Claim 0:
1. A downhole drilling assembly comprising:
a first proximal end and a second distal end;
a rotatable drill bit positioned at the second distal end of the assembly;
an at bit inclination and azimuth tool positioned immediately proximate and connected to the rotatable drill bit, wherein the at bit inclination and azimuth tool comprises a three axis at bit inclination and azimuth tool inclinometer sensor, and a solenoidal alternating current magnetic coil, wherein the three axis at bit inclination and azimuth tool inclinometer sensor is configured to gather information related to an angular position of the rotatable drill bit;
a bent sub proximally positioned and connected to the at bit inclination and azimuth tool;
a downhole motor proximally positioned and coupled to the bent sub for rotating the drill bit;
a steering tool proximally positioned to the downhole motor and having a three axis steering tool magnetometer sensor and a three axis steering tool inclinometer sensor connected to a communication device; and
a drill string connected to the downhole motor and receiving the steering tool;
wherein the solenoidal alternating current magnetic coil of the at bit inclination and azimuth tool is structured, configured or positioned to communicate the information related to the angular position of the rotatable drill bit gathered by the three axis at bit inclination and azimuth tool inclinometer sensor of the at bit inclination and azimuth tool to a processor of the steering tool, and the communication device is structured, configured or positioned to communicate the information from the processor of the steering tool to a processor positioned at the first proximal end of the assembly.
