A 5G/GNSS integrated positioning method
The emergence of the fifth generation (5G) positioning provides a promising opportunity to augment global navigation satellite system (GNSS) in some GNSS-challenged environments. This paper presents a 5G code and carrier phase receiver, which produces code and carrier phase measurements from trackin...

The emergence of the fifth generation (5G) positioning provides a promising opportunity to augment global navigation satellite system (GNSS) in some GNSS-challenged environments. This paper presents a 5G code and carrier phase receiver, which produces code and carrier phase measurements from tracking 5G New Radio Positioning Reference Signal (PRS). Meanwhile, to handle the clock error between 5G receiver and transmitter, a round-trip time (RTT) ranging method is proposed to provide accurate 5G code-phase based range estimate using 5G PRS, and RTT method avoids clock error estimation or compensation. Then, a 5G/GNSS integrated positioning framework is proposed to combine GNSS pseudo-range measurements with 5G code-phase based range estimates. Experiments are presented of a ground platform positioning with the 5G/GNSS software defined radio transceivers, and the experimental results show that 5G/GNSS integrated positioning improves the standalone GNSS solution in terms of accuracy and availability. Meanwhile, the proposed 5G RTT ranging method shows maximum range root mean square error (RMSE) of 1.109 m. |
