Ericsson and MediaTek Achieve Decimeter-Level Accuracy on Commercial 5G Network
Ericsson and MediaTek have successfully integrated 3GPP-based GNSS RTK technology into a commercial 5G network. The test achieved stable outdoor accuracy below 30 cm using a handset's built-in antenna.
Ericsson and MediaTek have completed a world-first end-to-end test of high-precision outdoor positioning using 3GPP-based GNSS Real-Time Kinematic (RTK) technology over a commercial 5G network. The test achieved stable sub-30 cm outdoor accuracy, utilizing the handset's built-in antenna.
The solution integrates RTK correction data into the 5G infrastructure through the LTE Positioning Protocol (LPP). Ericsson provided its 5G Core, Network Location, 5G Advanced location services, and Radio Access Network. MediaTek validated the test with its latest 5G modem technology. This system removes the need for proprietary systems or complex external hardware to achieve high-precision positioning.
The technology supports both Unicast and Broadcast GNSS RTK, enabling scalable delivery of high-precision positioning data through mechanisms like SUPL and PosSIBs. Encrypted broadcast is available for authorized users. According to the companies, the technology can support applications such as autonomous vehicles, drones, industrial robots, and in manufacturing and transport, by making precision location services more scalable, interoperable, and accessible.
The test is based on 3GPP Release 16 standards, ensuring global scalability and interoperability between networks and devices. Both Unicast and Broadcast GNSS RTK were tested end-to-end. This allows the solution to switch between unicasting and broadcasting in busy areas, while using unicast in lower-traffic areas or when connected to LTE. The solution also includes security features for encrypted broadcast to authorized subscribers.
The technology supports two types of correction data: Observation State Representation (OSR) and the more advanced State Space Representation (SSR). Ericsson and MediaTek state that this achievement is a milestone, making high-precision positioning more accessible to device makers and enterprises, accelerating use cases in manufacturing, transport, and other sectors.
