Assisting navigation localization method and system
2017
The invention discloses a kind of assisting navigation localization method and systems.The described method includes: receiver receives current GNSS signal, it is less than predetermined power in the power of the current GNSS signal, and when the carrier-to-noise ratio of the current GNSS signal is less than default carrier-to-noise ratio, obtain the GNSS auxiliary information sent by GNSS auxiliary reference station by CDRadio channel, it is completed according to the GNSS auxiliary information the capture of current GNSS signal, tracking and calculates pseudorange difference with the position vector of the determination receiver, and the location information of the receiver is determined according to the position vector, to realize that assisting navigation positions.The GNSS signal auxiliary information that the present invention is sent by CDRadio channel come realize assisting navigation position, mobile Internet is solved to transmit the instability problem of GNSS signal auxiliary information, has been obviously improved the practical ranges and user experience of highly sensitive GNSS receiver.
