The integrated navigation system of GNSS combined with INS can make up for the shortcomings of GNSS when signals are blocked or interrupted and the problem of low satellite refresh rate, achieving better navigation performance.
Our integrated navigation ER-GNSS/MINS-01 has ultra-high precision at the surveying and mapping level. It can provide continuous and high-precision position, speed and attitude information.
**Surveying and mapping-level high-precision navigation**
The combined navigation information provided has a roll and pitch accuracy of up to 0.01°, and 0.004° after post-processing. The heading can reach 0.05°, 0.01° after post-processing, and the speed accuracy can reach 0.03m/s.
Supports RTK positioning, automatically identifies RTCM, and enters RTK state. In the event of satellite lock loss, the working state can also be maintained for a short time.
In the case of RTK interruption for 60 seconds, the roll and pitch accuracy can be maintained at 0.01°, and the heading accuracy can be maintained at 0.01°. The position is maintained at 0.5m and the height is maintained at 0.1m.
**High-precision core components**
Built-in high-performance navigation-grade MEMS gyroscopes and accelerometers, the gyroscope measurement range is ±200°/s, and the bias instability is <0.02°/h. The accelerometer measurement range is ±60g, and the bias instability (Allen curve) is <2ug.
**Full-band full-system**
Built-in dual-antenna positioning and orientation GNSS module, supports all major satellite navigation systems in the world, and can perform high-precision and fast positioning and orientation. It is also compatible with all frequency points to ensure the best positioning effect at any location in the world.
The built-in satellite receiver has strong anti-interference ability, can still provide accurate positioning in complex electromagnetic environments, and also supports multiple communication interfaces.
**Small size and light weight**
The size is only 65×70×45.5mm, the weight is less than 300g, and the aluminum alloy shell is used to ensure the reliability of the product. And the operating temperature range can reach -40°C to 80°C, which is suitable for most working environments.
**Multi-field application**
Applicable to large unmanned aerial vehicles, flight recorders, intelligent unmanned vehicles, mobile surveying and mapping, roadbed positioning and orientation, etc.
