Abstract: Precise positioning using Global Navigation Satellite System (GNSS) requires the GNSS receivers to compensate for the errors caused by distortion in the GNSS signal's path due to atmospheric conditions. The Real Time Kinematics (RTK) technique uses terrestrial reference stations that continuously monitor the quality of GNSS signals and provide information that can be be used by the GNSS receivers in the vicinity of a reference station to compensate for the errors. In this paper, we explore the performance of disseminating the RTK correction information using the Message Queuing Telemetry Transport (MQTT) protocol over 5G. We also compare the indirection costs (latency overheads) of using MQTT over 5G to Ethernet and Wi-Fi, our baselines for high-speed and wireless connectivity respectively, and we highlight the impact of 5G power savings when disseminating GNSS RTK using MQTT.
