameters for storage and recall during normal programmed guidance operation.
