Technical Description We proposed a positioning integrated gyroscope (PIG) with a unit price of less than US$3,000. A pilot test was conducted in the tunnel section. The positioning error of the MEMS gyroscope was 4,300 meters at a moving distance of 7.8 kilometers,because there was no GNSS signal in the tunnel. The signal of GNSS module only uses the built-in IMU for positioning, the maximum error is also 348 meters. We move 7.8 kilometers, the error is 89 meters73 meters, the overall error are MEMS (55), GNSS (4.5),the team's module (1.1), the internationally marketed inertial FOG (0.9).
Scientific Breakthrough A pilot test was conducted in the tunnel section. The positioning error of the MEMS gyroscope was 4,300 meters at a moving distance of 7.8 kilometers,because there was no GNSS signal in the tunnel. The signal of VBOX-GNSS/IMU module only uses the built-in IMU for positioning, the maximum error is also 348 meters. Our team’s modulethe internationally marketed FOG achieve similar accuracy errors. We move 7.8 kilometers, the error is 89 meters73 meters, the overall error are MEMS (55), GNSS (4.5),the team's module (1.1), the internationally marketed inertial FOG (0.9).
Industrial Applicability The global fiber optic gyroscope market will reach an economic scale of USD 10.37 million in 2022. Low-medium-precision fiber optic gyroscopes account for about 45 of the overall market. The range meets the specifications for self-driving cars. The bias drift accuracy of our team's integrated optical gyroscopes is 0.1 to 1deg/hr, the application is locked in the blank space between MEMStraditional FOG,unmanned vehicle systems such as LV3-LV5 self-driving vehicles, underwater unmanned vehicles, UAVs, etc. are locked.
