摘要

In this research, ultra-wideband radios (UWBs) are integrated into the real-time kinematic (RTK) algorithm using differential GPS techniques to achieve a highly precise relative positioning vector between GPS antennas. This has potential applications including an autonomous leader-follower scenario or an unmanned aerial refueling scenario. The UWBs give a range measurement between antennas, while the RTK solution gives a three dimensional relative positioning vector. This UWB range measurement can be integrated into the RTK algorithm to add robustness and increase accuracy. When two GPS receivers are within a close proximity, most of the errors that degrade the GPS signal are correlated between the two receivers and can be mitigated by using differential techniques. This can be done using either a static base station, as is the case for RTK, or using a dynamic base, as is the case for DRTK. These algorithms are explained and results are shown in this paper.
