METHOD OF GENERATING AND TRANSMITTING DIFFERENTIAL CORRECTIONS UPON REQUEST FROM SURVEYING SYSTEM TO CONSUMER QUALITY ANALYZING Russian patent published in 2016 - IPC G01C21/20 

FIELD: satellite navigation.

SUBSTANCE: invention relates to navigation and geo location, particularly to satellite navigation methods and GLONASS and GPS space navigation systems navigation fields quality control, generating correcting information and analysis of its quality. Method of generating and transmitting differential corrections upon request from surveying system to consumer quality analyzing includes reception of satellite navigation information, correcting navigation information coming from navigation spacecraft, performed in control-correction station mode, having its own software and mathematical support, navigation and correction information output parameters output by signals of navigation space vehicles to external consumers via self-contained data transfer channel, correction information quality analysis in control-correction station self test mode, performing of differential corrections generated by surveying system for GLONASS and GPS space navigation systems quality analysis and assessment and their transmission by consumer request implies performance of comparison of differential corrections consumer coordinates determining accuracy using satellite navigation equipment in the absence of differential corrections and with them.

EFFECT: method of differential corrections upon request from surveying system to consumer generating and transmitting quality analyzing, providing for surveying system navigation equipment operating mode evaluation and associated GLONASS/GPS users in given area with precision accuracy of positioning, generation of correcting information including differential corrections and generated differential corrections quality monitoring, quality of acquisition and processing of measurement, navigation and other information to perform tasks of assigning quality of automated data transfer via self-contained data transfer channel by surveying system.
