To fully verify the performance of the I3700 integrated navigation system in real-world application scenarios, Micro-Magic Inc conducted a comprehensive and rigorous product performance test in response to customer requirements. The testing covers six typical scenarios including open roads, urban canyons, tree-lined roads, underground garages, long tunnels, and elevated auxiliary roads, comprehensively evaluating the positioning accuracy and stability of the system in various complex environments.
This test uses the NovAte PwrPak7D-E1 high-precision integrated navigation system as the true value reference, and uses Waypoint Inertial Explorer professional software for post-processing and smoothing calculations to ensure the high reliability and centimeter level accuracy of the test data.
The test results show that in an open environment with good satellite signals, the I3700 has a CEP95 (95% positioning error) of only 4.64 centimeters and a horizontal RMS error of 2.62 centimeters. The system availability is as high as 100%, achieving true centimeter level positioning. In environments with severe signal obstruction such as urban canyons and tree-lined roads, I3700 still performs robustly, with CEP95 reaching 3.47 cm and 6.99 cm respectively, and horizontal RMS error controlled at 1.79 cm and 4.77 cm, fully demonstrating its strong multipath suppression and signal recovery capabilities.
In the more challenging scenario of complete loss of GNSS signal lock, the pure inertial navigation performance of I3700 becomes the biggest highlight. In the high-speed tunnel crossing test that lasted for about 3 minutes and was 3003 meters long, the system's horizontal positioning RMS was 4.28 meters, speed RMS was 6.57 centimeters per second, and heading angle RMS remained stable at 0.237 °, fully demonstrating its excellent drift control capability in long-term, high dynamic GNSS denial environments.
The I3700 integrated navigation system integrates high-performance MEMS-IMU and full constellation, full frequency dual antenna RTK GNSS receiver. The gyroscope has a zero bias instability of 1.6°/h and the accelerometer has a zero bias instability of 18 μ g; RTK positioning accuracy can reach 1 centimeter, and dual antenna direction finding accuracy is 0.2° (1-meter baseline); Achieving 100% availability in open environments, maintaining high-precision output even in signal occlusion and loss of lock scenarios, suitable for various high-end application scenarios such as drones, unmanned ships, autonomous driving, agricultural machinery, and satellite communication antenna stabilization platforms.
Micro-Magic Inc stated that the I3700 integrated navigation system demonstrated excellent comprehensive performance in this rigorous test, not only achieving centimeter level positioning in open environments, but also maintaining stable and reliable pose output under extreme conditions of GNSS signal loss with powerful inertial navigation algorithms. Its excellent environmental adaptability and positioning accuracy fully meet the urgent demand of current intelligent equipment for high-precision and high reliability navigation systems.
