Introduction
ER-GNSS/MINS-03 is equipped with high-precision and high-reliability MEMS gyroscopes & MEMS accelerometers, 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, Marine and other applications.
Features
High reliability and high precision MEMS gyroscope (zero bias instability
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.
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.
The system can provide accurate integrated navigation information, attitude up to 0.02°, post-processing 0.01°, 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
Application areas
Wide UAV, flight recorder, intelligent unmanned vehicle,
Roadbed positioning and orientation, channel detection,
Unmanned surface vehicle, underwater vehicle.
