© 2019 Published under licence by IOP Publishing Ltd. With the help of the PAMELA magnetic spectrometer continuous measurements of the cosmic-ray fluxes were carried out on board the RESURS-DK1 satellite during 10 years from the end of the 23rd solar activity cycle to the minimum of 24 cycle. The satellite was launched on June 15, 2006 into an elliptical orbit of 350-610 km height. The background channel of the neutron detector which was the part of the spectrometer and served for improving the separation between electrons and protons detected in the calorimeter. Simultaneously it was possible to monitor neutron fluxes in orbit. The technique for processing neutron detector data was developed to reduce the fluctuations of their counting rates associated with instrumental effects. The analysis of the latitudinal dependences of the neutron detector counting rates was donefor various geomagnetic cut-off intervals from 0 to 16 GV during the time from 2006 to 2016. The new technique of data handling was applied for 29 solar proton events. Time dependencies obtained revealed the number of features that require further analysis.
