Introduction
ER-GNSS/MINS-05 is a Cost-efficient GNSS aided MEMS INS with a highly reliable MEMS inertial measurement unit and a dual-antenna full-system full-band positioning and directional satellite module. The integrated navigation fusion algorithm can provide continuous, accurate and reliable positioning, attitude and speed information. It has a variety of communication interfaces and provides standardized user communication protocols, which can meet the aviation, land, marine and other applications.
Features
1.High reliability and low cost MEMS gyroscope (bias instability <2°/h) and MEMS accelerometer (bias instability <25ug). 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 zero bias performance.
2.Built-in full-band full-system dual-antenna positioning and orientation GNSS module, supporting single-antenna high-precision positioning and velocity measurement, supporting dual-antenna fast orientation function.
3.The system can provide accurate integrated navigation information, attitude up to 0.1°, post-processing 0.03°, heading 0.1°, post-processing 0.05°
4.Variety of data interface, more easy to install and use, support RS422/RS232 and CAN.
5.Precision aluminum alloy shell, high reliability, can be widely used in land, aviation, navigation
