UrduA cutting-edge study shows that integrating 5G technology with the BeiDou Navigation Satellite System (BDS) can significantly boost Real-Time Kinematic (RTK) positioning accuracy in urban environments. By combining 5G measurements with BDS, this approach addresses common challenges like signal blockages and visibility issues in cities. The integration reduces positioning errors and enhances the success rate of ambiguity resolution, crucial for applications in autonomous systems and the Internet of Things (IoT).
