In industrial drone operations, weak or obstructed GNSS signals are common, and navigation drift is a major obstacle to precise operations, easily leading to data deviations and flight hazards. High-precision MEMS integrated navigation systems, powered by both GNSS and inertial measurement, completely solve this problem.
Key Question: Will navigation really not drift when GNSS signals are weak?
The answer is clear: There will be no significant drift. Even with weak or briefly lost GNSS signals, high-precision navigation output can still be maintained. Unlike traditional single-signal GNSS navigation, this system integrates satellite positioning and inertial measurement technologies, not relying on a single signal, providing dual protection to ensure online accuracy.
Dual Protection: Eliminating Drift and Ensuring Stable Accuracy
Protection 1: High-Precision Inertial Module, Stable Even in Lockdown
Built-in high-reliability MEMS gyroscope and accelerometer accurately capture UAV motion information, providing stable data even without GNSS signals, preventing drift at its source. Even with complete signal loss, it can still output high-precision data for 60 seconds, with attitude and heading accuracy stable at 0.01°, ensuring uninterrupted operation.
Protection 2: Dual-Antenna Multi-Constellation, Enhanced Weak Signal Positioning
Integrated dual-antenna full-frequency satellite module, supporting multi-constellation compatibility, maximizes the capture of weak GNSS signals. Combined with RTK technology, it achieves centimeter-level positioning, complementing the inertial module, providing dual protection to eliminate drift.
Suitable for Industrial Scenarios, Convenient and Durable
The system is compact and lightweight, with a precision aluminum alloy shell suitable for extreme environments from -40℃ to +80℃. Multiple interfaces are compatible with various UAVs, easily landing for surveying, inspection, and other industrial operations, making drift-free navigation a standard feature of industrial UAVs.
Drift-free navigation ensures efficient operation. This integrated navigation system uses dual technologies to overcome the challenge of weak GNSS signals, ensuring the precise flight of industrial drones.
