Аннотация: The wide-angle Air-Cerenkov array HiSCORE is a major component of the TAIGA facility in theTunka valley, built for Gamma Astronomy and Cosmic Ray research. HiSCORE will contain 120stations distributed over a 1 km2area.Here, we report a multi-year detection of light flashes in HiSCORE from the LIDAR on-boardthe Sun-synchronous CALIPSO satellite, obtained in 2015-2021. The 100 mJ laser (532 nm) isobserved up to distances beyond 10 km away from the ground light spot. This study complementsfirst observations of a space-based LIDAR, performed in 2015-2017 with the 28 station HiSCOREprototype and the CATS-LIDAR on-board the International Space Station. We present HiSCOREcalibration methods developed for the LIDAR events to optimize the pointing resolution of the array;and additionally perform a detailed array performance analysis over 6 years.The angular resolution for this special class of HiSCORE events - bright flashes, with a plane wavelight front - is found to be ∼0.05◦, which is below the high-energy limit of ∼0.1◦for air-showers.The satellite event sample allows to optimize rare event search strategies, like for optical flashesof astrophysical origin. We will also report on scheduled joint LIDAR observation by HiSCOREand TAIGA-IACTs, as well as optical ground instruments - to independently calibrate the absolutearray-pointing precision.
