Abstract
We are developing a fluorescence detector (FD) calibration device called as Opt-copter which consists of an UV LED, a high accuracy GPS and an unmanned aerial vehicle (UAV). Opt-copter is a standard light source to be used to calibrate the Telescope Array (TA) FDs. The primary characteristic of Opt-copter is its high portability which enables us to put the light source on any position we want in the F.O.V. of FDs. Our upgraded UAV, has improved flight reliability and payload capacity. The calibration procedure is established by a test observation at the TA FD site. We evaluated the flight accuracy and developed a method to measure the FD geometry. We will report the current status of Opt-copter.
