On 15-th June 2006 from Baikonur cosmodrom the satellite RESURS - DK1 was successfuly launched. The international team of researchers performs the scientific investigations of cosmic rays in a wide energy range with the spectrometer PAMELA on board of this satellite. The neutron detector is a part of the PAMELA spectrometer. It’s task is to separate the cascades of hadron and lepton origin. A brief description of the neutron detector construction and operation mode is presented. The preliminary data on the latitudinal dependence of the neutron fluxes are given and compared with results of previous measurements. The neutron fluxes at the Earth’s day and night sides are compared.
