Abstract
A data sonde for use in horizontal drilling is provided, the data sonde comprising an antenna for emitting a first modulated signal from the data sonde, the first signal comprising zero and non-zero emission components in different periods, and a receiver for receiving an intermittent second data signal during first signal zero emission periods. A method of operation of the same is also provided.

A data sonde for use in horizontal drilling, the data sonde comprising:
- emitting means for emitting a first modulated signal from the data sonde, the first signal comprising zero and non-zero emission components in different periods;
- and
- receiving means for receiving an intermittent second data signal during first signal zero emission periods.
A method of bi-directional communication between a data sonde for use in horizontal drilling, and a device external to the sonde, the method comprising:
- emitting a first modulated signal from the data sonde, the first signal comprising zero and non-zero emission components in different periods;
- and
- receiving an intermittent second data signal during first signal zero emission periods.
A data sonde for use in horizontal drilling, the data sonde comprising:
- an antenna;
- a receiver;
- and
- circuitry configured to control the antenna to emit a first modulated signal from the data sonde, the first signal comprising zero and non-zero emission components in different periods, and to control the receiver to receive an intermittent second data signal during first signal zero emission periods.
A system for communicating between a data sonde and a remote apparatus, the system comprising:
- an antenna;
- a receiver;
- circuitry configured to control the antenna to emit a first modulated signal from the data sonde, the first signal comprising zero and non-zero emission components in different periods, and to control the receiver to receive an intermittent second data signal during first signal zero emission periods,
- a data sonde, and
- a surface control unit physically coupled to the data sonde, the physical coupling providing a bi-directional communication channel between data sonde and surface control unit.
