Long-Range Real-Time Precise Navigation with Three Frequency GNSS

    Graphical Abstract
    • Abstract
  • The most valuable benefits from three frequency GNSS are that several extra-widelane(EWL) combinations can be constructed.A new method for long-range real-time precise navigation is proposed according to this.The position experiment with employment of about 90 km baseline demonstrates that 1.5 cm RMS accuracy can be achieved for ionosphere delays after 2 min smoothing and 3 cm for horizontal coordinates is achieved after 1 min smoothing,which means that the precise navigation can be set up with only one reference station by using three frequency GNSS in the medium scale cities in China.
