Zusammenfassung:	One aspect of the disclosed subject matter is seen in a directional drilling instrument that comprises a chassis, a first sensor and a second sensor. The chassis has a longitudinal axis, and the first sensor is coupled to the chassis and oriented at a first angle (w1) relative to the longitudinal axis of the chassis. The second sensor is coupled to the chassis and oriented at a second angle (w2) relative to the longitudinal axis of the chassis. The first and second angles are non-identical and non-orthogonal relative to the longitudinal axis.
