Full-Scenario Coverage: VIPS + RT3000 V4 Enables Seamless Indoor-Outdoor Positioning

As intelligent driving, parking assistance, and vehicle dynamic testing continue to evolve toward increasing complexity, the continuity of positioning has become a key factor affecting test validity.
When a vehicle transitions from outdoor to indoor environments, or from GNSS-covered areas into GNSS-denied zones, traditional high-precision positioning systems often face challenges such as loss of positioning signals, trajectory jumps, and discontinuous attitude data. These issues pose higher requirements for AVP, automated parking, and high-precision performance verification.

Recently, Zeer Testing completed an in-depth integration test of the Racelogic VIPS indoor positioning system with the OxTS RT3000 V4 inertial navigation system, successfully achieving automatic and smooth switching between indoor and outdoor positioning sources. This has established a truly full-scenario high-precision positioning solution.

In this test, Zeer used the RT3000 V4 as the core inertial navigation platform and integrated VIPS as the high-precision indoor positioning source, allowing GNSS and UWB data to be seamlessly fused and automatically switched within the RT system. Unlike traditional methods that rely on post-processed trajectory stitching, this solution enables cooperative operation of positioning sources at the navigation computation level, ensuring continuity and consistency of both positioning and attitude data at the system level.

Test results show that in pure indoor environments, the system achieves stable centimeter-level positioning accuracy using VIPS, while maintaining the same level of precision outdoors with RTK-GNSS. In indoor-outdoor transition areas, the positioning sources switch automatically, producing continuous trajectories without noticeable delay or jumps, meeting the practical requirements for high-dynamic vehicle testing and functional validation.

Through this test, Zeer has completed system-level integration verification of VIPS and RT3000 V4, successfully enabling continuous high-precision positioning for vehicles in indoor, outdoor, and transition areas. This positioning capability now reliably supports ABD drive tablets in both indoor and outdoor scenarios, providing a unified and dependable positioning reference for function triggers, path execution, and data recording. The solution can be widely applied to automated parking, AVP, and mixed indoor-outdoor path testing, offering a comprehensive and implementable technical foundation for full-vehicle functional validation in complex scenarios.
