Introduction

ER-MINS-5680 MEMS Integrated INS

Introduction

This MEMS Integrated INS has a built-in full temperature of 0.5°/h high-precision MEMS gyroscope, a 100ug high-precision quartz accelerometer and a survey-level GNSS receiver of multi-mode and multi-frequency for dynamic fast alignment or GNSS dual antenna support fast and high precision orientation up to 0.1°. The product supports GNSS/odometer/DVL/barometric altimeter and other sensors external, with excellent scalability. Through the use of multi-sensor data fusion technology, to combine inertial measurement and phase together, it can make the system have geographical adaptability and robustness greatly improved. The product can meet the application requirements of marine surveying and mapping and map surveying and mapping, matching the original data storage, the level of surveying and mapping, and the post-processing software for surveying and mapping navigation. Users can match according to their needs.
