Abstract
The DArk Matter Particle Explorer (DAMPE) can measure $\gamma$-rays in the energy range from a few GeV to about 10 TeV. The direction of each $\gamma$-ray is reconstructed with respect to the reference system of the DAMPE payload. In this proceeding, we adopt a maximum likelihood method and use the $\gamma$-ray data centered around several bright point sources to measure and correct the angular deviation from the real celestial coordinate system, the so called "boresight alignment" of the DAMPE payload. As a check, we also estimate the boresight alignment for some sets of simulation data with artificial orientation and obtain consistent results. The time-dependent boresight alignment analysis does not show evidence for significant variation of the parameters.
