Pulsating Aurora Imaging Photometers Stereoscopic System (PAIPS) is being developed in Skobeltsyn Institute of Nuclear Physics of Moscow State University (SINP MSU) and Polar Geophysical Institute (PGI) to be installed in Kola peninsula. The system is based on two lens telescopes with matrix of multi-anode photomultiplier tubes as photodetectors placed in two high latitude observatories of Polar Geophysical Institute. Telescopes provide simultaneous observations of a large volume of atmosphere at altitudes range 50-100~km with high temporal resolution (up to 2.5 µs) and spatial resolution of about 2 km. This is a novel system for pulsating aurora study aimed to measure fine temporal structure and altitudinal distribution of pulsating aurora emission. This allows us to estimate maximum energies of precipitating electrons responsible for the pulsating aurora occurrence. The system can be used for other atmospheric phenomena studies: meteors, transient luminous events etc. with a high temporal resolution and high sensitivity in continuous monitoring mode. The design of the system, its performance and first examples of measurements made by the first telescope installed in Verkhnetulomsky observatory on September 2021 are presented. The research is supported by a grant from the Russian Science Foundation (project No.22-62-00010).
