Introduction
The ER-GNSS/MINS-01 features high-precision and reliable MEMS gyroscopes and accelerometers. It integrates a dual-antenna, full-system, full-band positioning and orientation satellite module. With its integrated navigation fusion algorithm, it delivers continuous, accurate, and reliable positioning, attitude, and speed information, even under complex GNSS conditions. It offers a variety of communication interfaces and standardized user communication protocols, making it suitable for applications in aviation, land, marine, and more.
Features
- High reliability and high precision MEMS gyroscope (bias instability <0.02°/h) and large range high precision MEMS accelerometer (±60g, bias instability <2μg).
- The working temperature is -40℃~+80℃, and the temperature compensation of the gyroscope and accelerometer is carried out in the working temperature range, which has better bias performance.
- Built-in full-band full-system dual-antenna positioning and orientation GNSS module, which supports single-antenna high-precision positioning and velocity measurement, and supports dual-antenna fast orientation function.
- The system can provide extremely accurate integrated navigation information, attitude up to 0.01°, post-processing 0.004°, heading 0.05°, post-processing 0.01°
- Variety of data interface, more easy to install and use, support RS422/RS232 and CAN
- Precision aluminum alloy shell, high reliability, can be widely used in land, aviation, navigation.
