METHOD FOR FINDING SATELLITE SIGNALS IN MULTI-CHANNEL RECEIVER FOR SIGNALS OF SATELLITE RADIO-NAVIGATIONAL SYSTEMS Russian patent published in 2008 - IPC G01S5/02 G01S5/14 H04B7/185 

FIELD: radio-navigation, possible use in signal receivers of satellite radio-navigation systems used to determine client location and current time from signals of GLONASS, GPS, and similar radio-navigation systems.

SUBSTANCE: in the method satellite signals included in search list are found, until number of detected signals, which is sufficient for navigation measurements, is produced. In first positions of the search list three satellites are included in arbitrary order which ensure maximal coverage of Earth surface. Further satellites are included into search list in order which is determined by maximal sum of average distances between each one of them and all satellites positioned in the list closer to the beginning. The search for signals of each checked satellite is performed simultaneously using all free channels of receiver with distribution of search range between the channels. Satellite signal search is performed serially based on aforementioned list, starting from first one in the list, until first detection of signal. The search for signals of further satellites remaining in aforementioned list is performed in order determined by maximal difference between the sum of average distances between the satellite selected for check and all earlier checked satellites with undetected signals and the sum of average distances between that satellite and all earlier checked satellites with detected signals.

EFFECT: creation of method for blind finding of signals in multi-channel receiver of satellite radio-navigation signals, ensuring reduction of average search time required to solve navigational problem of the number of satellite radio-navigation system signals.
