Huawei’s Xingji (星迹, or “star trail”) is a positioning system designed for places where ordinary satellite navigation can lose accuracy: tunnels, elevated roads, sports tracks and indoor spaces. Instead of relying on GNSS—global navigation satellite systems—alone, it combines satellite measurements with specialised chips, motion-estimation algorithms and environmental or map data. 6

Huawei executive Li Xiaolong introduced the technology at a device innovation briefing on October 12, 2026. Its first listed devices are the Mate 90 series and WATCH GT Runner 2. The company’s pitch is not one positioning method for every situation, but a set of techniques tailored to different environments. 6
8
Elevated roads: identifying the right lane
On elevated roads, Huawei combines HiSilicon short-range chips with GNSS carrier-phase measurements. The company says this improves ranging accuracy by more than tenfold and enables sub-metre positioning for lane-level navigation. The practical aim is to help navigation distinguish lanes on complex roads—for example, when a driver needs to choose the correct lane before an exit. 5
7
That tenfold figure refers to ranging accuracy. It should not be read as a tenfold improvement in every aspect of navigation or in every driving condition. 7
Tunnels: keeping a location estimate without satellite signals
Satellite signals are obstructed in tunnels, so Xingji uses AI-based speed estimation and geomagnetic matching to estimate a vehicle’s position. Huawei says this can provide lane-level positioning regardless of tunnel length or driving time, and describes the capability as the industry’s only tunnel lane-level positioning solution. Those are company claims; the available reports do not independently establish them as guarantees. 5
7
Running: different tools for phones and watches
For track navigation, the Mate 90 series combines RTK (real-time kinematic positioning) with AI-PDR, an AI-assisted form of pedestrian dead reckoning. Huawei says this supports lane-level guidance on running tracks. 6
9
The WATCH GT Runner 2 takes a hardware approach: its 3D floating antenna is designed to improve satellite reception. Huawei reports that GNSS signal strength is 5.4 dB higher than on the first-generation running watch, with the aim of improving tracking in more challenging outdoor environments. 6
9
Skiing: reconstructing fast-moving routes
For skiing, Xingji fuses GNSS data with SkiDR, a dead-reckoning approach tailored to skiing. Huawei reports five times finer route detail, twice the dynamic responsiveness and 98% accuracy for ski distance. These figures are specific to the skiing claims and are not a general measure of positioning accuracy across other activities. 9
Huawei also says its on-watch ski maps cover more than 3,000 resorts, with ski-run matching accuracy above 97%. 9
Underground car parks: remembering the floor and parking spot
Xingji uses 3D road-network matching to record where a car is parked in an underground garage. Huawei-reported figures put floor-identification accuracy above 95%, with position error under 10 metres. Precise Car Finder 2.0 on the Mate 90 series is reported to improve parking-location accuracy by 50% compared with the Mate 80 and to support more than 30,000 underground garages. 5
7
Shopping malls: extending location services indoors
Huawei and its partners are also extending location-based services into commercial buildings. Reports say the system supports 500,000 commercial-district geofences and 17,000 buildings with indoor positioning. Petal Maps offers store-level navigation in more than 260 malls, with Huawei expecting to add over 200 malls per month. That monthly figure is a forecast, not a count of malls already covered. 5
9
The main takeaway is that Xingji is a collection of scenario-specific positioning techniques, not a blanket promise of sub-metre accuracy everywhere. The figures above are reported by Huawei or in coverage of its briefing; the available sources do not provide enough detail to independently assess all the testing conditions or comparisons.
