The invention discloses a two dimensional space track tester based on a double-axis optical fiber gyro, and belongs to the field of moving track engineering test. The tester comprises a host computer, an interface system connected with the host computer, a trochometer, an upper computer and an optical fiber gyro connected with the interface system, wherein the optical fiber gyro is a double-axis optical fiber gyro formed by integrating two single-axis optical fiber gyros into a gyro body; and sensitive axes of the double-axis optical fiber gyro are mutually perpendicular and can simultaneously measure running tracks in two directions on the same plane. The tester integrates the two single-axis optical fiber gyros into one gyro body, and sensor information is provided for the space runningtrack tester through the one double-axis optical fiber gyro. At the same time, only one set of interface equipment needs to be matched so as to solve the problems of large volume and lower integration of the prior track tester, and simplify the electric design simultaneously.
