Mapping-level & Ultra-precision GNSS/MEMS INS
Introduction
ER-GNSS/MINS-01 is equipped with MEMS gyroscope and MEMS accelerometer with extremely high precision and reliability, and integrates a dual-antenna full-system full-band positioning and orientation satellite module. It is equipped with an integrated navigation fusion algorithm, which can provide continuous, accurate and reliable positioning, attitude and speed information under complex GNSS conditions. It has a variety of communication interfaces and provides standardized user communication protocols, which can meet the aviation, land and other applications.
Features
1.High reliability and high precision MEMS gyroscope (bias instability <0.02°/h) and large range high precision MEMS accelerometer (±60g, bias instability <2ug).
2.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.
3.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.
4.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°
5.Variety of data interface, more easy to install and use, support RS422/RS232 and CAN
6.Precision aluminum alloy shell, high reliability, can be widely used in land, aviation, navigation.
