Abstract
A transmitter is carried proximate to an inground tool for sensing a plurality of operational parameters relating to the inground tool. The transmitter customizes a data signal to characterize one or more of the operational parameters for transmission from the inground tool based on the operational status of the inground tool. A receiver receives the data signal and recovers the operational parameters. Advanced data protocols are described. Pitch averaging and enhancement of dynamic pitch range for accelerometer readings are described based on monitoring mechanical shock and vibration of the inground tool.
