The Jiangmen Undergrond Neutrino Observatory (JUNO) is an upcomming multipurpose experiment focused on resolving the neu- trino mass ordering, an open question of modern neutrino physics. With its 20-kton liquid scintillator target instrumented with 18000 20” PMTs and 25600 3” PMTs the JUNO detector will measure neu- trino spectrum from nuclear reactors at about 53 km distance with 3% energy resolution at 1 MeV. It will allow to resolve the oscillation pattern driven by both the larger mass splittings (∆m231 and ∆m232) and the smaller one (∆m21). This will allow JUNO alone to determine the correct mass ordering at a 3-sigma confidence level within 6 years and provide valuable input for joint analyses with other experiments. Besides that JUNO will measure three oscillation parameters: θ12, ∆m21 and ∆m231 with better than 0.6% accuracy, largerly improving the current precision.
