FindAUTO High-Precision Positioning

FindAUTO is Qianxun Spatial Intelligence's mass-production high-precision positioning solution for intelligent and autonomous vehicles, sold internationally under the SpatiX brand. Higher levels of driving automation need a lane-level absolute position that stays available through bridges, tunnels and bad weather, when cameras and radar are degraded.

The solution has three parts. FindAUTO Service is a cloud correction service that broadcasts satellite-ground integrated SSR corrections, ground-based OSR (RTK) corrections and assisted-GNSS data from Qianxun's GNSS augmentation station network, and can be privately deployed. FindAUTO Client is a positioning engine running PPP-RTK with tightly coupled GNSS+INS and terminal integrity monitoring. FindAUTO chip modules (MC282 dual-frequency, MC382 all-system full-frequency) package the algorithms on automotive-grade hardware with BeiDou-3 signal support. Together they output real-time position, velocity, time and attitude.

For its autonomous-driving service Qianxun quotes PPP-RTK accuracy of CEP95 < 30 cm in open sky, positioning integrity of 10^-7/h, ISO 26262 ASIL-B for the terminal and IEC 61508 SIL-2 for the service; coverage is mainland China. Qianxun also supports hardware selection, system integration and acceptance testing, and after start of production offers multi-antenna/GNSS/IMU tuning, vehicle IMU calibration and a quality-monitoring platform.

Published deployments include XPeng P7 (XPILOT 3.0), GAC Aion V and Aion LX, FAW Hongqi E-HS9 and SAIC's first L4 heavy trucks at Yangshan Port. Qianxun reports more than 100 vehicle models awarded SOP designations.
