VINS-D15 Visual-Inertial Fusion Navigation System, MEMS visual inertial fusion unit for UAV GNSS denied navigation

VINS-D15
Visual-Inertial Fusion Navigation System

Product Overview: Visual-Inertial Fusion Navigation

The VINS-D15 visual-inertial fusion navigation system adopts high-precision MEMS inertial sensors fused with visual navigation algorithm, built exclusively for UAV platforms. This MEMS inertial navigation drone module integrates high-performance MEMS gyroscopes, MEMS accelerometers and GNSS receiver chips. It measures angular rate and acceleration of the UAV, accepts real-time GNSS dual-antenna and heading inputs, and runs navigation computation to output real-time heading, 3D velocity, position and attitude data for drones. It maintains the published navigation accuracy under GNSS-denied conditions across desert, forest and lake environments. As a reliable solution for GNSS-denied navigation for UAV, it solves positioning drift and failure when satellite signals are blocked or intentionally jammed, ideal for applications requiring GPS denied navigation for drone in complex terrain.

Core Advantages

The VINS-D15 supports full-band GNSS reception with ultra-low 3W steady-state power consumption and a built-in adaptive attitude algorithm. When GNSS satellite signals drop out, the internal self-correction logic holds stable horizontal attitude accuracy during UAV flight. It supports RTK differential input, zero velocity update and flight constraint algorithms to deliver reliable dead reckoning. Unlike basic inertial modules that accumulate large drift quickly without GNSS, this visual-inertial fusion design leverages visual feature matching to constrain navigation error continuously for longer-duration flights.

Integration Notes

The VINS-D15 is purpose-built for UAV integrators working in challenging outdoor terrain. It holds specified positioning accuracy in GNSS-denied scenarios such as deserts, forests and lakes, delivering continuous positioning when GNSS is jammed or unavailable. The fusion algorithm tightly couples visual observations and inertial measurements to suppress long-term drift. It supports standard serial and CAN bus protocols for straightforward integration with flight controllers, autopilots and onboard computers. NovaSys provides formal datasheets, wiring guides and technical support for bulk orders. It is widely selected by aerial survey teams and drone developers who require reliable positioning without stable satellite coverage.
