磁罗盘

James Gould and his colleagues have shown that honeybees make use of at least three different sets of back-up cues in addition to their Sun compass; these include the plane of polarization of light, a magnetic compass and a memory for the Sun's position at different times on previous days.

詹姆斯。古尔德及其同仁都证实，除了太阳罗经以个，蜜蜂至少利用了三套不同的后备信号，包括光的偏振平面，磁罗盘及对几天前太阳在不同时间的位置的记忆能力。

The effect of the magnetic interference on the output of magnetic compass was analyzed and a ellipse model for the compass deviation was established. By analysis on the singularity of a coefficient matrix, the error coefficients of the ellipse model were identified by the least square ellipse fitting method.
