The integrated navigation system integrates MEMS inertial navigation and multi-frequency dual-antenna GNSS. With its high accuracy, high reliability and strong adaptability, it has become an ideal choice in complex aviation, land and navigation scenarios.
ER-GNSS/MINS-03 combines intelligent algorithms to provide continuous and stable positioning, attitude and speed information, and can maintain short-term operation in environments with limited satellite signals.
**High-precision navigation**
The navigation information provided has a roll and pitch accuracy of up to 0.02°, and 0.01° after post-processing. The heading can reach 0.05°, 0.01° after post-processing, and the speed accuracy can reach 0.03m/s.
Supporting RTK, the algorithm seamlessly integrates inertial data and satellite signals. When the GNSS is lost for 60 seconds, it can still maintain pitch/roll accuracy of 0.02°, heading of 0.03°, position at 1.5m, and height at 1m, ensuring continuous operation in complex scenarios.
**High-precision core devices**
Built-in high-performance MEMS gyroscope and accelerometer, the gyroscope measurement range is ±400°/s, and the bias instability is <0.3°/h. The measurement range of the accelerometer is ±10g, and the bias instability is <10ug.
**Full-band full-system dual-antenna GNSS**
Built-in full-band full-system dual-antenna positioning and directional GNSS module, supporting GPS/BDS/GLONASS/Galileo/QZSS, dual-antenna design can achieve fast orientation, single antenna high-precision positioning and speed measurement.
**Industrial-grade design and interface**
Precision aluminum alloy shell, weight < 300g, size only 65mm×70mm×45.5mm, taking into account both lightweight and high reliability.
Support RS422, RS232, CAN and TTL interfaces, compatible with a variety of device communication protocols, easy system integration.
