  "abstract": "KLYPVE-EUSO (K-EUSO) is a planned orbital detector of ultra-high energy cosmic rays (UHECRs), which is to be deployed on board the International Space Station. K-EUSO is expected to have a uniform exposure over the celestial sphere and register from 120 to 500 UHECRs at energies above 57 EeV in a 2-year mission. We employed the CRPropa 3 package to estimate prospects of testing a minimal model for extragalactic cosmic rays and neutrinos by Kachelriess, Kalashev, Ostapchenko and Semikoz (2017) with K-EUSO in terms of the large-scale anisotropy assuming the Jansson-Farrar (2012) model of the galactic magnetic field. Nearby active galactic nuclei Centaurus A, M82, NGC 253, M87 and Fornax A were considered as possible sources of UHECRs. We demonstrate that an observation of 200 events will allow testing predictions of the model with a high confidence level providing the fraction of from-source events is 12-19%, depending on a particular source, with a smaller contribution for larger samples. Thus the K-EUSO experiment will provide good opportunities for verifying the KKOS model basing on an analysis of the large-scale anisotropy if UHECR flux from any of the sources satisfies the above demands.",
