PROBLEM TO BE SOLVED: To provide a compact automatic collimation surveying airplane allowing normal and reverse observations, a target for the surveying airplane, and an automatic collimation surveying system therefor. SOLUTION: An LED light source 12a havingλ1 of wavelength is provided in a position of a distance L (Fig.4) in an upper side of the center of a reflecting prism P on the vertical center line of the target T, and an LED light source 12b havingλ1 of wavelength is provided in a position of the distance L (Fig.4) in an under side of the center. The LED light sources 12a, 12b are modulation-light-emitted in a frequency f1. An LED light source 12c havingλ2 of wavelength is provided in a position of the distance L (Fig.4) in a left side of the center on a horizontal line passed through the center of the reflecting prism P, and an LED light source 12d havingλ2 of wavelength is provided in a position of the distance L (Fig.4) in a right side of the center. The LED light sources 12c, 12d are modulation-light-emitted in a frequency f2. A two-split photoreception sensor 33A is provided in a telescope part 3 of the survey airplane, modulated lights by the LED light sources 12a, 12b are photoreceived thereby, a two-split photoreception sensor 33B is provided in the telescope part 3 thereof, and modulated lights by the LED light sources 12c, 12d are photoreceived thereby.
